本试验旨在研究饲粮添加不同水平迷迭香提取物对黑羽绿壳蛋鸡生产性能、蛋品质和抗氧化功能的影响。试验选取体重接近、22周龄种蛋鸡690羽,随机分为5个组,每组6个重复,每个重复母鸡20羽、公鸡3羽。对照组饲喂基础饲粮,4个试验组饲喂在基础饲粮中分别添加50、100、200和400 mg/kg迷迭香提取物的饲粮。试验预试期1周,正试期14周。结果表明:1)与对照组相比,饲粮添加50、200和400 mg/kg迷迭香提取物显著降低蛋鸡试验前期(23 ~ 29周龄)的平均日采食量(P

This experiment was conducted to investigate the effects of different supplemental levels of Rosmarinus officinalis extract on performance, egg quality and antioxidant function of black feather green shell laying hens. A total of 690 breeding laying hens of 22-week-old with similar body weight were randomly divided into 5 groups with 6 replicates per group and 20 hens and 3 cocks per replicate. Hens in the control group were fed a basal diet, and those in 4 experimental groups were fed the basal diet supplemented with 50, 100, 200 and 400 mg/kg...
