AB  - A 16-week-long experiment was performed to compare the effect of sodium selenite (SS) and selenium-enriched yeast (SY) supplementation on eggshell quality and also to evaluate breaking force correlation with other parameters of shell quality originating from hens fed with selenium supplementation. One hundred Shaver 579 hens (27 weeks old) with similar body size were randomly divided for five dietary treatments: basal diet without selenium supplementation and basal diets with two levels of selenium supplementation (0.4 or 0.8 mg/kg) via SS or SY. No adverse effect of Se inclusion in hen's feed, regardless of its source, on shell breaking force, shell deformation, shape index, shell thickness and shell percentage, were observed throughout the current study (P > 0.05). Moderate correlations were found between breaking force and nondestructive shell deformation for all diets (P  lt  0.05). There was no significant overall correlation between egg breaking force and shell thickness or/and percentage shell in the presence of selenium supplemention (P > 0.05). Shape index in all four selenium-supplemented groups was not related to the breaking force (P > 0.05). Selenium supplementation of up to 0.8 mg/kg, regardless of its source, in the diet of laying hens in their first phase of laying does not adversely affect eggshell quality.

AB  - A 16-week experiment was conducted to compare effects of various levels of sodium selenite (SS) and Se-enriched yeast (SY), on the whole-egg Se content and hen's productivity. One hundred Shaver 579 hens, 27 weeks old, were placed on one of five experimental treatments. Each treatment was replicated four times with five hens per cage. Treatments consisted of feeding a low Se diet without supplementation (basal diet) or basal diet with one of two levels of supplemented Se (0.4 or 0.8 mg/kg) supplied by SS or SY. All supplemented treatments had significantly higher whole-egg Se concentration from basal diet (P  lt  0.05). On the same supplemented level, hens fed on SY had higher egg Se content from hens feed on SS (P  lt  0.001). No effects of dietary treatments on egg weight, percentages of dirty and cracked egg, and feed intake and conversion of feed were observed throughout the trial (P  lt  0.05). In the first 8 weeks, there was no significant difference (P  lt  0.05) in hen-day egg production among treatments. From the ninth week on to the end of the trial, supplementation of SY to hen's diet resulted in a higher egg production than SS (P  lt  0.01).

AB  - The effect of different levels of organic selenium (selenized yeast) on slaughter meat traits of fattening chickens (broilers) was investigated. Trial was carried out on 120 Hybro-PN chickens divided into four groups, in duration of six weeks. All groups of chickens were fed complete mixtures, and selenium was added to the food in the form of selenized yeast in the amount of 0 (I ); 0,3 (II); 0,6 (III) or 0,9mg/kg (IV-group). The highest average values of carcass yield 'conventional processing', 'ready to roast' and 'ready to grill' were recorded in chickens of group III (2059,6, 1851,97 and 1756,45g), with addition of 0,6mg Se/kg, followed by chickens of group II (2048,17, 1841,36 and 1748,57g) and group IV (1957,46, 1764,22 and 1676,05g) with 0,3 and 0,9mg/kg of added selenium, respectively, whereas the lowest values (1835,21, 1660,87 and 1572,61g) were established in chickens of group I without addition of this micro element. Average values of slaughter yields 'conventional processing', 'ready to roast' and 'ready to grill' were approximately the same in chickens of all investigated groups, and established differences showed no statistical significance (P > 0,05). The lowest breast mass was in I group (573,55g), and the highest in group III (657g). Chickens of groups II and IV (with 0,3 and 0,9mg Se/kg of feed) realized breast mass of 627,90 and 633,12g. Compared to group I, average breast mass of chickens in groups III and IV was considerably higher (P  lt  0,05 and P  lt  0,01). Share of breast in the mass of processed carcass was the highest in groups III and IV (37,40 and 37,86%), and the lowest in group II (36,0%). In chickens of group I the stated value was 36,47%. Average share of thighs in the mass of processed carcass was approximately the same in all investigated groups. The highest value (14,4%) was established in chickens of group II, and the lowest (13,98%), in chickens of III investigation group. Chickens fed organic selenium in diet (0,3, 0,6 and 0,9mg/kg) had by 3,80, 3,74 and 3,18% higher share of drumsticks in the mass of processed carcass compared to group I.

