The use of biologically active substances in the feeding diets of broiler chickens
The development of meat poultry farming is impossible without the use of hybrid poultry, resource-saving industrial technology and full-fledged balanced feeding using biologically active substances in the diets. An urgent problem in poultry farming is the use of various organic acids and their salts, in particular, butyric acid, which, in the form of organic compounds with calcium and sodium, positively affects the development of the intestine, its microflora, and, accordingly, the growth and development of poultry. In the scientific and economic experiment, the productive effect of two types of butyrates, Butirex C4 and Butiplus, was compared with an input rate of 0.50 kg/t of feed. Their use in the cultivation of poultry meat direction productivity up to 50 days of age allowed to increase the slaughter weight by 3.7 %. The greatest increase in the live weight of chickens was observed up to the age of 42 days, subsequently it was identical to the control values. The use of butyrates Butirex C4 and Butiplus led to an increase in the safety of the poultry population by 2.0 and 4.0 %, respectively, and a reduction in feed consumption per unit of growth by 3.6 and 5.2 %.
