AB  - This paper presents heat consumption optimization and possibility to increase energy efficiency of Belgrade residential buildings. Residential buildings were selected according to the year of construction and type of building (multi apartment buildings and single family houses). Numerical simulation was applied to investigate heat consumption of buildings' zero model which represents buildings' current state. Numerical simulations were performed for typical meteorological year conditions for Belgrade city area. In this calculation, building surroundings, outside heat transfer coefficient (which depends on local weather conditions) and inside heat transfer coefficient (according to the type of walls) were taken in account. The validation of zero model is based on measured and calculated inside air temperature in considered objects. The influence of improved building envelope on heat consumption, compared to building zero model, was investigated by adding insulation and/or by replacement existing windows with those with better thermal characteristics. The energy consumption was numerically simulated over whole heating season. The energy efficiency increase calculations showed possibility for saving heating energy from 10% to 80%. This conclusion was obtained by comparing four different scenarios of improved building envelope with basic zero model for four modeling objects (two multi apartment buildings and two single family houses). Results indicate that focus of energy savings should be on how to decrease energy consumption in households sector. Additionally, solar energy use for two different objects (PV cells were applied for multi apartment building and solar thermal collectors for single family house) was numerically simulated.

AB  - The objective of this research was to study the effects that the extract of rhizome and root of Helleborus odorus W. et K. (Ranunculaceae) can have on modifications in the parameter values of white blood cells count and degree of phagocytosis by peritoneal macrophages and neutrophil granulocytes in Wistar rats. The trial was conducted on 28 rats divided into 4 groups with 7 animals in each group. To the control group of rats sterile physiological solution in the quantity of 0.25 mL/100 g BW was applied intramuscularly. For the purpose of monitoring the effect of the extract of rhizome and root of hellebore (HE) during a time period, the HE was applied intramuscularly to rats in a dose of 10 mg/100 g BW, while the blood samples for analysis were taken after 24h, 48h and 72h. The consequence of intramuscular application of HE was an increased count of total leukocytes in all trial groups, the most expressed leukocytosis being registered 24h after application of HE. Statistically significant higher value in the count and percent of neutrophil granulocytes in the blood was recorded 24h after treatment in relation to the control and two other trial groups (p lt 0.001), among which a statistical significance was not established. The extract of hellebore rhizome and root has led to lymphopenia, resulting in the increase of the neutrophil/limphocyte index in the trial groups 24h and 48h after treatment. The application of HE had no significant effect on the count of monocytes in treated animals. The applied extract has caused a significant increase in the degree of phagocytosis by residing peritoneal macrophages and neutrophil granulocytes in blood.
AB  - Cilj ovog rada je bio da se ispita uticaj ekstrakta rizoma i korena H. odorus W. et K. na promenu vrednosti parametara bele krvne slike i stepen fagocitoze od strane peritonealnih makrofaga i neutrofilnih granulocita kod pacova soja Wistar. Ogled je izveden na 28 pacova podeljenih u 4 grupe po 7 jedinki. Kontrolnoj grupi pacova je intramuskularno aplikovan sterilan fiziološki rastvor u količini od 0,25 ml/100 g TM. U cilju praćenja efekta ekstrakta rizoma i korena kukureka (EK) u toku vremena, pacovima je intramuskularno aplikovan EK u dozi od 10mg/100g TM, a krv za analizu je uzimana posle 24h, 48h i 72h. Intramuskularna aplikacija EK imala je za posledicu povećanje broja ukupnih leukocita u svim oglednim grupama, pri čemu je najizraženija leukocitoza registrovana 24h nakon aplikovanja EK. Statistički značajno veća vrednost broja i procenta neutrofilnih granulocita u krvi zabeležena je 24h posle tretmana u odnosu na kontrolnu i ostale dve ogledne grupe (p lt 0,001), između kojih nije utvrđena statistička značajnost. Ekstrakt rizoma i korena kukureka doveo je do nastanka limfopenije, što je imalo za posledicu povećanje neutrofilno/limfocitnog indeksa u oglednim grupama 24h i 48h nakon tretmana. Aplikacija EK nije značajno uticala na broj monocita kod tretiranih životinja. Upotrebljeni ekstrakt doveo je do značajnog povećanja stepena fagocitoze od strane rezidentnih peritonealnih makrofaga i neutrofilnih granulocita krvi.

