AB  - The aim of this study was to investigate changes of serum testosterone, scrotal circumference, body weight, and semen characteristics in a Meat Institute Sheep (MIS) population during their developing period (between 3 and 17 months). Correlative relationships among parameters were also tested. Body weight and scrotal circumference were measured monthly, blood samples for testosterone levels were taken bimonthly (3-17 months), and semen samples were collected by an electroejaculator between the ages of 9 and 17 months. The analysis showed that the average serum testosterone levels ranged from 1.83 to 13.28 ng/mL and significantly depended on the age of the lambs (P  lt  0.05). The trend in the level of serum testosterone was characterized by pronounced variability throughout the study period. Changes in scrotal circumference and body weight were significantly dependent on age. Ejaculate volume, sperm motility, and the percentage of live spermatozoa increased with age, except for the percentage of abnormal spermatozoa, which decreased with age. Correlations among serum testosterone, scrotal circumference, and body weight were moderately to highly positive and highly significant. All parameters of semen quality were poorly correlated with testosterone and body weight, while scrotal circumference was in moderate correlation only with ejaculate volume and live sperm count (P  lt  0.05).

AB  - The aim of this research was to determine if there are differences in sexual reaction of the grown sheep II de frans breed depending on the body weight of treated eves during induction and synchronization of estrus with fluorogestonacetate (FGA) + PMSG in anoestrus season. Total number of 262 eves was treated and they were divided in to three groups. The first group consisted of the sheep whose body weight was from 40 to 50kg, the second group of the sheep whose weight was from 50-60kg and the third group of the sheep whose weight was above 60kg. Each group received sponges of FGA. After removal of the sponges all sheep received intramuscular injection of 500 i.u of PMSG. The 'Sugonal' prepared by Veterinary institute Subotica was used. After two days the insemination was conducted. The results show that from first group 43.78% sheep lambed, from second group 46.66% and from third group 59.32%. Average sheep fertility after treatments was for the first group 113.28%, 118.37% for the second group and 137.14% for the third group. The ratio of singles, twins and triplets was for the first group 72:28:0 %, for the second group 70.69:24.14:5.17%, and for the third group 47.92:45.83:6.25%. Determined differences between number of lambed sheep and treated sheep, fertility and number of twins, as well as between investigated groups were statistically significant (P lt 0,05). Conclusion is that sheep of body weight above 60kg have had significantly better reaction to the treatment.
AB  - Cilj ovog istraživanja je da se utvrdi da li postoje razlike u polnom reagovanju odraslih ovaca rase II d,frans u zavisnosti od telesne mase tretiranih plotkinja pri indukciji i sinhronizaciji estrusa pomoću fluorogeston acetata (FGA) i gonadotropnog hormona gravidnih kobila (SGŽK ili PMSG) u sezoni anestrije. Ukupno je tretirano 262 plotkinje, podeljene u tri grupe. UI grupu svrstane su ovce telesne mase 40-50 kg t.m., u II grupu 50-60 kg t.m. i u III grupu > od 60 kg t.m. (kontrolna grupa). Životinjama svih grupa intravaginalno su aplikovani sunđeri (30 mg fluorogeston acetata/sunđer) koji su ostali u vagini 12 dana. Na dan vađenja sunđera, ovcama je s.k., jednokratno aplikovan SGŽK u dozi od 500 i.j./grlo. Nakon dva dana izvršen je 'pripust iz ruke'. Dobijeni rezultati pokazuju da se iz I grupe ojagnjilo 43,78%; iz II 46,66% a iz III 59,32% tretiranih plotkinja. Prosečna plodnost ovaca po tretmanima I, II i III je iznosila 116,28% kod I grupe, 118,37% Il grupe, sto je ispod očekivanih vrednosti za rasu, dok je plodnost od 137,14% kod III grupe u granicama prosečnih vrednosti za rasu. Utvrđene razlike između ispitivanih grupa, u korist III grupe u odnosu na I i II grupu, bile su statistički značajne (P lt 0,05). Zaključak je da su ovce III grupe prosečne telesne mase od 67,68 kg, znatno bolje reagovale na primenjeni tretman jer je postignuta očekivana plodnost.