AB  - The aim of this study was to investigate the influence of organic and inorganic Fe supplementation on red blood picture, immune response and quantity of iron in organs of broiler chickens. The trial was conducted on 200 'Arbor Acres' chickens randomly alloted in four equal groups. Birds from all groups were fed standard broiler feed, supplemented with 40 mg/kg of Fe originating from different sources: Group I (FeSO4), Group II (Fe bounded to yeast), Group III (ferrous ascorbate) and Group IV (iron chelate). From each group, 10 birds were sacrificed on 21st, 35th and 42nd day and the following parameters were measured: erythrocyte count, hematocrite value, hemoglobin concentration, concentration of nonheme iron in spleen, liver and bone marrow (femur), degree of cutaneous hypersensitivity to PHA and titers of antibodies to Gumboro virus following vaccination. Addition of organic iron supplements resulted in increased erythrocyte count, hemoglobin concentration and hematocrite value on the 21st day. Different iron forms did not change the concentration of nonheme iron in the liver on the 21st and 42nd day. On the 35th day, the group supplemented with ferrous ascorbate had lower liver iron concentration. Also, concentrations of nonheme iron in the spleen were lower in groups supplemented with organic iron forms. The concentration of iron in the bone marrow decreased with age and the lowest values were recorded in the ferrous ascorbate supplemented group. The degree of cutaneous hypersensitivity to PHA was higher in groups supplemented with organic iron forms on the 21st and 35th day. Titers of anti-Gumboro antibodies were higher in the group supplemented with iron helate on the 35th day, but later (day 42) no significant differences were observed among groups.
AB  - Cilj ovog rada je bio da se ispita uticaj organski i neorganski vezanog gvožđa na crvenu krvnu sliku, imunski odgovor i količinu gvožđa u pojedinim organima. Ogled je izveden na ukupno 200 brojlera podeljenih u četiri jednake grupe. U smeše za ishranu brojlera dodavano je gvožđe u količini od 40 mg/kg koje je poticalo iz različitih izvora: fero sulfat (ogledna grupa I), gvožđe vezano za kvasac (ogledna grupa II), fero askorbat (ogledna grupa III) i helatno gvožđe (ogledna grupa IV). Kod piladi u dobi od 21, 35 i 42 dana praćeni su sledeći parametri: broj eritrocita, koncentracija hemoglobina, količina nehemskog gvožđa u jetri, slezini i kostnoj srži, vrednosti testa kožne preosetljivosti na fitohemaglutinin (PHA) i titar specifičnih antitela u krvnoj plazmi posle vakcinacije protiv Gumboro bolesti. Kod piladi u dobi od 21 dan svi ispitivani preparati gvožđa u kojima je ono bilo organski vezano, doveli su do povećanja broja eritrocita i koncentracije hemoglobina. Različiti oblici gvožđa u ishrani živine nisu uticali na količinu depononovanog nehemskog gvožđa u jetri piladi u dobi od 21 i 42 dan. Pilad u dobi od 35 dana, koja su u hrani dobijala fero askorbat, imala su značajno manje gvožđa deponovanog u jetri. Količina nehemskog gvožđa u slezini bila je manja kod piladi koja su hranom dobijala organski vezano gvožđe. Količina nehemskog gvožđa u kostnoj srži butne kosti piladi smanjivala se sa starošću jedinki a najmanja količina nehemskog gvožđa u kostnoj srži je zabeležena u grupi koja je hranom dobijala fero askorbat. Stepen kožne reaktivnosti na PHA bio je veći kod jedinki u dobi od 21 i 35 dana suplementiranih organski vezanim gvožđem. Upotreba helatno vezanog gvožđa u ishrani brojlera dovela je do statistički značajno veće produkcije antitela protiv Gumboro virusa nakon vakcinacije, kod piladi u dobi od 35 dana. Titar antitela kod jedinki u dobi od 42 dana u svim oglednim grupama bio je ujednačen.

Also, concentrations of nonheme iron in the spleen were lower in groups supplemented with organic iron forms. The concentration of iron in the bone marrow decreased with age and the lowest values were recorded in the ferrous ascorbate supplemented group. The degree of cutaneous hypersensitivity to PHA was higher in groups supplemented with organic iron forms on the 21st and 35th day. Titers of anti-Gumboro antibodies were higher in the group supplemented with iron helate on the 35th day, but later (day 42) no significant differences were observed among groups., Cilj ovog rada je bio da se ispita uticaj organski i neorganski vezanog gvožđa na crvenu krvnu sliku, imunski odgovor i količinu gvožđa u pojedinim organima. Ogled je izveden na ukupno 200 brojlera podeljenih u četiri jednake grupe. U smeše za ishranu brojlera dodavano je gvožđe u količini od 40 mg/kg koje je poticalo iz različitih izvora: fero sulfat (ogledna grupa I), gvožđe vezano za kvasac (ogledna grupa II), fero askorbat (ogledna grupa III) i helatno gvožđe (ogledna grupa IV). Kod piladi u dobi od 21, 35 i 42 dana praćeni su sledeći parametri: broj eritrocita, koncentracija hemoglobina, količina nehemskog gvožđa u jetri, slezini i kostnoj srži, vrednosti testa kožne preosetljivosti na fitohemaglutinin (PHA) i titar specifičnih antitela u krvnoj plazmi posle vakcinacije protiv Gumboro bolesti. Kod piladi u dobi od 21 dan svi ispitivani preparati gvožđa u kojima je ono bilo organski vezano, doveli su do povećanja broja eritrocita i koncentracije hemoglobina. Različiti oblici gvožđa u ishrani živine nisu uticali na količinu depononovanog nehemskog gvožđa u jetri piladi u dobi od 21 i 42 dan. Pilad u dobi od 35 dana, koja su u hrani dobijala fero askorbat, imala su značajno manje gvožđa deponovanog u jetri. Količina nehemskog gvožđa u slezini bila je manja kod piladi koja su hranom dobijala organski vezano gvožđe. Količina nehemskog gvožđa u kostnoj srži butne kosti piladi smanjivala se sa starošću jedinki a najmanja količina nehemskog gvožđa u kostnoj srži je zabeležena u grupi koja je hranom dobijala fero askorbat. Stepen kožne reaktivnosti na PHA bio je veći kod jedinki u dobi od 21 i 35 dana suplementiranih organski vezanim gvožđem. Upotreba helatno vezanog gvožđa u ishrani brojlera dovela je do statistički značajno veće produkcije antitela protiv Gumboro virusa nakon vakcinacije, kod piladi u dobi od 35 dana. Titar antitela kod jedinki u dobi od 42 dana u svim oglednim grupama bio je ujednačen.",

AB  - The aim of this study was to investigate the influence of organic and inorganic Fe supplementation on productivity of broiler chickens. The trial was conducted on 200 Arbor Acres chickens divided into four equal groups. Birds from all groups were fed standard broiler feed, supplemented with 40 mg/kg of Fe originating from different sources: Group I (FeSO4), Group II (Fe bound to yeast), Group III (ferrous ascorbate) and Group IV (iron chelate). From each group, 10 birds were sacrificed on the 21st, 35th and 42nd day and the following parameters were measured: body mass, daily body mass gain, food consumption and conversion rate. At the end of the trial, the highest average body mass was measured in the group supplemented with ferrous ascorbate (15,51% higher when compared with the group supplemented with FeSO4). The conversion rate was lower in birds supplemented with organic iron forms and had the lowest value in the group supplemented with ferrous ascorbate.

