Estimation of efficiency of "BIOCOCKTAILE-NK" medicinal and preventive drug in broiler chickens ration

Over time, probiotics, the main component of which is E. coli, have become increasingly used in the world. To date, physiological parameters such as the state of metabolic processes and immunobiological parameters have not been studied in birds, especially when the probiotic "bio-cocktail-NK"was introduced into the diets of birds. In this regard, relevant is the use of conceptions-ons broiler chickens probiotic "Biococktail - NK", and studying its impact on the efficiency and safety of the birds. In the conditions of poultry farm "Vitkonprodukt" shumilinsky district of Vitebsk region was conducted research and production experience, in the basis of which was the assessment of the impact of the drug "Biococktail-NK" on the General, biochemical and immunological indicators of blood of broiler chickens throughout the period of their cultivation. As object of research were selected chickens-broilers cross "C0BB-500" 5-, 7-, 12-, 19-, 28-, 36- and 46 days of age. Treatment-and-prophylactic drug "Biococktail -NK" is a mixture of live Escherichia coli, the biologically active substances of the environment of cultivation and included in the composition of propolis. The application of the "Biococktail - NK" at a rate of 0.1 ml/goal. (1,0*107 micro bodies) starting from the daily age for five days in 4 cycles with an interval of 7 days until the end of the growing period allows to normalize immunological processes in the body of young birds. This result is observed due to the activation of natural resistance factors and the synthesis of immunoglobulins. As a result of the study of the blood of broiler chickens, it was established that "Biococktail - NK" has a stimulating effect on the studied indicators. According to the results of the study, BASK, phagocytosis and synthesis of immunoglobulins in the experimental group of broiler chickens was higher than in the control group; there was an increase in the amount of total protein (R), a decrease in albumin, the activity of aminotransferases and alkaline phosphatase. Also in the experimental group of broiler chickens the amount of calcium in the blood serum increased and positive dynamics of calcium-phosphorus ratio was observed. Also noted positive effect of "Biococktail - NK" in the body of broiler chickens through the stimulation of natural protective factors and normalization are most susceptible to the biochemical changes in the indicators helped to increase the safety of young animals, as in experience, which groups fell 24 heads or 2.4% and in the control of the head 64 or 6.4% (the number in the beginning of the experiment in groups was the same - 500 heads).