AB  - The aim of this study was to estimate the association between body condition and fatty liver in high-yielding dairy cows. One hundred dry Holstein cows were selected. Cows were scored once for body condition during the dry period, puerperium and month 2 of lactation, according to the system provided by Elanco Animal Health Buletin Al 8478. Body condition loss was determined as marked if loss was over 0.7 points between two consecutive phases of cycles and over 1.5 points between puerperium and month 2 of lactation. Liver tissue samples were taken 12 d after calving and tested for lipid content. 50% of cows had mild (3.92 +/- 3.33% fat), 33% moderate (19.28 +/- 5.18% fat), and 17% severe fatty liver (36.21 +/- 4.55% fat). The mean body condition scores were 3.79 +/- 0.55 (dry period), 3.18 +/- 0.34 (puerperium) and 2.90 +/- 0.29 (month 2 of lactation). Marked body condition loss from the dry period to puerperium had 38% of cows, 20% from dry period to month 2 of lactation and 8% from puerperium to month 2 of lactation. Body condition scores out of the physiological range had 39% dry cows, 49 % cows in puerperium and 9% cows at month 2 of lactation. After dividing cows into groups according to fatty liver degree, it was shown that only cows with severe fatty liver were obese during the dry period and that 76.47% of cows from this group had marked condition loss from the dry period to puerperium, 47.06% from dry period to month 2 of lactation and 23.53% from puerperium to month 2 of lactation. These indicate that in cows with severe fatty liver lipomobilisation is intensive and starts around calving, before milk production enhacement. Our results indicate a strong association between body condition and fatty liver in cows, which can be estimated only when body condition is analyzed in details. Besides, our results clearly indicate that body condition is not the only etiological factor that leads to fatty liver in dairy cows.

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.
AB  - Ogled je izveden na 260 pilića Hybro provenijence podeljenih u 13 grupa, u trajanju od 6 nedelja. Sve grupe pilića hranjene su komercijalnim smešama, a selen je dodavan u hranu u formi natrijum selenita ili seleniziranog kvasca u količini od 0, 2, 5, 10, 15, 20 ili 30 mg/kg. 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.

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  - Agriculture is one of the crucial development areas and, together with tourism, it presents the top priority for the economic development of Montenegro. The most important branch of agriculture is livestock raising. Livestock development is particularly crucial because the rearing of ruminants (cattle, sheep, goats) utilizes the less productive land lots (pastures, meadows) which present over 80% of the total agricultural land in Montenegro. In terms of the size and value of production, the most important area of livestock development is cattle raising. A significant place is also held by sheep - raising, especially in the context of unpolluted pastures which represent favorable conditions for the production of biologically valuable food. In terms of the ratio of primary production, livestock raising participates with 64,4%, and fish and bees are added to this calculation the percentage is 65%. The analytical data for 1995-2001 demonstrates that there is a growth of 3-4%in the cattle-raising industry whereas sheep-raising has demonstrated a fall since 1998. Out of the total number of cattle and sheep 99% is in private ownership, and only 1% is in public ownership. The production of cow s milk recorded a growth, whereas the production of sheep milk has been fluctuating. There is recorded growth in beef production of 3-4%, where as there is a noted fall in the production of mutton. The local milk production secures 88% of the total consumption whereas the production of meat (the consumption is 45,1 kg per capitas) secures only 61% of total consuotion. The production of poultry and pork covers only 40% of consumption. This paper also gives an overview of the consumption of mutton and how this relates to figures of local production for the period 2001.- 2002. For successful livestock development in the hills and highlands of Montenegro, apart from measures taken to improve the genetic base, it is necessary to undertake measures to improve animal diets health protection and healthcare as well as the application of newer biotechnologies.
