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.

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.

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%.

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

Application in diets of producing bulls of the increased doses of vitamins and trace elements promotes the increasing of indexes of their reproductive ability on 6,3-12,4% and natural resistance on 3,3-8,8% during the winter and summer periods, and also allows to receive profit on 1 ruble of expenses 3,7 rubles

Traditional raw materials in Belarus for mixed fodders production are wheat, barley, oats, rye, peas, lupine, sunflower and rape cakes, bran. However, productive action of these forages is limited because of presence of antinutritious factors and the raised cellulose content. In the Republic of Belarus there was organized production of national enzyme fodder additive Fekord 2004. Peculiar feature of the presented enzyme complex was addition of into its structure of enzyme glucoamylase, promoting hydrolytic starch splitting, and accordingly, the increasing of absorbency of difficult carbohydrates of forages. It was especially important for stores at early stages. Thereupon it was expedient to study the efficiency of application specified multienzyme composition in diets of growing and fattened stores. It was established, that enrichment of mixed fodder with the analysed fodder fermental additive at the rate of 0,13 and 0,15 kg per ton of mixed fodder made it possible to increase the growth rate of pigs and lower charges for forages per unit of body weight gain. Higher economic return on the fodder enzymic additive an additional gain of body weight appeared at its introduction in quantity of 0,15 kg per ton of mixed fodder

In the Republic of Belarus the grain part of mixed fodders is basically formed by the following cereal cultures: wheat (Triticum aestivum), barley (Hordeum vulgare), oat (Avena saliva) and triticale. Rye is applied in the limited quantity in pig feeding despite all its advantages: large areas of cultivation, stable yielding capacity, low requirements to growing conditions, possibility to obtain ecologically clean production, low prime cost of grain. Rye in swine diets forms viscous solutions which break digestion process, worsen their fixation and accordingly reduce animal weight gain. Also, it was determined that rye grain had high quantity of pentosans (non-starch polysaccharides) which suppress the overall digestibility and accessibility of proteins. One of the methods of decreasing the negative influence of anti-nutritional properties of rye on pig organism and improving its digestibility is the application of fodder enzyme additives. In course of the realized investigation there was analyzed the influence of foreign fodder additives on rye-containing (Sk-21 – 10% and SK-26 – 20%) diets in swine rations. The following enzyme additives were analyzed: Rovabio TM Excel (France); Finase TM (Germany); Avizyme and Porzyme 8100 TM (United Kingdom). Application of enzyme additives Avizyme, Rovabio and Finase in mixed fodders containing rye (SK-21 - 10% of rye) for pigs at the age of 50-107 days made it possible to increase live weight on 16,8-21,7% and lower expenses for forages (fodder units) per 1kg of weight gain on - 12,3-18,2%. Intensity of live weight gain from 50-day up to 190-days age was the following: in a control group -80,8 kg, in the first experimental group fed with Rovabio - 88,6 kg, in the second experimental group fed with Avizyme - 89,7 kg, in the third experimental group fed with Finase - 84,6 kg. Research results showed that enzymes Avizyme and Rovabio rendered the highest influence on mixed fodders containing rye (SK-21 - 10% of rye and SK-26 - 20% of rye)

In conditions of the Republic of Belarus much attention is given to optimization of energy and protein content in diets of dry cows. Analysis of the influence of different energy and protein ratio in dry cows diets on their productivity was realized. Increasing of protein and energy balance standards of dry cows during the winter period on 10 and 15% at the expense of introduction of protein, vitamin and mineral supplements (PVMS) made it possible to increase the daily average weight gain of animals on 5,4% and 12,2%, live weight of calves at a birth on 3,6% and 8,1% and their daily average weight gain over the first month - on 3,9% and 12,1%, respectively. Feeding with PVMS produced on the basis of peas and rape made it possible to raise the digestibility of nutritive substance on 1,4-14% and accessibility of all mineral substances on 0,4-10%. The increasing of energy and protein ratio on 15% in diets of pregnant dry cows rendered the positive effect on dairy efficiency. Fodder expenses for fodder unit production decreased on 5,5 and 6,8%, respectively. Inclusion of PVMS in mixture with pea and rape flour for dry pregnant cows during the summer period made it possible to raise their live weight on 5,9% and 9,7%, weight of calves at birth on 4,2% and 7,3%, and their daily average weight gain - on 5,7 and 9,4%. Optimization of power and protein fodder of pregnant dry cows promotes the increasing of milk yields in the first 100 days of the subsequent lactation on 5,1% and 9,9% and the decreasing of forage expenses for production unit on 4,6-9,1%

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