AB  - The social rank refers to the relative position of an individual animal within the dominant hierarchy developed in a group. In rams, social rank is mostly associated with body mass, body size and body condition. However, although the body mass is generally considered as one of the main determinants of social rank, only few studies have been carried out for the purpose of associating of the social behavior and body development of these animals. Objective of this research was to determine how the ram body development measures relate to establishment of social hierarchy. Social rank was established using food competition test at the age of animals between 4 and 17 months. Testing was done on total of 20 male animals of which number 12 animals were selected for further testing (6 dominant and 6 submissive animals). Body mass and testicular circumferences were measured at the age of 4, 7, 12 and 18 months, and linear body measures were taken at the age of 12 and 18 months. Dominant males had higher body mass and greater testicular circumference. The social rank had no significant effect on linear body measures of rams, except for chest girth (P lt 0.05) in both control periods. Body mass was moderately to highly positively associated with studied body parameters. Significant positive correlations were established between body mass and body length (r=0.58; P lt 0.01), chest width (r=0.44; P lt 0.05), chest girth (r=0.65; P lt 0.01) and testicular circumference (r=0.62; P lt 0.01). Results obtained in this study indicate that it is justified to observe the body mass as one of the main determinants of social rank, as well as the possibility of earlier maturation of dominant animals.
AB  - Socijalni rang se odnosi na relativnu poziciju individue unutar dominantne hijerarhije koja se razvija u grupi. Kod ovnova, socijalni rang se najviše povezuje sa telesnom masom, veličinom tela i telesnom kondicijom. Međutim, iako se telesna masa generalno smatra jednom od glavnih determinanti socijalnog ranga, malo je istraživanja sprovedeno u cilju povezivanja socijalnog ponašanja i telesne razvijenosti ovih životinja. Cilj ovog istraživanja bio je da se utvrdi na koju način se mere telesne razvijenosti ovnova odnose prema uspostavljanju socijalne hijerarhije. Socijalni rang utvrđen je pomoću testa kompeticije na hranu kada su životinje bile u uzrastu od 4 i 7 meseci. Testiranje je obavljeno na ukupno 20 muških grla od čega je za dalje ispitivanje odabrano 12 grla (6 dominantnih i 6 submisivnih). Telesna masa i obim testisa mereni su u uzrastu od 4, 7, 12 i 18 meseci, a linearne telesne mere su izmerene u uzrastu od 12 i 18 meseci. Dominantna grla su imala veću telesnu masu i veći obim testisa. Socijalni rang nije imao značajan uticaj na linearne telesne mere ovnova, izuzev na meru obima grudi (P lt 0,05) u oba kontrolna perioda. Telesna masa bila je umereno do visoko pozitivno povezana sa ispitivanim telesnim parametrima. Značajne pozitivne korelacije utvrđene su između telesne mase i dužine trupa (r=0,58; P lt 0,01), širine grudi (r=0,44; P lt 0,05), obima grudi (r=0,65; P lt 0,01) i obima testisa (r=0,62; P lt 0,01). Rezultati koji proizilaze iz ove studije ukazuju na opravdanost posmatranja mase tela kao jedne od glavnih determinanti socijalnog ranga, kao i na mogućnost ranijeg sazrevanja dominantnih jedinki.

