Division of selection area at rest and feeding areas and setting the straw bedding norms for heifers of 6-12 months of age as 2 kg per animal daily, 13-16 months of age – 3 kg and 17-25 months of age – 4 kg promotes increases of average daily live weight gains compared to traditional technological solutions and norms at 6,4%, hemoglobin content – at 3,7%, erythrocyte quantify – at 5,6%

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

In article influence of the complex vitamin-mineral additive on natural resistance, energy of growth of newborn calves, and also definition of its optimum dose is considered. Results of dynamic changes of alive mass, hematological and biochemical indicators are resulted. As a result of the spent researches use of the complex vitamin-mineral additive in a dose 10 g on a head is offered

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

In the experiment with swine there was studied the influence of ultra-violet and various doses of narrow-band red radiation on efficiency and safety of animals. It has been established, that efficiency and safety of animal skilled groups in comparison with animals of control group has risen. Use of an ultra-violet and narrow-band red irradiation with frequency rate of inclusion of red light three times has a day allowed to raise average alive mass of young plants of pigs on 2,5 kg or on 9,1% (Р less than 0,01), a daily average gain - on 9,6%(Р less than 0,001) and safety of animals - on 10%
