METHOD OF INCREASING THE PRODUCTIVITY OF BROILER CHICKENS THROUGH THE USE OF FUNCTIONAL ADDITIVE

abstract 1211607120 issue 121 pp. 1897 – 1906 30.09.2016 ru 465
In the experimental work, we studied the effect of the inulin prebiotic on the growth, development and efficiency of growing broiler chickens of the Isa cross. In accordance with the scheme of the experiment, the first control group was fed a complete feed (CF) by periods of growth. In the second group, inulin was added to the CF for the first 21 days of growth. In the third group prebiotic was added to the CF at the same rate throughout the whole period of rearing the chicks (42 days). In the second and third groups, we found the tendency to increase the intensity of growth rate in poultry by 1.6 and 3.0%, respectively, compared with the control. Feed costs for weight gain were decreased by 2.1-2.7%. In the chime of the blind processes of the intestine of the chickens of 2-3 experimental groups it was found the reduction of staphylococci and enterococci CFU, while similar to the control group lactobacilli CFU. The muscle tissue in the chickens of experimental groups had greater protein content. The optimal range of indicators is the use of inulin for the first 21 days of rearing poultry. Because of the production audit, an increase in live weight of chickens was found, in the experimental group by 2.7% (p ≤ 0.05), a decrease of feed costs by 7.5%, increase of the survival rate of poultry by 2.0% and profitability by 3.1%