AB  - Defined geographic area with their specifity regarding unique plant species and autochthonous breeds - Sjenica and Pirot Pramenka, among traditional cheese-making practice of local community, are prerequisite for protection of denomination of geographic origin of Sjenica cheese and Pirot kachkaval. Sjenica cheese belongs to the group of soft, white cheeses in brine and it is produced as autochthonous product made of sheep milk, on the territory of Sjenica-Pester Plateau. Pirot kachkaval is firm cheese of steamed curdle produced from mix of sheep and cow milk (1:2 ratio) on the territory of Stara Planina Mountain. These are geographical areas where production takes place in village households/farms and on mountains in summer cottages (katun, bacija), which is characteristic of craft dairy processing. Specific traits of traditional manufacturing of Sjenica cheese and Pirot kachkaval derive from climatic conditions, characteristic grass associations of the specific mountain region and milk from autochthonous populations (Sjenica and Pirot sheep). In order to maintain the traditional manufacturing technology of these native products and to have organized production, it is necessary to protect the geographical origin of these products.

AB  - In this paper, the effect of different systems of crossing of sheep: two-breed (PxW) and three-breed (PxWxIDF) on production results - body weight and average daily gain of lambs weaned at the age of 60 days and fattened to age of 120 days, was investigated. Also, the effect of crossing on consumption and conversion of food and nutrients was monitored. Study was carried out on the Experimental sheep farm of the Institute for Animal Husbandry, Belgrade-Zemun, and following breeds were used in the crossing: Pirot Pramenka (P), Wurttemberg (W) and Ile de France (IDF). Pirot Pramenka was used as the maternal basis, while Wurttemberg rams were used as sires, and as terminal breed, Ile de France rams were used. Results have shown that the three-breed crosses of F1 generation, compared to two-breed crosses, obtained higher body gain for 19.23% with lower food intake for 5.19%, during fattening period lasting from 60th to 120th day of age. Regarding feed conversion ratio, they used per 1 kg of body gain 29.61% less hay and 20.82% less concentrate feeds. Positive biological effect exhibited in three-breed crosses (PxWxIDF) is consequence of individual heterosis and maternal heterosis.

Takođe su praćeni efekti ukrštanja na konzumiranje i konverziju hrane i hranljivih materija. Istraživanja su obavljena na eksperimentalnoj farmi ovaca Instituta za stočarstvo Beograd-Zemun, a za ukrštanje su korišćene sledeće rase ovaca: pirotska pramenka (P), virtemberg (W) i Il de frans (IDF). Rezultati su pokazali da su trorasni melezi u odnosu na dvorasne, u tovu od 60. do 120. dana uzrasta ostvarili za 19.23% veći prirast i za 5.19% manje konzumiranje hrane. U pogledu konverzije hrane, po kg prirasta su utrošili za 29.61% manje sena i za 20.82% manje koncentrata. Pozitivan biološki efekat koji se ispoljio kod meleza (PxWxIDF) je posledica korišćenja heterozisa individue i heterozisa majke.

AB  - Grasslands represent significant natural resource with important role in economy and ecology of every country. Properly cultivated and utilized grasslands provide cheap and high quality food for sheep, which they easily transfer into milk and meat. However, extensive management has caused degradation of pasture areas. Improvement of production of forage plants on pastures is achieved by using melioration measures, primarily fertilization. Fertilization is important also from the aspect of increase of yield and quality of forage plants. The effect of application of fertilizer depends on the present plant species in the mixture. Application of nitrogen mineral fertilizers in mixtures reduces the nitrogen fixating abilities of leguminous species, which leads to the diminishing of their competitive abilities and favouring of the grass component in the mixture. Use of excessive quantities of N fertilizer in plants causes the accumulation of nitrates, as a unfavourable quality parameter in plant tissues, which can have harmful effect on animal health. Therefore, attention should be focused on application of N fertilizers, which should be harmonized with the plant requirements, so that used quantities are not excessive and harmful. Objective of this paper is to point out the significance of fertilization as one of the most important melioration measures.

