Abstract
Studies have been conducted on the effectiveness of using feed containing 5, 10, 12.5, and 15% rapeseed cake on broiler chickens of the Habbard F-15 cross. The aim of this work was to establish the efficiency of feed with different levels of cake derived from the Podmoskovny variety of spring rapeseed of a new generation bred by the Williams Federal Scientific Center for Fodder Production and Agroecology in feeding of broiler chickens. Feed costs per 1 kg of live weight gain of broilers in the experimental groups were reduced. The digestibility of the main nutrients when 5 and 10% rapeseed cake was included in the feed compared with the control did not differ much, except for fiber, and the average daily increase in live weight of broiler chickens increased by 1.6 and 2.0%. An increase in the content of rapeseed cake in the feed to 12.5 and 15.0% led to a decrease in the main zootechnical and economic indicators for growing young poultry. It is recommended to include the cake obtained from the Podmoskovny variety of rapeseed bred by the Williams Federal Scientific Center for Fodder Production and Agroecology in the compound feed for broiler chickens in an amount of 10% by weight. This content of rapeseed cake contributes to an increase in the live weight of young animals by 2.0%, an increase in the efficiency of feed use by 2.7%, and an increase in the European productivity index by 22 units.
