Influence of different level of Camelina presscake on the quality composition of broiler chickens muscle tissue

Abstract

In Russian market of meat products production of poultry meat occupies more than 47 %. At the same time, the share of poultry products in the total volume of animal protein consumed is 42,1 %, including poultry meat – 27,8 %, eggs – 14,3 %. The quality of the resulting meat is significantly influenced by feeding (feed ingredients, biologically active additives). The purpose of the investigations was to study the influence of compound feed containing Camelina presscake on the chemical composition of broiler muscle tissue. The investigations have been carried out on the basis of the Siberian Scientific and Research Institute of Poultry Farming – a branch of the Federal State Budgetary Scientific Institution “Omsk Agricultural Research Center” (Morozovka village, Omsk region) on broiler chickens of the cross Sibiryak-2. The results of the investigations on the influence of compound feed with Camelina presscake obtained from seeds of the Siberian selection on the qualitative composition of the muscle tissue of broilers have been presented in the article. The research has been conducted on four groups of broiler chickens from 1 to 42 days of age, in each group there were 100 heads. Camelina presscake was introduced instead of another traditional protein feed to the 1st experimental group – 12,5 %, the 2nd – 15 % and the 3rd experimental group – 20 % with the preservation of the total energy and protein nutrition of the compound feed. It has been found that in the muscles of broiler chickens of the experimental groups the protein content was higher by 0,06–0,73 abs.%, fat by 0,03–0,57 abs.%, energy nutrition higher by 0,03–0,29 MJ/kg. When comparing the amount of macro- and microelements in muscle tissue, the advantage has been noted for most of the studied indicators of poultry of experimental groups that received compound feed with Camelina presscake.