AB  - In this paper, principles of traditional production and main characteristics of Sjenica cheese and Pirot kachkaval are presented. Sjenica cheese belongs to the group of soft, white cheeses in brine and it is produced as autochthonous product made of sheep milk, on the territory of Sjenica-Pester plateau. Pirot kachkaval is firm cheese of steamed curdle produced from mix of sheep and cow milk (1: 2 ratio) on the territory of Stara Planina Mountain. These are geographical areas where production takes place in village households/farms and on mountains in summer cottages (katun, bacija), which is characteristic of craft dairy processing. Specific traits of traditional manufacturing of Sjenica cheese and Pirot kachkaval derive from climatic conditions, characteristic grass associations of the specific mountain region and milk from autochthonous populations (Sjenica and Pirot sheep). In order to maintain the traditional manufacturing technology of these native products and to have organized production, it is necessary to protect the geographical origin of these products.

AB  - The results obtained in the study of the effects of different protein sources in diet on fattening parameters, yield and quality of meat from weaned lambs are presented in this study. Experiment was conducted on 60 lambs of MIS population, weaned at the age of 60 days and divided into three groups. The effect of use of three concentrate mixtures which differed in regard to protein source: sunflower meal (I), soybean meal (II) and fish meal (III), was studied. Average daily gain of lambs on treatments I, II and III was: 0.169, 0.205 and 0.227 kg. Conversion of dry matter (kg/kg gain) on analogue treatments was: 4.54, 3.71 and 3.30; of energy (MJ NEM/kg): 33.77, 29.37 and 26.25; of total proteins (g/kg): 732, 596 and 549; of PDIN (g/kg): 502, 414 and 381; of PDIE (g/kg): 480, 425 and 396. Values of the yield of warm carcass with offal according to treatments I, II and III were: 58.70, 58.02 and 57.42%. Share of I category meat on analogue treatments was: 37.27, 37.35 and 37.51%, meat of II category: 33.9, 32.67 and 32.83%, whereas meat of III category was present in the following percentages 27.78, 29.59 and 29.10%. Surface of MLD in lambs on treatments I, II and III was: 11.47, 13.09 and 13.86 cm(2).

AB  - This paper analyzes the present state of sheep farming in Serbia and provide guidance for sustainable development in the future. It also discusses the challenges of the modern age that may affect the viability of sheep production. Today in Serbia grows less than 1.5 million sheep. In terms of breed structures, most of the population makes indigenous Pramenka sheep (80%), while the remaining 20% are: Tsigai, Merinolandschaf, Ile de France, Pirot improved, Mis sheep, and other less important population, as well as the crossbreed with foreign and local domestic sheep. However, due to the intense process of industrialization, from the second half of the twentieth century until today there is a trend of depopulation, demographic discharge of the village, which has resulted in reducing the farms so that the number of sheep in the past two decades fell by about 30%. The greatest reduction in the number of sheep registered in the nineties. After stabilization, a large decrease in the number of sheep was followed by the 2010th year and by 6% compared to 2008 year. Genetical improvement is significantly increased level of production of all species of domestic animals. However, animals selected for high and efficient production are exposed to greater risk. This primarily refers to the physiological and immunological problems, but would generally be said that all this leads to distortion of harmony between the organism and the environment and the repercussions on the molecular level. Sustainable development of sheep breeding in Serbia must be kept in mind this reality. New challenges facing the sheep breeding of Serbia, stems from a political orientation toward membership in the European Union. Sheep Serbia must find its place in this new challenge.

