BLV exogenous oncovirus type, different from all known viruses-type mammals. Scientists around the world investigate the structure of proviral DNA, the infection is caused by BLV, an epizootic features of leukemia. To date, this is still a problem. Well understood structure of the viral genome, however only some works devoted to the influence of genotype BLV in the course of leukosis infection. Defined BLV viral load per 1000 cells in healthy animals with blood stage in the development of leukemia. The dependence of the virus’s ability to realize their lejkozogennym potency from the structure of the BLV genome.

Mikrowellentechnik in long-term experiments established that the one-time application of gypsum in solonetz cortical mnogonatsional 29 years ago on the use of phosphate fertilizers in crop rotation steam-winter rye-wheat-oats-oats leads to a dramatic deficiency of nitrogen in deep groundwater and increasing it when standing close to the surface.The supply of plants with nitrogen is very low, which requires mandatory application of nitrogen fertilizers. The best conditions of nitrogen nutrition of plants are formed by introducing gypsum in a dose of 45 t/ha. The Content easily accessible and mobile phosphorus in the casting decreases. Optimal phosphate status in the soil consists also in introducing gypsum in a dose of 45 t/ha, which remain more favorable conditions for food crops phosphorus. The introduction of increasing doses of gypsum increases the content of exchange potassium in the profile of solonetz mnogonatsional. Further finding giavanni solonetzes in deposits under the clover contributes to the accumulation of exchange potassium in the 0-20 cm layer in the soil profile. The highest efficiency one-time Deposit of gypsum in cortical mnogodetnaya saline was manifested in the land, and so long continued in subsequent deposits. With increasing duration of use of the soil in the arable land, the yield of the subsequent crop rotation (oats) in the control group increased 2.5-5 times. The highest and significant increase of productivity of crop rotation and in consequence of clover are obtained when adding gypsum in doses of 56 and 45 t/ha 49-118 % and an average of 141 and 180 %.

The results of studies of reproductive qualities of sows intra-breed type of pigs of the Duroc of Ukrainian breeding «Stepnoy» (DUSS) in terms of lines and families in conditions of JSC «Breeding plant «Stepnoy», Ukraine. It is established that indicators of multiple pregnancy and weight of the nest at weaning the sows exceed the minimum requirements of the elite class. In terms of lines, the maximum value of the complex index of reproductive qualities mentioned line of Stepnoy - 141,4 points, among sows of different families the greatest value of CIRQ had animals of families of Augusta and Romashka - by 137,2 points. Sow intra-breed type Duroc of Ukrainian breeding «Stepnoy» in its reproductive qualities dominated analogues of foreign selection.

The article describes the results of studies on the reduction of the dairy period during rearing and early introduction in the diet of bull-calves Simmental breed beet pulp and perchloric acid magnesium.

The universal mechanism for the regulation of almost all physiological functions and pathophysiological processes in animals a significant place is given antioxidant homeostasis. At the present time remains virtually unexplored level of prooxidant and antioxidant protection in cows with acute postpartum endometritis. The results of the study prooxidant and antioxidant activity of serum of cows with catarrhal purulent endometritis. Acute postpartum purulent - catarrhal endometritis accompanied by the development of oxidative stress. It is established that treatment with Emeksid helps normalize the antioxidant homeostasis.

In the course of monitoring research, arriving at the food market «Oktyabrskaya»in Novosibirsk, sea and river fish, fish and aquatic organisms we found that currently there is a tendency to reduce the supply of marine aquatic organisms (calamari, shrimp, mussels), caviar fish species, to increase the supply of oceanic (herring, mackerel, capelin) and freshwater fish (pike, carp, perch), but the assortment of fish, fish products and aquatic organisms has not changed significantly. The quality of the fish coming onto the market, fish and aquatic organisms in accordance with the requirements of normative and technical documentation.

The development of agricultural credit consumer cooperatives should be based on the mechanism of state regulation and self-regulation. In the basis of formation of the mechanism of regulation are the principles that take into account development at Federal and regional level SKPK. Shows the classification of methods of regulation of activity of rural credit cooperatives on organizational and economic. Peculiarities and specific features of development of agricultural credit consumer cooperatives in Russia has allowed to develop strategic directions for improving their operation. The regulatory system of SKPK includes key actions: development and implementation of the departmental target program for the development of agricultural credit consumer cooperatives; the allocation of regional budget funds for financial support of agriculture credit cooperatives; creation of the interregional coordination centre for the development of rural credit consumer cooperatives; strengthening the material-technical base of agricultural consumer cooperatives and development of infrastructure maintenance; the establishment of a regional guarantee and (or) pledge of funds for the cooperatives to attract additional financial resources; monitoring of the activities of the cooperatives of first level and second level; improving staffing policy, improving the educational and professional level of employees of SKPK.

Set out the three-year results of the growth regulators studies on three varieties of potatoes (Nevsky, Borodyansky, pink and Memory of Rogachev). Potatoes plants were passed all stages of development for 3-6 days earlier than in control variant, productivity increased by 17-35 %, in depending on the variety and the quality indicators of potatoes are improve (in depending on variety and growth regulator starch content increased by 0.3-1,9 % dry matter by 0,4-1,85 and vitamin C by 0.4-1.4 mg/100 g. The using of growth regulators reduced the level of nitrates in potato tubers at 6-34 mg/kg.).

For the first time at the population level, with varying degrees of compromised animals to leukemia are given (in the dynamics of recovery) changes in the qualitative composition of herds, milk production of cows, their interior indicators. It is shown that the recovery of the herd from leukosis (BLV) infection is possible to create a gene pool of cattle with higher resistance and productivity, a higher breeding qualities.

The following results of the assessment of biodiversity of wild medicinal plants on the territory of the gorge Safedchashma have been obtained. It was revealed that on the territory of the gorge there are most prevalent 50 species of medicinal plants, which are formed by representatives of 38 bloodlines belonging to 17 different families.
