Results of researches on studying influence separate and combination feeding fermented compositions Fekord-2004C and biologically active additive Oxide Peat on energy of growth and protective properties of an organism of pigs – deprivation are stated. It is established that enrichment of mixed fodder investigated by the fodder fermented additive Fekord-2004C at the rate of 0,15 kg on ton of mixed fodder in combination application with biologically active substance Oxide Peat in a doze of 1,0 kg on ton of mixed fodder promotes increase of growth rate of pigs on development and to decrease of the charge of forages on unit of a gain of alive weight and safety of pigs

In the physiological experience spent on male pigs-manufacturers, we had been studied influence of various doses of selenium (10 mg, 20 and 30 mg) in structure premix on nutrients. It is established, that increase of level of selenium in mixed fodders for male pigs-manufacturers to 30 mg/kg especially promotes increase in degree of use in their organism of fat to 58,7%; (P less than 0,05), the digested nitrogen to 62,1%, calcium – to 78,3% and phosphorus – to 72,5%

The recipe of mixed fodder is developed for cows with a 6-8 thousand kg yield of milk for a lactation during the period yield of milk, different the raised maintenance of a crude protein (18%) that allows to increase a yield of milk of animals by 6,6% (22,5 kg instead of 21,1 kg of 4% milk a day) to reduce the expense of forages on production unit to 6,4% (0,73 fodder units against 0,78 fodder units per 1 kg of milk). At the expense of additional production economic benefit makes 104,4 thousand rbl. counting on 1 head

Balancing of mixed feeds for replacement gilts considering the metabolically energy level and essential available amino acids amount increases growth speed of animals at 9,6% (P less than 0,05) compared to mixed feeds prepared in correspondence with detailed norms of feeding; it also decreases terms of animals pedigree usage from 277 to 223 days