AB  - Results of the study of the effect of the level of nondegradable protein in diet on fattening performance and digestibility of nutrients in weaned lambs are presented in the paper. Objective of the study was to establish the optimal level of non-degradable protein in diets for weaned and intensively fattened lambs. Experiment was conducted on 60 lambs of F1 generation: Pirot Pramenka x Wurttemberg x Ile de France, weaned at the age of 60 days and divided into three groups. The effect of use of three concentrated mixtures which differed in the share of protein non-degradable at the level of rumen: 43% (I), 51% (II) and 58% (III). Average daily gain of lambs fed types of mixtures I:II:III was 0.169: 0.205 : 0.227 kg, respectively. Dry matter conversion (kg/kg of gain) on analogue treatments was: 4.54 : 3.71: 3.30, respectively, of energy (MJ NEM/kg) : 33.77: 29.37 : 26.25, and of total proteins (g/kg): 732 : 596 : 549. Level of intake of proteins was not influenced by the treatment considering that the digestibility coefficients recorded were: 52.58% : 51.30% : 55.12%. With the increase of the share of non-degradable protein in concentrate mixtures, the tendency of increase of the digestibility of fat was present: 76.13 : 77.98 : 87.17%, as well as of decrease of the intake of fibre: 67.40 : 45.87: 22.39% and NFE: 83.87 : 76.05 : 82.96%. Values of the dressing percentage of warm carcass with giblets according to nutrition types I:II:III were: 58.70 : 58.02 : 57.42%, respectively.

AB  - For the purpose of realization of the project of development of sustainable sheep production systems, in this paper, the major influences on production parameters of sheep in conditions of Stara Planina Mountain are investigated. Using the knowledge of gene effects, with good breeding programs, it is possible to realize, with more or less success, planned annual genetic progress of traits which are of interest to the breeders. This relates first of all on gain of lambs and milk yield in sheep. As already known, traits of body development and milk production vary depending on the factors of hereditary nature, but also factors of the environment. Therefore, the level of application of selection-breeding criteria is of great practical importance, which is confirmed also in this paper, and level of significance was statistically confirmed. Also, for complete creation of the program of improvement of sheep milk and meat production it is important to be aware of the effect of the breed itself, as well as of type of birth on production parameters, which was taken into consideration during investigation, processing and presentation of data in this paper. Obtained results show that majority of observed factors had significant effect on realized production of sheep.
AB  - Za razvoj održive ovčarske proizvodnje, između ostalog, neophodna je primena visokih kriterijuma selekcije i odgajivanja. Cilj ovog rada je da ukaže na praktičan značaj nivoa primene kriterijuma selekcije i odgajivanja u proizvodnji mesa i mleka ovaca u ekstenzivnom sistemu gajenja na Staroj planini. Proizvodnja mesa i mleka ovaca na Staroj planini je tradicionalna i istorijski posmatrano, uglavnom je zasnovana na gajenju pirotske pramenke, kao lokalne populacije u ekstenzivnim proizvodnim sistemima. Ova rasa kao i većina lokalnih populacija poseduje solidan genetski potencijal za prirast jagnjadi i mlečnost ovaca, ali da bi se taj potencijal ispoljio, potrebna je primena viših kriterijuma selekcije i odgajivanja, što uglavnom nije slučaj. Pored pramenke od druge polovine XX veka na području pirotskog dela Stare planine uvedena je u primenu i nova populacija-pirotska oplemenjena ovca. Ona se takođe u većini slučajeva gaji kao i pirotska pramenka, mada ove dve rase u genetskom smislu imaju veoma malo zajedničkog. Kao što je poznato, osobine telesnog razvoja i mlečnosti ovaca variraju u zavisnosti od mnogih faktora nasledne prirode ali i različitih spoljnih uticaja. Zato je nivo primene selekcijsko odgajivačkih kriterijuma, od velikog praktičnog značaja, što potvrđuju i rezultati istraživanja u ovom radu, a što je takođe i statistički potvrđeno. Pored toga za kompletno kreiranje programa unapređenja proizvodnje mesa i mleka ovaca, značajno je poznavanje uticaja same rase, kao i tipa rođenja na proizvodne parametre, o čemu se tokom istraživanja, obrade i prikazivanja dobijenih podataka vodilo posebno računa. Dobijeni rezultati istraživanja pokazuju da je većina posmatranih faktora imala značajan uticaj na ostvarenu proizvodnju. .

