CHANGES OF BIOLOGICAL VALUATION MEAT OF BROILER CHICKENS UNDER THE INFLUENCE OF GAMMA-HCH
Journal Title: Наукові доповіді НУБіП України - Year 2017, Vol 4, Issue 4
Abstract
The data on the amino acid composition of white and red muscles of broiler chickens are provided, provided that gamma-HCH is supplied with the pesticide feed. It has been established that gamma-HCH is negatively affecting the biological value of both the red and white muscles of broiler chickens. The presence of gamma-HCH in feed for chickens-broilers at doses of 0.1 (the first test group) and 0.3 mg / kg of feed (the second research group) (MGS) changes the amino acid composition of meat. In the white muscles of broiler chickens of the first test group, the content of interchangeable amino acids was 3.38%, and the second - 6.2% lower than in the muscles of the bird in the control group. In red muscles, this indicator was lower by 5.8% in the first test group and by 11.6% in the second, compared with the control group. Reducing the levels of amino acids in the white and red muscles of broiler chickens is directly proportional to the increase in dose. In the second test group, the valine, isoleucine, leucine and lysine values in red muscle fibers were significantly reduced. On the contrary, the downward trend was less rapid in methionine, threonine, phenylalanine and tryptophan in white muscle fibers.
