PSVIII-13 Assessment of broiler chickens meat productivity

Abstract

Abstract At present, modern high-yielding crosses of broiler chickens are used to produce high-quality meat with high technological and consumer properties. To assess the meat productivity of broiler chickens grown on fodder produced in the conditions of the poultry factory at our own feed factory, a control slaughter was carried out at the age of 42 days. Analysis of the data obtained shows that with an average poultry live weight of 2000 ± 50 g, the slaughter yield of broiler chickens was 71.8 ± 0.13%. At the control slaughter, we found that the weight of the gutted carcass was 75.23%, offal 10.32%, and technical waste 14.45% (Figure 1).When studying the quantitative and qualitative composition of by-products, we found that liver accounted for 18.42%, stomachs 7.47%, heart 3.39%, neck 12.59%, legs 33.9%, heads 24.23 % by weight of offal.In the structure of technical waste feather is 24.92%, blood is 32.87%, intestine is 42.21% (Figure 3).Thus, the results of our research show that when cutting broiler chickens grown on self-made feeds under the conditions of modern poultry enterprises with a closed production cycle, gutted carcass weight is 75.23%, while legs and heads constitute the main bulk of the mass of by-products.