AB  - The main goal of this paper was to investigate the influence of some additives included into high yielding dairy cows rations to overcome the problems in early lactation. These substances directly affect the productive performances of dairy cows as well as udder health. The commercial name of investigated preparation is 'YEASTURE' and it is composed of live yeast cultures selected from three strains Saccharomyces cerevisisiae in combination with probiotic bacteria and enzymes (Lactobacillus casei, Streptococcus faecium, Aspergillus oryzae, Lactobacillus acidophilus, 1,3-b and 1,6 D-Glucan, hemicellulase, Protease, Cellulase, Alpha amylase) which have the ability to modify the fermentation in rumen stimulating the development of ruminal bacteria and increasing the fibre digestion. Effects of this preparation have been investigated on 60 Holstein-Friesian cows divided into two groups. The diets were identical, and trial group received also 10 g of preparation Yeasture daily. Application of Yeasture started 15 days prior to calving and lasted until 60th day of lactation As a research result improved in vitro disappearance of diet dry matter from roughage (alfalfa hay, maize silage and ensiled sugar beet pulp) was established. Preparation Yeasture influenced quantity and composition of the milk. The difference between trial and control group was 2.57 kg 4%FCM or 8.70% (P lt 0.01) and 7.16% milk fat (P lt 0.05).Trial group supplemented with Yeasture showed lower somatic cells count by 7.3 percent points what indicated better health of cow's udder. Based on the presented results it can be concluded that inclusion of preparation Yeasture into diets for dairy cows in transition period can be recommended.

AB  - The paper presents results of investigations of the domestic Balkan goat reared in the Sharplanina mountainous region pertaining to phenotypic correlations between the most important production traits (milk production traits for 578 goats), and growth traits of kids (for 710 kids in the suckling period). Research was done in herds of Balkan goats belonging to private farmers, during a two-year period. Simple correlation between mentioned traits were calculated using a PC and the LSMLMW program (Harvey, 1990). Data pertaining to correlation coefficients established between investigated milk production traits of the domestic Balkan goat, reflect existing correlations, which in most cases, were positive and statistically significant (P lt 0,01). Very strong correlations were established between the 1st and 2nd milk production control, as well as between the daily milk yield and the 2nd milk production control (0.796), as well as the total milk yield (0.870). Established coefficient were also statistically significant (P lt 0,01). Correlation between birth weight and the weight at specific ages (30, 60 and 90 days) were strong and very strong, while correlations between birth weight and average daily weight gain established by individual months (0.526, 0.553 and 0.384) varied between weak and strong, with an established weakening of correlations with advancing age.

Osim esencijalnih minerala, koji se redovno koriste u ishrani koza, postoji još 10 elemenata prisutnih u tragovima (mg/kg ili ppm) koji su takođe, neophodni za organizam koza, a to su: Fe, J, Cu, Zn, Mn, Co, Mo, Se, Cr, F. Pored navedenih, u tkivima koza identifikovani su još i: Al, B, Ge, Cd, As, Pb, Hg, Ru, i Nb, za koje još nije utvrđeno u kojoj su meri neophodni u organizmu koza. Njihov nedostatak u ishrani koza u velikoj meri može doprineti nižoj proizvodnji i lošem zdravstvenom stanju.",

AB  - The production of milk in a sheep breed households was 128.05 kg, with variations between 123.14 and 138.63 kg. Period of lactation was 165.04 days. Content of milk fat was 6.53%. There were significant differences in dependence of farms. Maximal daily production was in the first month of lactation. Milk yield was 1.046 kg. From the beginning till the end of lactation, milk yield was reduced for 0.479 kg, so at the end the yield was 0.567 kg. Content of milk fat at the first control was 5.30%, at the second, 6.23%, at the third, 6.98% and at the fourth control it was 7.62%. The influence was very significant on the daily production of milk.
AB  - U ovom radu prikazani su rezultati kontrole mlečnosti kod ovaca svrljiške pramenke. Istraživanje je obavljeno na šest gazdinstava i ukupno je kontrolisano 130 grla. Na osnovu dobijenih rezultata utvrđeno je trajanje laktacionog perioda od 165,04 dana. Količina proizvedenog mleka prosečno je iznosila 128,05 kg, u kojem je bilo 6,53% mlečne masti. Podaci pokazuju da postoji vrlo značajna statistička razlika (P  lt 0,01) u prinosu mleka između ovaca na gazdinstvu III u odnosu na II gazdinsitvo. Razlika je iznosila 15,49 kg ili 12,58%.