AB  - The objective of these investigations was to examine the influence of prebiotics based on mannan-oligosaccharides and polysaccharide complexes of micro elements (Fe, Cu, Zn, Mn) on production results and abattoir parameters for broilers of the hybrid Arbor Acres. The experiment was performed on 186 chicken divided into three equal groups, it lasted 42 days and was divided into 3 phases. The first phase lasted 21 days, the second 14, and the third seven days. The complete mix for initial fattening of broilers was used from days 1-21, and complete fodder mixes for closing fattening from days 21-35, and on days 35-42 of the experiment. Feeding was ad libitum and the broilers were maintained in a floor system. Broilers fed mixes of standard raw material composition and the usual nutritive values achieved an average daily growth of 49.10 g at an average daily feed consumption of 115.55 g and with food conversion of 2.35, while the yield was 71.90%. The addition of prebiotics based on mannan-oligosaccharides resulted in an increased average daily growth by 14.95% with a lower feed consumption by 2.67% and better conversion by 15.32%, while the yield was approximately the same as in the control group. The use of mixes to which polysaccharide complexes of micro elements have been added (Fe, Cu, Zn, Mn) resulted in a higher daily growth by 11.43%, with a lower feed consumption by 4.28% and better conversion by 14%. The yield was approximately the same in this group as in the controls. The results realized in these investigations, throughout the experimental period, indicate that the use of the examined additives significantly affected the growth and body mass of chicks and that it is nutritionally and economically justified.

Ogled je izveden na 186 pilića razvrstanih u tri jednake grupe, trajao je 42 dana i bio podeljen u 3 faze. Prva faza trajala je 21, druga 14, a treća 7 dana. Potpuna smeša za početni tov pilića korišćena je od 1-21 dana, a potpune krmne smeše za završni tov od 21-35 dana, odnosno 35-42 dana ogleda. Ishrana je bila po volji, a pilići su bili u uslovima podnog sistema držanja. Brojleri hranjeni smešama standardnog sirovinskog sastava i uobičajene hranljive vrednosti, ostvarili su prosečan dnevni prirast od 49,10 g pri prosečnoj dnevnoj konzumaciji hrane od 115,55 g i uz konverziju hrane od 2,35 dok je randman bio 71,90%. Dodavanje prebiotika na bazi manan-oligosaharida dovelo je do povećanja prosečnog dnevnog prirasta za 14,95% pri manjoj konzumaciji hrane za 2,67% i boljoj konverziji za 15,32%, dok je randman bio približno isti kao u kontrolnoj grupi. Korišćenjem smeša u koje su dodavani polisaharidni kompleksi mikroelemenata (Fe, Cu, Zn, Mn) postignuti su veći dnevni prirasti za 11,43%, pri manjoj konzumaciji hrane za 4,28% i boljoj konverziji za 14%. Randman je i u ovoj grupi bio približno isti kao u kontrolnoj. Rezultati ostvareni u ovim istraživanjima, u toku celog oglednog perioda, ukazuju da je upotreba ispitivanih aditiva značajno uticala na prirast i telesnu masu pilića i da ima nutritivno i ekonomsko opravdanje.

AB  - Thirty-nine gilts, 82 days old, divided into 3 groups, were fed the main diet supplemented by 0; 0.3 and 0.6 mg Se/kg in the form of Seenriched yeast during 99 days. Selenium levels of 0.3 and 0.6 mg/kg diet led to no significant bodyweight gain nor increase in body mass in any of the studied periods. However, gilts fed a diet supplemented with selenium (0.3 and 0.6 mg/kg) during the whole research period had somewhat higher body mass (1.17 and 3.36%, respectively) and higher average daily bodyweight gain (1.07 and 4.30%, respectively). Selenium supplemented diet influenced also more efficient feed conversion for 3.11 and 2.18%, respectively. The highest content of selenium was observed in the kidneys, then in liver and heart whilst the lowest selenium content was observed in the leg and neck musculature. Selenium concentration in kidneys ranged from 1.23 mg/kg to 1.38 mg/kg and no statistically significant differences were established among studied groups. Selenium concentration in the liver was 3-4 times lower, and in the heart muscle even up to 6 times lower in comparison with the kidneys. Among the studied groups statistically significant differences were established (P lt 0.01) for selenium levels in liver and heart muscle. The highest levels were observed in the group fed 0.6 mg Se/kg diet, that is, in the liver 0.511 mg/kg and in the heart 0.313 mg/kg. Selenium concentration in the leg and neck muscle was twice, i.e., three times higher in gilts fed 0.3 mg Se/kg and 0.6 mg Se/kg diet in relation to animals fed no supplemented selenium diets (P lt 0.01).
AB  - Trideset i devet nazimica starih 82. dana, podeljenih u 3 grupe, hranjeno je osnovnim obrokom dopunjenim sa 0, 0,3 i 0,6 mg Se/kg u obliku seleniziranog kvasca u toku 99 dana. Nivoi selena od 0,3 i 0,6 mg/kg hrane nisu doveli do značajnog povećanja prirasta i telesne mase ni u jednom ispitivanom periodu. Međutim, nazimice hranjene obrocima sa dodatkom selena (0,3 i 0,6 mg/kg) u toku celog perioda ispitivanja imale su nešto veću telesnu masu (1,17 i 3,36%, redom) i prosečan dnevni prirast (1,07 i 4,30%, redom). Dodati selen u hranu je uticao i na efikasnije iskorišćavanje hrane za 3,11 i 2,18% redom. Najveći sadržaj selena ustanovljen je u bubrezima, a zatim u jetri i srcu, a najmanji u butnoj i vratnoj muskulaturi. Koncentracija selena u bubrezima kretala se od 1,23 do 1,38 mg/kg i nisu ustanovljene statistički značajne razlike između ispitivanih grupa. U jetri, koncentracija selena je bila 3-4 puta niža, a u srčanoj muskulaturi čak i do 6 puta niža nego u bubrezima. Između ispitivanih grupa ustanovljene su statistički značajne razlike (P lt 0,01) u nivou selena u jetri i srčanoj muskulaturi. Najviši nivo ustanovljen je u grupi hranjene sa 0,6 mg Se/kg hrane i to u jetri 0,511, a u srcu 0,313 mg/kg. Koncentracija selena u butnoj i vratnoj muskulaturi bila je dva, odnosno tri puta veća kod nazimica hranjenih sa 0,3 i 0,6 mg Se/kg hrane u odnosu na grla koja nisu dobijala dodatak selena (P lt 0,01).

