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.

肉鸡饲养中的油菜蛋糕

摘要

已经对在Habbard F-15杂交肉鸡上使用含5、10、12.5和15％菜籽饼的饲料的有效性进行了研究。这项工作的目的是建立由威廉姆斯联邦饲料生产和农业生态科学中心培育的新一代春季油菜Podmoskovny品种衍生的不同含量蛋糕的饲料在肉鸡饲料中的效率。在实验组中，每增加1公斤肉鸡活重，饲料成本降低了。饲料中加入5％和10％的菜籽饼时，主要营养成分的消化率与对照组相比没有太大差异，除了纤维，肉鸡的日平均活重增加了1.6％和2.0％。饲料中油菜饼的含量增加到12.5和15。0％导致成长中的家禽的主要动物技术和经济指标下降。建议将由威廉姆斯联邦饲料生产和农业生态科学中心培育的Podmoskovny品种的油菜籽中得到的蛋糕，以10％的重量计包括在肉鸡的配合饲料中。油菜饼的这种含量有助于使幼畜的活重增加2.0％，使饲料的利用效率增加2.7％，并使欧洲生产力指数提高22个单位。建议将由威廉姆斯联邦饲料生产和农业生态科学中心培育的Podmoskovny品种的油菜籽制成的蛋糕，以10％的重量计包括在肉鸡的配合饲料中。油菜饼的这种含量有助于使幼畜的活重增加2.0％，使饲料的利用效率增加2.7％，并使欧洲生产力指数提高22个单位。建议将由威廉姆斯联邦饲料生产和农业生态科学中心培育的Podmoskovny品种的油菜籽中得到的蛋糕，以10％的重量计包括在肉鸡的配合饲料中。油菜饼的这种含量有助于使幼畜的活重增加2.0％，使饲料的利用效率增加2.7％，并使欧洲生产力指数提高22个单位。