Mathematical procedures for evaluation of genetic and phenotypic parameters and anticipation of genetic values, today, are mainly based on different linear and non-linear concepts, therefore it is necessary to accept the reality that there is no absolute accuracy. Special emphasis is on the possibility of use of physiological quantitative fertility indicators in sheep selection, considering that there is correlation between them and fertility traits. In this regard, the degree of response to direct and indirect selection within population is analyzed in order to established the nature of parameters necessary for evaluation of data and determine the relative degree of such response.

AB  - Results of the investigation of the effect of the level of nondegradable protein in concentrate mixtures on digestibility of nutritive substances in fattening lambs are presented in this paper. Physiological research included 18 male lambs crosses Pirot Pramenka x Württemberg x Ile de France, average body mass of approx. 35,0 kg, divided into three groups. Lambs were fed iso-protein concentrate mixtures which differed in relation to share of protein non-degradable at the rumen level: 43% (I), 51% (II) and 58% (III). Trial results indicate that the level of protein adoption was not under the influence of investigated treatment, considering that digestibility coefficients were: 52,58% : 51,30% : 55,12%. With the increase of share of nondegradable protein in concentrate mixtures (43: 51: 58%), also tendency of increase of fat digestibility was observed: 76,13 : 77,98 : 87,17%, but decrease of degree of cellulose digestion: 67,40 : 45,87: 22,39% and NFE: 83,87 : 76,05 : 82,96%.

AB  - Knowledge about forming of sex cells, fertilization and pregnancy is basis for biotechnological effect on reproduction. Beside artificial insemination which is regularly used in practice in Serbia, embryo transfer is method which will probably have wide application, since it enables good performances of male heads and improvement with genetic material of selected female heads. Method is especially useful in selection and breeding of cattle and horses, since in previous agricultural practice, number of offspring from single female head was relatively small. At the beginning it is important to study traits of ovaries in all stages of sex cycle and isolate egg cells which could mature in vitro conditions, in adequate medium until in vitro fertilization and transfer into recipient mother.

AB  - Research was carried out on experimental sheep farm of the Institute for Animal Husbandry, Belgrade-Zemun. Trial included 60 lambs - crosses of F1 generation of Pirot Pramenka x Württemberg x Ile de France weaned at the age of 60 days. Nutrition treatment included study of three concentrated mixtures which were different in protein source (sunflower, soy bean and fish meal), i.e. share of proteins non-degradable at the level of reticulo-rumen: 43 (I) : 51 (II) : 58%(III). The effect of stated treatment in intensive fattening of lambs was monitored through production parameters. Obtained data was processed using standard statistical analysis. Average body mass of lambs at the beginning of trial, in treatments I: II: III was: 18,08: 18,12: 18,17 kg. After fattening of 75 days, final body mass of lambs in analogous treatments was: 30,78 (I) 33,52 (II) 35,17 kg (III) and average daily gain: 0,169: 0,205 : 0,227 kg. Per kilogram of realized gain of lambs, in analogous treatments, the following was consumed: 4,54 : 3,71 : 3,30 kg of dry matter of diet; energy: 33,77: 29,37 : 26,25 MJ; total proteins: 732 : 596 : 549 g. Research demonstrated that protein source in concentrate mixtures used in nutrition of fattening lambs (i.e. share of nondegradable protein in total proteins)had significant effect on production parameters, and the best performance was registered in lambs on treatment with fish meal (share of NP was 58%).