Međutim, nazimice hranjene obrocima sa dodatkom selena (0,3 i 0,6 mg/kg) u toku celog perioda ispitivanja imale su nešto veću telesnu masu (1,17 i 3,36%, redom) i prosečan dnevni prirast (1,07 i 4,30%, redom). Dodati selen u hranu je uticao i na efikasnije iskorišćavanje hrane za 3,11 i 2,18% redom. Najveći sadržaj selena ustanovljen je u bubrezima, a zatim u jetri i srcu, a najmanji u butnoj i vratnoj muskulaturi. Koncentracija selena u bubrezima kretala se od 1,23 do 1,38 mg/kg i nisu ustanovljene statistički značajne razlike između ispitivanih grupa. U jetri, koncentracija selena je bila 3-4 puta niža, a u srčanoj muskulaturi čak i do 6 puta niža nego u bubrezima. Između ispitivanih grupa ustanovljene su statistički značajne razlike (P lt 0,01) u nivou selena u jetri i srčanoj muskulaturi. Najviši nivo ustanovljen je u grupi hranjene sa 0,6 mg Se/kg hrane i to u jetri 0,511, a u srcu 0,313 mg/kg. Koncentracija selena u butnoj i vratnoj muskulaturi bila je dva, odnosno tri puta veća kod nazimica hranjenih sa 0,3 i 0,6 mg Se/kg hrane u odnosu na grla koja nisu dobijala dodatak selena (P lt 0,01).",

AB  - The main objective of this study was to investigate the importance of the sires effect on fenotypic variability of production traits of performance tested boars of Large White, Landrace. and Hampshire breeds of pig. The data used in this study were collected from 738 performance tested young boars at the PKB Pig Testing Station in Padinska Skela, from 1995 to 2001. Analysed traits were initial age (IA), final age (FA), test duration (TD), average daily gain on test (ADG), lifetime ADG (LADG), amount of total consumed feed (TF), feed conversion ratio (FCR), daily feed intake (DPI) and body composition traits taken by ultrasonic equipment PIGLOG 105 (backfat thickness - BF1 and BF2, muscle depth - MD and lean meat content - LM) Data was analysed by fixed models of least squares method. Analysis of variance showed that sires nested within Hampshire breed highly significant influenced all investigated traits. Growth, feed efficiency and body composition traits except muscle depth, were highly significant influenced by sires of Large White breed. All feed efficiency traits and muscle depth were not influenced by sires within Swedish Landrace breed.
AB  - Osnovni cilj ovih istraživanja je bio da se utvrde razlike između grupa kombinovanih podataka punih i polusrodnika nerastova-očeva tri različite rase svinja za proizvodne osobine evidentirane u direktnom testu u uslovima centralne testne stanice. Istraživanja su obavljena u Stanici za ispitivanje proizvodnih sposobnosti svinja, PK "Beograd" u Padinskoj Skeli. Ispitivanjem je bilo obuhvaćeno ukupno 738 grla tri rase svinja i to: švedskog landrasa (n = 129), velikog jorkšira (n = 473) i hempšira (n = 136). Testirani nerastovi su bili potomci od 61 oca, tako da je za sve tri rase prosečan broj potomaka testiranih po ocu iznosio 12,1. Broj očeva od kojih su vodila poreklo testirana grla rase švedski landras iznosio je 15, veliki jorkšir 34 i hempšir 12. Ocena i testiranje hipoteze o uticaju efekata nerastova-očeva na variranje proizvodnih osobina izvršena je upotrebom metoda najmanjih kvadrata (Harvey, 1990).

AB  - The effect of high levels of inorganic selenium (NaiSeOs) was investigated on activity GSH-Px in blood plasma of chickens. For experiment, 140 chickens were used which were divided in 7 groups. The experiment lasted 42 days. The chickens of I group were not fed supplemental selenium. The chickens of II III, IV, V, VI and VII group were fed 2, 5, 10, 15, 20 and 30mg Se/kg of diet in form of Na2SO3. For determination of activity of GSH-Px spectrografic method was used. The highest activity of GSH-Px was found at the beginning of the experiment in all examined chickens (the eleventh day). The chickens of II, III, IV and V group had significantly higher activity and chickens of VI and VII group had lower activity then I group.

AB  - The goal of this research was to investigate the effect of various levels of organic selenium (selenized yeast) on the weight gain and feed utilization of chicken in fattening. The experiment was carried out on 120 chicken of line hybrid Hybro-PN, divided into four groups (treatments), lasting six weeks. All groups of chicken were fed complete mixtures, while selenium was added to feed in the form of selenized yeast, in quantities of 0 (Group I); 0.3 (II) 0.6 (III), or 0.9mg/kg (IV). Chicken were measured, and care was taken to keep groups uniform (Groups: I - 36.17g; II - 37.01g; III - 37.16g, and IV 36.59g). During the experiment, every seven days, body weight of all animals was measured, as well as feed consumption for each experimental group. At the end of fattening, the highest body weight was established for chicken in Group III (2647.50g), followed by chicken in Groups II and IV (2595.89 and 2526.55g). Mentioned values were statistically significant (PO.01) by chicken and groups (2309.lg). Average daily feed consumption during the whole fattening period was highest in Group III, and lowest in Group I. For the last week of fattening it amounted to 196.38g (Group III), i.e. 179.41g (Group I). However, for chicken in Groups II and IV, these values were somewhat lower, as compared to chicken in Group III (190.50 and 185.15g). Food consumption per 1 kg gain was lowest in groups fed rations with added organic selenium (Group II - 1.65; III and IV - 1.67). Chicken in group I had the worst feed conversion (1.73).

