Results of researches are stated according to efficiency of various ways warmed pigs. It is established, that application of warmed panels allows forming more comprehensible conditions of rest for pigs. Thus within 31 days at 137,13 kw – hour or the charge of the electric power on heating of one jack of pigs is reduced to 68,48% in comparison with use of lamps of infra-red radiation without essential decrease of growth rate and safety of young growth

The research in RUP Scientific and Practical Center of Animal Breeding of National Academy of Sciences on such parameters as consumption of forages, processes of rumen digestion, morphological and biochemical structure of blood has shown that usage of wet grain preserved with Kormoplus for young cattle fattening has a positive effect on physiological condition and digestibility of nutrients and promotes nitrogen usage by animals that increases at 7,0 and 1,6%

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%

Increase of diets nutrition energy in our experiment showed no significant effect on usage of nitrogen in feeds. Diets with different energy levels have no negative effect on hematological indices of animals

There are the results of the scientific and economic experiment by the study of multifermentable supplement eniciencyin calves nutrition, it has been established that young animals with the supplementary ration by the and of the experiment have maintained the live weight on 11.4% higher compared with the control group of animals. The rate of natural phylactic power of an organism in young animals with the supplementary ration was considerably higher

In the article concept and essence of aquaponic systems for production of ecologically clean agricultural production without waste technologies is set forth. A degree of a level of studies of the given рroblem in the countries of the Europe, America, Australia and other countries is set forth too. The expediency of application of similar systems for fuller use of power resources of plants for production of heat of the electric power, an opportunity of production of agricultural production in urban conditions and on the limited ground areas is proved

The use of subcutaneous progesterone-releasing devices in superovulatory treatment allow to get high results of embryo production per donor, viability and pregnancy rates after embryo transfer in cattle. Application progesterone hypodermic inserts has allowed to lower the cost price of one received embryo on 28461 rubles

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

The present research deals with slaughter and morphological characteristics as well as physical and chemical properties of meat of young hogs taken off fattening estimated bearing relationship to back fat thickness of sow. The above data have been obtained in the commercial swine production farm specialized in three-way rotational crossbreeding in its breeding programme

In the conditions of the Agricultural Complex Belaya Rus the highest productive values of sows are obtained in period of the fourth-sixths farrowings. The highest level of reproductive traits is shown by sows of Landrace and Belorusian meaty breeds
