In this study five samples each of serum glucose, serum cholesterol and uric acid contents were measured in Fayoumi, Rhode Island Red, Parent desi, desi Fl and desi F2 strains of chickens. Cholesterol contents were found to be lowest in desi F2 chickens whereas in other strains there was least significant difference, which can be attributed to reduced lipogenic activity in desi F2 generation. When five samples each of meat from two locations i.e. breast and thigh was subjected to proximate analysis it was found that there was no difference (P greater than 0.05) in crude protein, crude fat, total ash and moisture contents regardless of sex and strains. Dry matter contents differed (P less than 0.05) in breast meat and found to be lowest in Parent desi stocks.

A study was conducted to evaluate the biomass yield and proximate composition of biomass from the natural pastures of Madras Red sheep. Eight villages were selected from the habitat of Madras Red sheep and 40 samples each during  rainy and summer season were collected to assess the biomass yield and proximate composition. The study showed that biomass yield and proximate composition were higher during the rainy season during which these sheep completed their breeding, reproduction and lactation. The total dry matter content was higher during the summer season which was able to meet maintenance requirement of sheep during these months. Farmers managed these animals without any supplementary feeding, but during summer the animals were let in the harvested fields where they had access to crop residues for grazing.

A total of sixteen commonly available medicinal herbs (different parts) used in Indian traditional medicine were collected. The collected parts were, shade-dried, ground to fine powder and stored in air-tight containers. The samples were analyzed for proximate principles, acid-insoluble ash, gross energy, minerals and fatty acids. Emblica officinalis fruits had significantly (P < 0.05) highest moisture (88.67%), Moringa oleifera leaves had significantly (P < 0.05) highest crude protein (26.99 %), Coriandrum sativum seeds had significantly (P < 0.05) highest crude fibre (32.53%), Syzygium aromaticum buds had significantly (P < 0.05) highest crude fat (18.57 %), Mentha spicata leaves had significantly (P < 0.05) highest total ash (11.53 %), Allium sativum bulbs had significantly (P < 0.05) highest nitrogen-free extracts (90.14 %) and Murraya koenigii leaves had significantly (P< 0.05) highest acid insoluble ash (4.71 %). The gross energy content was significantly (P < 0.05) highest in Coriandrum sativum seeds (4605.33 Kcal/Kg). Azadirachta indica leaves had significantly (P < 0.05) highest calcium (2.99 %), Phyllanthus niruri leaves had significantly highest (P < 0.05) phosphorus (0.53 %), Andrographis paniculata stem and leaves had significantly (P < 0.05) highest copper (41.27 ppm), E. officinalis fruits had significantly (P < 0.05) highest iron (596.78 ppm) and S. aromaticum buds had significantly (P < 0.05) highest manganese (286.96 ppm). C. sativum seeds had significantly (P < 0.05) highest levels of oleic acid (73.76 %), T. foenum seeds had significantly (P < 0.05) highest levels of linoleic acid (36.43 %) and P. niruri leaves had the significantly (P < 0.05) highest levels of linolenic acid (51.78 %) Further studies are needed to quantify other bioactive compounds, to study their antioxidant and antimicrobial properties so that they could be used as alternatives to antibiotics / other drugs for livestock and poultry.

Using macro and microelements, vitamins A and D in correspondence with norms of Institute of Animal Husbandry (1992) per 1 kg of dry substance of a diet: phosphorus - 5,29 g, calcium - 7,46, sodium - 5,59 g, copper - 12,64 mg, zinc - 77,26, magnesium - 77,26, vitamins A and D correspondingly - 23,74 and 1,02 thousand ME for highly productive lactating cows with average daily milk yield of 32 kg at summer feeding compared to Agricultural Academy norms (1985) promotes increase of the so called relative products outcome and profit from basic fatness (3,4%) milk sale per 1 animal at 411 rubles

Belarus is included into number of the leading countries of the world which provide the increasing of the expansion rates of milk production and dairy products on a per capita basis. However, the agricultural enterprises of the Republic of Belarus annually spend approximately 800 thousand tons of whole milk that makes about 20% from the general milk yield for manufacturing expenditures in the process of livestock operation. The purpose of research was working out of a new premix structure and zootechnic requirements to its use in structure of milk replacer, produced on hydrodynamic installation. The optimum doses of amino acids, vitamins and mineral substances promoted the increasing of calves daily average weight gain during the dairy period on 5,4% (788,5 g instead of 748,1 g), reducing of expenses for forages per 1 kg of weight gain - on 6,5% (2,9 fodder units against 3,1 fodder units) and the decreasing of the prime cost production for fodder expenses - on 4,7%. There was presented the composition and nutritive value of the analysed whole milk replacer. Usage of local sources of protein-fatty raw materials of plant origin, and also secondary resources of processing of whole milk in the content of milk replacer for young cattle allows to completely refuse from expensive components delivered from abroad and to lower their cost

