FEATURES OF PRODUCTIVITY AND INTERMEDIATE EXCHANGE OF BROILERS OF PATRIOTIC AND FOREIGN CROSSES AT THE RISK OF AFLATHOSYCOSIS

Abstract

Currently, the number of potent hepatocarcinogens include aflatoxins (especially aflatoxin B1), which have a pronounced mutagenic and teratogenic effect. Their effect on the bird’s body is to suppress vital functions, such as the synthesis of protein, nucleic acids, a violation of lipid synthesis. It should be noted that genetic progress in increasing the meat production of broilers led to an increase in the intensity of metabolic processes, which in turn increased sensitivity to mycotoxins. The purpose of the study is to study the features of productivity and intermediate exchange in broilers of domestic and foreign crosses when using the formula inhibitor of toxin-nil mold in the formulation of their mixed fodders at the risk of aflatoxicosis. In this article, it was shown that at a tolerant level of aflatoxin B1, the best adaptation of the organism from broilers of foreign breeding was characterized by chickens of cross-country «Ross-308» and domestic breeding - cross «Smena-7». The results of the research showed that under the conditions of North Ossetia-Alania at the risk of aflatoxicosis, broilers of the domestic cross-country «Smena-7» and foreign «Ross-308» possessed the best economic-useful signs and the state of intermediate metabolism, which included the preparation of Toxi in the rations for detoxification of aflatoxin B1 -nil at a dosage of 2 kg / ton feed. Feeding of the approved drug contributed to the improvement of the functional activity of the liver of the foreign rosy bird Ross-308 and the domestic one - Smena-7, which, as regards control in broilers of groups II and IV, manifested itself in a significant (P> 0.95) increase in the concentration of this gland of dry substances by 0.94 and 0.98 %, of protein by 1.21 and 1.36 %, of glycogen by 10.45 and 10.52 %, and the fat content, on the contrary, was lower by 0.33 and 0.36 % (P> 0.95), respectively.