AB  - An experiment lasting 45 days was performed on 125 Hybro broilers divided into five groups. All compounds for broiler feed mixes used in the experiment contained 0.15 mg Se/kg, in the form of sodium selenite. The control group (K-group) of broilers was fed mixes without added organic selenium, and the experimental groups with mixes to which selenium, in the form of selenized-yeast, was added in quantities of 2, 5, 10, or 15 mg/kg. Selenized yeast (ICN - Gaienika) was obtained from beer yeast and contained 1.51, or 1.45 mg/g total, or organically bound selenium. At the beginning of the fattening period, GSH-Px plasma activity in broilers of the K-group ranged around 16.55 μkat/L, while GSH-Px plasma activity in broilers of experimental groups was statistically significantly higher, but without any major differences among the individual groups (on the average 25.53fjkat/L). In the blood plasma of K-group, GSH-Px activity dropped already in the second week of life and was maintained at a relatively constant level (about 10 μkat/L) until the end of the experiment. The same phenomenon was observed in the experimental groups, but the trend of declining GSH-Px activity in blood plasma was more expressed, and, contrary to the control group, was expressed also in the later phases of the experiment. In the 3rd week of the fattening period, GSH-Px plasma activity in broilers of the control and experimental groups was relatively equal, and then the plasma activity of GSH-Px in broilers of the experimental groups decreased, but there were no major differences among the individual groups.
AB  - Ogled je izveden na, 125 hibro brojlera podeljenih u pet grupa. Ogled je trajao 42 dana. Sve smeše za ishranu brojlera u ogledu sadržavale su 0,15 mg Se/kg, u formi natrijum selenita. Brojleri kontrolne grupe hranjeni su smešama bez dodatog organskog selena, a brojleri oglednih grupa dobijale su smese u ko/eje selen, u obliku selenizovanog kvasca, dodat u količini od 2 5, 10 ili 15 mg/kg. Selenizovani kvasac (ICN - Galenika) dobijen je od pivskog kvasca i sadržao je 1,51, odnosno 1,45 mg/g ukupnog, odnosno organski vezanog selena. Na početku tova, aktivnost GSH-Px u plazmi brojlera K-grupe kretala se oko 16,55 μkat/L, dok je aktivnost GSH-Px u plazmi brojlera oglednih grupa bila statistički značajno viša, ali bez većih razlika između pojedinih grupa (prosečno 25,53 μkat/L). U krvnoj plazmi K-grupe aktivnost GSH-Px pada već u drugoj nedelji života i održava se relativno konstantnom (oko 10 μkat/L) do kraja ogleda. U oglednim grupama zapaža se isti fenomen ali je trend smanjivanja aktivnosti GSH-Px u krvnoj plazmi izrazitiji, pri Čemu je, za razliku od kontrolne grupe, izražen i u kasnijim fazama ogleda. U trećoj nedelji tova aktivnost GSH-Px u krvnoj plazmi brojlera kontrolne i oglednih grupa je relativno jednaka, a zatim je aktivnost GSH-Px u plazmi brojlera oglednih grupa bila niža bez većih razlika između pojedinih grupa.

AB  - All mineral matter, essential or non-essential, can have a significant influence on production results and the health of animals, if large quantities of them are present in a feed ration. A maximally tolerant content depends on the animal specie and category. Many factors, such as physiological status (growth, lactation, etc.), nutritive status, content and ratio of nutritive matter in the ration, duration of exposure, and the biological level of utilization of elements, also affect the maximally tolerant content of mineral matter in feed. The content of certain mineral matter in plant feed significantly depends on the soil factor, as well as the content and level of utilization of mineral matter from the soil. Mn, Se and Mo can be present in plant feed in such quantities as to induce toxicosis. Industrial contaminants, Cd, Pb or F, can contaminate plants, in particular their leaves, in quantities which lead to the appearance of clinical signs of conventional toxicosis. Moreover, natural water can contain large quantities of S, F, Na, Mg, or Fe, and certain mineral matter can get into water through industrial waste. In addition to the above, it is possible to cause unwanted effects through the frequent, but primarily unprofessional use of mineral additives, since it is extremely important, besides meeting the mineral requirements of each individual element, to secure a ratio among the mineral matter themselves as well as with other nutritive matter. Mineral matter present in food are in mutual interference, and these relations can be synergistic or antagonistic. The sufficiency of a large number of mineral matter has a negative effect on the utilization of other matter (conditional and/or border deficiency), while certain elements cause the clinical appearance of toxic effects. The accidental intake of large quantities of certain mineral matter is revealed as clinical signs of acute toxicosis, which is very different from chronic effects caused by the intake of increased quantities of mineral matter over a longer time period.