AB  - Considering that total variability of milk traits in sheep within single population greatly depends on factors of genetic nature, objective of this paper was to investigate the trend of genetics parameters in populations raised in Pirot region, in order to create more efficient selection program in regard to milk production. Obtained and processed results of investigation have demonstrated that investigated traits occupy central heritability values. Degree of heritability for protein and fat had higher values in relation to other observed traits. Weak and negative genetic correlation is present between fat content and other traits whereas strong and positive correlation was determined for milk quantity and fat content and protein. Statistical analysis confirmed absence of significant differences between sheep of Pirot Pramenka breed and improved Pirot population. This research has also demonstrated that in selection of sheep in regard to milk traits and production special attention should be directed to importance of genetic parameters considering that with the increase of quantity of milk not only content of fat but also of protein are reduced, which can influence the economical efficiency on farm in system of payments for milk according to its quality.

AB  - The system of livestock breeding as well as influence of more important factors of genetic nature on milk yield of sheep and cattle populations on the territory of Stara Planina Mountain, more specific region of the town Pirot, is analyzed in this paper. Results of the investigation have demonstrated that existing system of production can not be regarded as satisfactory, but considering the potential, it is necessary to make a great effort in order to achieve improvement of livestock production. Milkiness of sheep and cattle in this region is within the limits for specific breed however, by improving the breeding system better results could be achieved. Positive and negative genetic correlation of observed milk traits in sheep and cattle, was determined. If we accept the fact that sheep and cow milk originating from this region has specific quality traits due to the specificity of the region, and therefore essential role in production of Dojkinci hard cheese - kachkaval of Pirot type, then results obtained in this way could be indicator of more efficient application of improvement programmes in order to increase the production of milk and cheese.

Animals were fed ad libitum alfalfa hay and iso-protein mixtures (16% total protein) with different energy content. Energy value of used mixtures was 7.29 (I), 7.71 (II) and 7.94 MJ NEM (III). Trial lasted 60 days. Following production parameters were monitored: body mass, average daily gain, feed and nutrient consumption and conversion, depending on the applied feeding treatment. Statistical processing of obtained data was carried out on PC, using variance analysis. Final body masses of lambs (age of 90 days) were: 29.81 kg (I), 31.19kg (II) and 29.86 kg (III). Average daily gain for entire fattening period according to treatments I: II: III was 0.280kg: 0.303kg: 0.277kg. Values of DM conversion (kg/kg) for trial groups I:II:III were 2.68: 2.58: 2.93. Utilization of energy (MJ/kg) in average was 19.45: 18.98: 21.64, whereas the conversion of total protein (g/kg) according to the same order of treatments was 481: 451: 514. Performed research has shown that certain advantage can be attributed to lambs fed fodder mixture II (16% of total protein and 7.71 MJ NME), considering that they have realized the highest gain and the lowest use of feed and nutrients as well as energy.
AB  - U radu su prikazani rezultati uticaja različitih nivoa energije obroka na prirast i iskorišćavanje hrane i hranljivih materija jagnjadi. Ogled je izveden na 3 grupe po 20 jagnjadi sisančadi genotipa pirotska pramenka x virtemberg, uzrasta 30 dana i prosečne telesne mase oko 15 kg. Tov je trajao 60 dana, do telesne mase oko 30 kg. Jagnjad su hranjena lucerkinim senom i izoproteinskim krmnim smešama (sa 16% proteina) ali sa različitim sadržajem energije: 7.29: 7.71: 7.94 MJ NEM. Obrada podataka je urađena pomoću PC računara primenom analize varijanse. Najveći dnevni prirast (303 g) ostvarila su jagnjad koja su konzumirala krmnu smešu energetske vrednosti 7.71 MJ NEM. Konverzija suve materije (g/kg) na tretmanima I, II i III je iznosila 2680, 2580 i 2930, energije (MJ NEM /kg): 19.45, 18.97 i 21.64 i ukupnih proteina (g/kg): 481, 450 i 514.
