Abstract
Recipes of replacement calves’ diets premixes that differ from standards by the higher content of A vitamin at 18-76%, D and E vitamins - at 33%, copper - at 33%, manganese - 4 times, cobalt - at 20%, iodine - at 8%, selenium - 2,5-5 times and they influence the raise of average daily growth from 889 g to 920-960 g or at 3,5-8%. Supplementing the standard mixed forage K60-3 with high-protein forages instead of sunflower cake let us produce forages with concentration of 1,11-1,17 forage units per 1 kg or 11,3-11,4 MJ of exchange energy with 17,6-23,1% of crude protein content.

Abstract
Researches helped to determine that different kinds of voluminous forages give different productive effect in diets of calves of aftermilk phase. The greatest average daily weight gains had young calves that received hay (1046g) and green mass haylage (1053g). And usage of hay with the lowest protein degradability promoted stable weight gain raise compared to control at 6,95 % (Р < 0,05). Grass with haylage promoted stable weigh gain at 7,67% (Р < 0,05).

Abstract
A recipe of biologically active supplement “Gumelan-1” is developed and samples are prepared. It’s chemical composition is studied. Estimation of its influence in different dozes at growth and calves’ health under 3 months of age as well as at indexes reflecting reproductive system traits was carried out. More effective doze of “Gumelan-1” of 0,2 ml/kg per 1 kg of live weight was determined. The supplement promoted decrease of service-period of experimental cows at 13 days on average, decrease of insemination index at 0,7, birth of live young cattle with higher growth energy.

Abstract
Diet is developed and research set of biologically active supplement “Gumelan-1” is prepared, its chemical composition is determined. Dynamics of indexes of immune-biological homeostasis and condition of antioxidant defensive system of cows’ organism is studied at supplementing different dozes of “Gumelan-1” in period of dry-grass.

Abstract
Implementation of L-carnitine in diets of animals let them use the received with forage energy more effectively. 50 g of L-carnitine per 1 ton of mixed forage(II experimental group) and soy oil (4%) in a diet of pigs at fattening promotes increase of daily live weight gain at 3,6% (Р< 0,05), growth of meat content in carcass at 5,8% loin growth at 11,4% compared to the animals of control group. There are no definite differences on chemical composition of the longest muscle of back, fat and liver at carnitine usage stated. Studying the chemical meat composition of young pigs of the II experimental group it was stated that it differed by the lowest content of moisture (72,97%) and by the highest content of muscle fat (6,16%) that points at better mellowness and delicacy of such pork.

Abstract
Quality traits of basic components of plant origin (grain forage, cake) are studied. On nutrition and safety indexes more suitable for control fattening were barley, wheat, sunflower and soy cakes. Limits of diversity of each control quality parameter (limits, variation index, average content) and priority control indexes are determined. For barley - is natural and sprout grains, wheat - sprout grains, soy cake - urease activity (upper and lower margin), acid index, sunflower cake - acid index and crude protein content.

Abstract
Usage of microbe-ferment preparation «Axphast Gold» for cereal silage storage let us get a forage with high (70%) concentration of milk acid. Feeding with the silage influenced positively at digestibility of forages and it let us get the digestibility coefficient on the level of 59-80% or at 0,58-2,84% higher than digestibility indexes of the control silage prepared without preservatives and was on the level of “Biotroph” silage. Usage of “Biotal” preservative influences positively at usage of nitrogen, calcium and phosphorus. Also increase of volatile fatty acids was noticed in rumen of young cattle that was fed with silage preserved with «Axphast Gold» - it points on more effective usage of forage.