AB  - The objective of these investigations was to examine the influence of raw and thermally processed soybean kernels (ZP Lana and ZP Nena) on growth and feed utilization of broiler chicks. The experiment was conducted on 200 chickens (Arbor Acres) divided into four groups (treatments). The first group was fed a mix containing raw soybean kernels (ZP Lana) with a smaller quantity of trypsin inhibitors, and the third with raw kernels of a standard varietry (ZP Nena). The second and fourth groups were administered mixes containing raw kernels that were previously thermally processed. In the first period of the fattening process (days 1 -21), the amount of raw or thermally processed kernel was 20%, in the second period (days 22-35) 24%, and in the third period (days 36-42) 22 %. The experiment lasted 42 days. The chickens were maintained on the floor, feed was ad libitum, comprising complete mixes composed on the grounds of the recommendations for the given hybrid. The results obtained in the course of these investigations over the entire experimental period indicate that the use of thermally processed soybean kernels (groups two and four), in comparison with the use of raw kernels (groups one and three), significantly (P lt 0.01) affected growth and body mass of chickens. Furthermore, significantly bigger values (P lt 0.01) for the given parameters were determined also in chickens of group one in comparison with group three. Using thermally processed kernels (groups two and four) affected an increase in the daily consumption of feed not only in a certain period, but during the duration of the entire experiment(days 1-42). The listed treatments (groups two and four) in this period (days 1-42) also considerably increased feed conversion (1.83 and 1.85) in comparison with experimental groups one and three.
AB  - Cilj ovih istraživanja je bio da se ispita uticaj sirovog i termički obrađenog zma soje (ZP Lana i ZP Nena) na prirast i iskorišćavanje hrane pilića u tovu. Ogled je izveden na 200 pilića (Arbor Acres) podeljenih u četiri grupe (tretmana).

abstract = "The objective of these investigations was to examine the influence of raw and thermally processed soybean kernels (ZP Lana and ZP Nena) on growth and feed utilization of broiler chicks. The experiment was conducted on 200 chickens (Arbor Acres) divided into four groups (treatments). The first group was fed a mix containing raw soybean kernels (ZP Lana) with a smaller quantity of trypsin inhibitors, and the third with raw kernels of a standard varietry (ZP Nena). The second and fourth groups were administered mixes containing raw kernels that were previously thermally processed. In the first period of the fattening process (days 1 -21), the amount of raw or thermally processed kernel was 20%, in the second period (days 22-35) 24%, and in the third period (days 36-42) 22 %. The experiment lasted 42 days. The chickens were maintained on the floor, feed was ad libitum, comprising complete mixes composed on the grounds of the recommendations for the given hybrid. The results obtained in the course of these investigations over the entire experimental period indicate that the use of thermally processed soybean kernels (groups two and four), in comparison with the use of raw kernels (groups one and three), significantly (P lt 0.01) affected growth and body mass of chickens. Furthermore, significantly bigger values (P lt 0.01) for the given parameters were determined also in chickens of group one in comparison with group three. Using thermally processed kernels (groups two and four) affected an increase in the daily consumption of feed not only in a certain period, but during the duration of the entire experiment(days 1-42). The listed treatments (groups two and four) in this period (days 1-42) also considerably increased feed conversion (1.83 and 1.85) in comparison with experimental groups one and three., Cilj ovih istraživanja je bio da se ispita uticaj sirovog i termički obrađenog zma soje (ZP Lana i ZP Nena) na prirast i iskorišćavanje hrane pilića u tovu. Ogled je izveden na 200 pilića (Arbor Acres) podeljenih u četiri grupe (tretmana).

AB  - Considering that our previous research has indicated some positive effects of probiotics used in nutrition of sows and suckling piglets, as well as piglets in rearing, investigation designed in this case had the objective to investigate the effect of introduction of probiotic Paciflora-C-10, based on Bacillus spp C.I.P. 5832 in nutrition of fattening pigs. Investigations were carried out on Experimental pig farm of the Institute for Animal Husbandry, Belgrade-Zemun. Crietria for evaluation of obtained results were production performance, degree of use of nutritious substances slaughter parameters and economical analysis determined as price of gain of 1 kg of body mass. It was established that introduction of probiotics has induced the increase of body mass gain by 3,88%, feed conversion by 2,81% degree of utilization of dry and organic matter as well as crude proteina in mixtures. Also, in regard to slaughter traits, it was established that use of probiotic had positive effect on dressing percentage. No effect on food consumption, meatiness in warm carcasses or price of body mass gain was determined on experimental animals.

AB  - The experiment was carried out with 260 chickens divided into 13 groups, for 6 weeks. All chicken groups were fed with commercial mixtures, and selenium was added in their feed in the form of sodium selenite or selenized yeast at following concentrations: 0, 2, 5, 10, 15, 20 or 30 mg Se/kg. Three birds from each group were sacrificed on the 10th, 24th and 42nd days of the experiment. All internal organs were inspected and parts of the liver and kidneys were subsequently taken for pathohistological investigations. In birds fed with 2 and 5 mg Se/kg feed in the form of sodium selenite neither pathomorphological nor pathohistological alterations in the liver or kidneys were noticed at any of the monitoring intervals. In birds fed with the higher rates of inorganic selenium (10, 15, 20 or 30 mg Se/kg feed) certain pathohistological alterations occured that were more marked with the higher concentrations of selenium in the feed or after longer duration of intake. No alterations were noticed in the mentioned organs from chickens supplied with 2, 5, 10 or 15 mg Se/kg feed in the form of selenized yeast. Alterations of liver and kidneys were encountered only in birds treated with exceptionally high levels of organic selenium (20 or 30 mg Se/kg feed). In chickens fed with 10, 15, 20 or 30 mg Se/kg feed in the form of Na2SeO3, the liver was enlarged and of a lighter coloration, while pathohistological evidence varied between intracellular edema and necrotic changes. In kidneys, edema of the renal tubules was noticed and at the highest levels vacuolization and ballooning dystrophy of cells with loss of nuclei was found. In chickens supplied with 20 or 30 mg Se/kg feed in the form of selenized yeast pathohistological changes were less marked than in those fed with the same amounts of Se in the form of Na2SeO3.

