本试验旨在研究不同水平有机复合微量元素替代无机微量元素对1 ~ 42日龄樱桃谷肉鸭生长性能、屠宰性能、血清抗氧化和免疫指标以及粪便中铜、铁、锰和锌含量的影响,以确定有机微量元素在肉鸭饲粮中的适宜添加量。试验选择525羽1日龄健康樱桃谷肉鸭,随机分为5个组,每组7个重复,每个重复15羽。对照组饲粮(100%无机组)以无机盐形式按推荐量100%提供微量元素,4个有机组饲粮分别以推荐量的25%、50%、75%和100%添加羟基蛋氨酸螯合形式的铜、铁、锰和锌。试验期42 d。饲粮分为2个阶段(前期1 ~ 21日龄和后期22 ~ 42日龄)配制,各组除铜、铁、锰和锌外,其他营养水平均保持一致。结果表明:1)各组肉鸭各阶段...

This experiment was conducted to investigate the effects of different levels of organic complex trace elements replacing inorganic trace elements on growth performance, slaughter performance, serum antioxidant and immune indices, and fecal copper, iron, manganese and zinc contents of Cherry Valley ducks from 1 to 42 days of age, so as to determine the appropriate supplemental level of organic trace elements in diets for meat ducks. A total of 525 healthy Cherry Valley ducks of 1⁃day⁃old were randomly divided into 5 groups with 7 replicates pe...
