为研究饲粮中添加无机锌和有机锌对雏鸡生长和免疫功能的影响，对700 ~ 800只肉鸡（0 ~ 28日龄）进行了连续3次试验。试验选用基础饲粮（锌含量为72 mg /kg）和基础饲粮（锌含量为152 mg /kg）中添加氧化锌或有机锌-蛋氨酸的4只栏式育雏鸡。分别饲喂不添加Zn （100 mg Zn/kg）或添加Zn （40 mg/kg）的饲粮，其中ZnO和DL-Met或Zn- met的添加量为140 mg Zn/kg。饲料系数和平均体重在各处理间无显著差异（P < 0.05）。饲粮中添加锌-蛋氨酸可提高(P
Three consecutive trials involving approximately 700 to 800 broilers (0 to 28 days) were conducted to examine effects on growth and immunity of chicks after supplementing dams with inorganic Zn versus organic Zn. Offspring from hens fed a basal diet (72 mg Zn/kg) or diets with 152 mg Zn/kg supplemented with ZnO or organic Zn-Met were randomized across four battery brooders. Chicks were fed a starter diet without supplemental Zn containing 100 mg Zn/kg or diets supplemented with 40 mg/kg Zn from ZnO and DL-Met or Zn-Met containing 140 mg Zn/kg. No differences among treatments (P >.05) were found in feed conversion or average BW. Supplemental Zn-Met in hen diet increased (P
