The use of oilseed processing products in compound feed for poultry and aquaculture

Abstract

Recently, the oil processing industry has been actively developing in the Lower Volga region, the by-products of which are presscake and extracted meal. The purpose of our research was to study the infl uence of feeding local non-traditional feed sources as part of compound feed on the live weight of broiler chickens and rainbow trout. Studies on broiler chickens of the cross Ross 308 were carried out at the Research Center for the safety and eff ectiveness of feed and Additives of the Volgograd State Agrarian University. The chickens of the control group received compound feed with sunfl ower presscake, and in the diet of poultry of the 1st, 2nd and 3rd experimental groups sunfl ower presscake was replaced with amaranth presscake – 50, 75 and 100 %, respectively. Scientifi c and economic experiment on the study of the possibility of including protein concentrate Gorlinka in compound feed for rainbow trout was carried out at the enterprise SO Kalmykova I. O. The fi sh of the control group received compound feed with sunfl ower extracted meal, and individuals of the 1st, 2nd and 3rd experimental groups received compound feed, in which sunfl ower extracted meal was replaced by Gorlinka concentrate – 50, 75 and 100 %, respectively, by groups. It was concluded on the base of conducted studies that the introduction of amaranth presscake into the formula of compound feed had a positive eff ect on the meat productivity of broiler chickens of the cross Ross 308. So, during the period of the experiment the live weight of poultry was increased by 2,15–5,26 %, and the slaughter yield increased to 0,29 abs.%. The use of mustard protein-containing concentrate Gorlinka in compound feed for rainbow trout contributed to the increase in the total live weight gain by 2,83–6,93 %.
