Immunodeficiency states quite common. Gipoglobulinemiya occurs in 60% of animals tested, indicating a low immune status. Low levels of circulating immune complexes and immunoglobulins in calves born with gipoglobulinovym immunosuppression indicates status of the immune system.

The article reveals the problems of diseases of young cattle that occur during adaptation at different technologies of cultivation, in particular for group, individual and cellular content when grown under conditions of low controlled temperatures.

The decisive condition for exit from the crisis of agriculture in modern conditions is to increase competitiveness. The article examines the factors influencing the competitiveness of agricultural products. The analysis of the competitive advantages of the agricultural enterprises. Proposed key factors contributing to the increase of competitiveness.

The biological and economic efficiency of herbicides and their tank mixtures with baktofitom on spring wheat. Contribution antidepressant increase in grain ranges from 13.5 to 35.5%, the level of profitability of grain production amounted to 51.4%.

It developed and implemented a health program for bovine leukemia obtained by the group bioassays.

A study of the blood of cattle imported from abroad. Are considered indicators of changes in the morphological, immunological and biochemical parameters in cows in the initial period of adaptation to the new conditions.

The results of evaluation of milk and meat from an infected patient and leukemia cattle. These organoleptic, microbiological and physico-chemical indicators confirm the difference in the quality of products from animals with different degrees of compromise to leukemia. For a number of indicators of meat and milk of animals suffering from leukemia is comparable to similar products of poor quality or stale. According to the results of physico-chemical studies found that with an increase in the shelf life of the pH of meat from sick animals increased to 6.5 after 96 hours of storage, and benzidine test shows a positive reaction. Organoleptic animal milk in the stage of asymptomatic infections are comparable to those in healthy persons. Cows infected and hematological patients with leukemia, increased the amount of fat in milk, reduced protein content, reduced titratable acidity. Bacterial contamination of milk cows hematological patients higher than those infected and healthy.

A comparative study of the chemical composition of native dung in different species of farm animals. His influence on the ecological environment of the organism.

The negative impact of environmental factors affect the body of the animal. In the zones of ecological trouble, the animals have significant antigenic load (radiation, xenobiotics, etc.) and, consequently, a larger amount of immune complexes formed with large critical mass of antigens. namely indicators of circulating immune complexes in the blood serum may be integral test determining the degree of antigenic nature.