Po tri životinje iz svake grupe su žrtvovane 10., 24. i 42. dana ogleda. Izvršen je pregled svih unutrašnjih organa, a potom su uzimani delovi jetre i bubrega za patohistološka istraživanja. Kod pilića hranjenih sa 2 i 5 mg Se/kg hrane u obliku natrijum selenita nisu uočene patomorfološke ni patohistološke promene na jetri i bubrezima ni u jednom od ispitivanih vremenskih intervala. Kod pilića hranjenih sa višim nivoima neorganskog selena (10, 15, 20 ili 30 mg Se/kg hrane) uočene su određene patohistološke promene koje su bile izraženije sa povećanjem koncentracije selena i dužinom konzumiranja. U pilića koji su dobijali 2, 5, 10 ili 15 mg Se/kg hrane u obliku seleniziranog kvasca nisu ustanovljene promene na pomenutim organima. Promene na jetri i bubrezima su se javljale samo kod životinja tretiranih izuzetno visokim nivoima organskog selena (20 ili 30 mg Se/kg hrane). U pilića hranjenih sa 10, 15, 20 ili 30 mg Se/kg hrane u obliku natrijumselenita, jetra je bila uvećana i svetlije boje a patohistološki nalaz se kretao od intracelularnog edema do nekrotičnih promena. Na bubrezima je uočen edem bubrežnih kanalića, a pri najvišim dozama ustanovljena je vakuolizacija i balonirajuća distrofija ćelija sa gubitkom jedara. U pilića koji su dobijali 20 ili 30 mg Se/kg hrane u obliku seleniziranog kvasca, patohistološke promene su bile manje izražene nego kod onih hranjenih sa istim nivoima Se u obliku natrijum-selenita.

AB  - Animals need microelements in small quantities which participate in almost all physiological and biochemical processes. Microelement resorption does not depend only on their content in feed, but also on the age of the animal, the electrochemical reaction in the intestines and the form of the microelement itself. The choice of the source is based on the microelement content in solid state, its solubility in the organism, availability and utilization. Oxides, chlorides and carbonates are poorly soluble, and chlorides are hygroscopic, and carbonates oxidize rapidly. Sulphates are durable salts easy to purify, and sulphate ions are easily excreted from the organism. In addition to nonorganic forms of mineral matter, so-called chelated forms are today increasinlgy being used, in fact, organically bound microelements. Minerals bound to an amino acid or peptide are better protected during their passage through the stomach, and the resorption of a chelated form of copper is considerably higher than resorption from sulphates. The resorption of organically bound microelements does not proceed in the conventional manner (carrier/diffusion), so that there is no direct homeostatic control at the level of enterocytes, and retention and the biological half-life of a chelated form are bigger than those of an anorganic form.
AB  - Životinjama su mikroelementi potrebni u malim količinama i učestvuju u skoro svim fiziološkim i biohemijskim procesima. Resorpcija mikroelemenata ne zavisi samo od sadržaja u hrani, nego i od doba životinje, elektrohemijske reakcije u crevima i oblika u kome se mikroelement nalazi. Izbor izvora zasniva se na sadržaju mikroelementa u čistom stanju, rastvorljivosti u organizmu, dostupnosti i iskoristivosti. Oksidi, hloridi i karbonati slabo rastvorljivi, a pored toga hloridi su higroskopni, a karbonati brzo oksidišu. Sulfati su postojane soli, lake za prečišćavanje, a sulfatni jon se lako izlučuje iz organizma. Pored neorganskih formi mineralnih materija, danas se sve više koriste, takozvani "helatni" oblici, odnosno organski vezani mikroelementi. Minerali vezani sa amino-kiselinom ili peptidom bolje su zaštićeni za vreme pasaže kroz želudac, a resorpcija helatne forme bakra je znatno veća od resorpcije iz sulfata. Resorpcija organski vezanih mikroelemenata se ne odvija konvencionalno (nosač/dufuzija), pa direktna homeostatska kontrola na nivou enterocita ne postoji, a retencija i biološ ki poluživot helatnog oblika su veći kod anorganske forme.

Pored neorganskih formi mineralnih materija, danas se sve više koriste, takozvani "helatni" oblici, odnosno organski vezani mikroelementi. Minerali vezani sa amino-kiselinom ili peptidom bolje su zaštićeni za vreme pasaže kroz želudac, a resorpcija helatne forme bakra je znatno veća od resorpcije iz sulfata. Resorpcija organski vezanih mikroelemenata se ne odvija konvencionalno (nosač/dufuzija), pa direktna homeostatska kontrola na nivou enterocita ne postoji, a retencija i biološ ki poluživot helatnog oblika su veći kod anorganske forme.",

AB  - The paper examined the effect of protein levels in the diet of lactating sows and parity on protein content in internal vital organs of sows following the end of lactation. Due to an insufficient intake of proteins from feed lactating sows engage proteins from vital internal organs in order to meet the requirements for milk production. The paper established significant differences depending on protein level in lactating sow diet on protein level and mass in the liver. The protein level and mass in the liver were higher in sows with rations with a higher protein level. The protein mass in kidneys depended on the protein level in the ration, and it increased slightly with its increase. It was established that parity has an effect on the protein level in the liver of sows.

Usled nedovoljnog unošenja proteina iz hrane, krmače dojare da bi zadovoljile potrebe za produkcijom mleka angažuju proteine iz vitalnih unutrašnjih organa. U radu su utrvrđene značajne razlike u zavisnosti od nivoa proteina u obroku krmača u laktaciji na nivo i masu proteina u jetri. Nivo i masa proteina u jetri su viši kod krmača koje dobijaju obroke sa višim nivoom proteina. Masa proteina bubrega zavisi od nivoa proteina u obroku, sa njegovim povećanjem i ona se blago povećavala. Ustanovljeno je da paritet utiče na nivo proteina u jetri krmača.