Application zoned bare-grained oats grades in a diet of chickens and hens-layers of egg breeds makes positive impact on efficiency of a bird, forage conversion, reduces expenses of forages for manufacture of eggs that allows to receive additional profit. The maximum norm – 40 % bare-grained oats in mixed fodders of hens is defined

Feeding replacement heifers of 6-12 months of age with mixed feed that contains 20-25% of rape and lupine grain within winter and summer diets instead of sunflower cake allows to obtain the average daily weight gain of 893-927 g at forage spends of 6,0-6,3 с of forage units. The cost of these mixed feeds is decreased at 14% and prime cost of 1 c of weigh gain-at 6-15%

In the conditions of application of enzyme preparations there is the possibility of inclusion into mixed fodders structure of such cheap fodder grains as rye. Determination of the optimal dose of introduction of the liquid enzymatic fodder additive (xylanase – 8800 units; phytase – 600 units; cellulose – 880 units; r-gluco – 4000 units; a- amylase – 200 units) and its influence on stores productivity during the completion of growing and fattening periods was realized in the conditions of the Republic of Belarus. Research results showed the following: inclusion into mixed fodders of the increased amount of rye grain (without the enzyme additive) for stores feeding during the completion of growing (20%) and fattening (30%) periods did not render negative influence on experimental animals; the optimal dose of the trial enzyme for stores during the completion of growing period - (SK-21 including rye grain - 20%) was 200 ml per 1 t of mixed fodders; the optimal dose of the trial enzyme for stores during the fattening period (KDS-26 including rye -30%) was 150 ml per 1 t of mixed fodders. Application of the experimental fodder additive promoted the increasing live weight gain. There was noted the tendency of the positive influence of the analyzed enzyme on dry and organic matter, fat, dietary fibre and nitrogen-free extractive substances digestibility

In process of animal husbandry intensification much attention should be given to maintenance of the high-grade balanced feed of animals. Forage supplement Profat (Protected Fat) is a protected fat in dry-sand mould with 84% of fat content. Application of 0,5-0,8 kg of dry fat supplement in cows diets per 1 head a day (4,7-10,0% in mixed forage content) promotes the increasing of prime cost of milk yield with basic fatness at 1,8-2,8% within fatness growth at 0,1-0,24% without protein content decrease. During the analysis of morphological and biochemical blood structure there was not established any considerable inter-group distinctions. At the same time, it is necessary to notice, that in blood of animals of two experimental groups there was stated a little bit higher protein content. However, in proportion to application of experimental fat additive up to 0,8 kg per head a day the protein content decreased. The increased number of erythrocytes and hemoglobin content in blood of animal of trial groups proved the strengthening of metabolic processes. In blood of trial groups it was noted high quantity of vitamin A and phosphorus as well as lower amount of calcium

In the conditions of the Republic of Belarus there was analyzed the efficiency of feeding of a new protein vitamin and mineral additive containing national local protein and mineral raw material sources in diets of 12-16-month old heifers. Instead of sunflower extraction cake the heifers were fed with the protein-vitamin and mineral additive which contained rape grain (Brassica napus), lupine (Lupinus) grain as well as mineral and vitamin additives based on halites, phosphogypsum, phosphate, sapropel and premix in dose of 20-25% by weight as a part of mixed fodders. The additive was used against the background of rations with green mass from a cereal and leguminous mixture - 56-57%, mixed fodder - 36-37%, molasses - 6-7%. In accordance with nutritional value indexes the proposed additive rendered the positive influence on forage consumption, indexes of ruminal digestion, as well as on the morphological and biochemical blood composition. It application made it possible to obtain daily average weight gains of animals at the level of 812-827 grams within forage expenses of 7,0-7,2 сentner of fodder units. Inclusion of the protein vitamin and mineral additive with local protein and mineral raw materials in rations of calves made it possible to lower the mixed fodder cost price on 12-15% and the cost price of 1 centner of gain during the summer period - on 11-13%.
