本试验旨在研究不同锌源和水平对断奶仔猪生长性能及血清、粪中锌含量的影响.锌源为2种新型氧化锌,分别是以包合技术制成的包合分子氧化锌和以硬脂酸包被的氧化锌.选取250头24日龄平均体重为(6.74±0.35) kg的"杜×长×大"断奶仔猪,随机分为5组,每组5个重复,每个重复10头猪(公母各1／2) . 5 组分别为对照组(基础饲粮+2 250 mg／kg普通氧化锌,以锌计,下同) 、包合分子氧化锌300组(基础饲粮+300 mg／kg包合分子氧化锌) 、包合分子氧化锌600 组(基础饲粮+600 mg／kg 包合分子氧化锌) 、包被氧化锌 300 组(基础饲粮+300 mg／kg包被氧化锌) 、包被氧化锌600组(基础饲粮+600 mg／kg包被氧化锌) .预试期...

The purpose of this experiment was to study the effects of different zinc sources and levels on growth performance and content of zinc in serum and feces of weaned piglets. Two new types of zinc oxide were the inclusion molecular zinc oxide which made by inclusion technology and the zinc oxide which coated with stearic acid. A total of 250 twenty?four?day?old " Duroc×Langdrance×Large White" weaned piglets with body weight of (6.74±0.35) kg were randomly divided into 5 groups: control group ( basic diet+2 250 mg／kg normal oxidation zinc, as ...