AB  - The effect of microclimate parameters on the production of pigs was analysed in this paper. It was proved that the strongest influence on the levels of the low critical and high critical temperature (LCT and HCT) have the body weight of pigs, condition, feed intake, air speed, thermal isolation of piggeries, type of floor, thermal waste, system of pig housing e.t.c. In sucking piglets and right after weaning, ambient temperature lower then LCT is the most frequent problem that leads to reduced weight gain, feed intake increase and possible indigestions and diarrhoea. In growing pigs temperature below LCT leads to the increase of feed intake, poorer feed conversion, while the influence on the daily weight gain was less expresed. In pregnant sows LCT ranged from 12-23 oC depending on the condition of the sow, the amount of feed, system of pig housing and the quality of housing. High temperature is a problem in lactating sovvs since it lessened the feed intake and amount of milk. It also increased wastages of nutrients from the organism which is of detriment to the future reproductive efficiency.

Kod prasadi na sisi i posle zalučenja temperatura ambijenta niža od DKT najčešće je problem koji uzrokuje smanjenje dnevnog prirasta, povećanje utroška hrane i pojavljivanje indigestija i proliva. Kod svinja u porastu i tovu temperatura niža od DKT uzrokuje povećanje potrošnje i pogoršanje konverzije hrane, dok je uticaj na dnevni prirast manji. Kod suprasnih krmača DKT varira u vrlo širokom intervalu od 12 do 23 oC u zavisnosti od kondicije krmače, količine hrane, sistema držanja i kvaliteta smeštaja. Visoka temperatura je problem kod krmača u laktaciji pošto uzrokuje smanjenje potrošnje hrane, količine mleka i povećanja gubitaka hranljivih materija iz organizma, što negativno deluje na kasniju reproduktivnu efikasnost.

AB  - Investigations covered reproductive characteristics of sows during two different periods. During the first period, sows were fed silages wet corn kernels, soybean and sunflower meal, with a high level of mycotoxins (Table 2). During the second period, animals were fed with a ration which included fodder which was not contaminated with higher than permitted levels of mycotoxins (artificially dried corn kernels, soybean and sunflower meal). During both periods, investigations began after weaning of piglets and continued during two consecutive titters. The sexual urge first appeared after loss of milk in sows fed compounds which included fodder with a lower level of mycotoxins (15.87 days), and it first appeared in sows fed compounds with fodder containing a high degree of contamination after 21.01 days (the second period). The success of insemination was better in the second (84,12%) than in the first period (71.44%). Sows were not impregnated in 1,120 case during the second period and 1,765 during the first period. The percent of successfully inseminated sows was bigger in the second (80,69%) than in the first period (68.56%). The negative effects of mycotoxins resent in feed can be eased with the early or timely determination of their presence in fodder and the consequent elimination of contaminate feed from use and/or its possible dilution or mixing with mycotoxin-free fodder.

AB  - With the aim to investigate the effect of adding enzyme to the diet of weaned piglets on their productive traits, the trial was performed on the 56 Swedish Landrace piglets, classified into 4 groups. The concentration of added enzyimes was 0.1%. The body weight gain of piglets fed with amylolitic enzyime addition in diets was increased by 5.23% and feed conversion was lower by 3.83% in comparison to the control. A positive effect of the enzymes added was also registered in the 4th group (proteolytic enzyme) where the daily weight gain was lower by 6.98% and the feed conversion was lower by 5.26%. The highest stimulatory effect was observed in the first two weeks when the daily weight gain in piglets of 2nd, 3rd and 4th group was higher by 31.15, 20.49 and 35.25%, respectively, compared to the control group.
AB  - U cilju ispitivanja efekata dodavanja pojedinačnih enzima obrocima odlučene prasadi na njihove proizvodne sposobnosti, izveden je ogled sa ukupno 56 prasadi rase švedski landras, podeljenih u četiri grupe. Koncentracija dodatih enzima iznosila je 0,1%. Dodatak amilolitičkog enzima hrani odlučene prasadi doveo je do porasta dnevnog prirasta za 5,23% i do smanjenja utroška hrane za 3,83% u poređenju sa kontrolnom grupom. Grupa prasadi koja je hranjena smešom sa dodatkom celulitičkog enzima imala je za 6,40% bolji dnevni prirast i za 3,83% bolju konverziju u odnosu na kontrolnu grupu. Prasad IV grupe, sa dodatkom proteolitičkog enzima u hrani, ostvarila su dnevni prirast za 6,98% veći nego I, kontrolna grupa i za 5,26% efikasnije iskorišćavanje hrane. Posebno veliki uticaj dodati enzimi ostvarili su u prvih 14 dana ogleda kada su prasad II, III i IV grupe imala za 31,15, 20,49 i 35,25% veći dnevni prirast u poređenju sa kontrolnom grupom.

AB  - To attain better feed utilization, longer preservation, easier manipultion and higher production and better quality of food of animal orgin as the final goal, besides raw materials, feed mixes contain numerous pronutrients (additives), added to perform different effects, in a narrower sense, the term pronutrient implies heterogenous substances, which have no diverse effects and have to be efficient in the manner of use. Basically, all pronutrients have to reach the goal of keeping optimal animal health status and to increase production of food of animal origin without adverse and negative effects. The development of biotechnology had a great part in the appearance of natural alternatives which are able to fulfil and satisfy the high demands of highly productive animals, as well as those of the consumer lobby and environmental protection movements. Growth promoters based upon physiological mechanisms and production potential of the animal have an unquestionable adventage, not only because of the lack of residues in food of animal origin; but also because of their ecological safety and decrease of envirnomental pollution by undigested materials. Demand continues to grow for "all natural", non-pharmaceutical feed additives with growth enhancing effects in food animals. Special attention is paid to minerals (anorganic and organic sources), growth stimulators (antibiotics, probiotics prebiotics), substances for better feed utilization (enzymes, acidifers) adsorbents.
