| 摘 要： | 将75头体质量约20kg的“军牧1号”白猪，分成A、B、C、D、E组。A组为对照组，饲以基础日粮，B、C2组分别饲以添加122．5、250mg／kg铜(硫酸铜)的日粮；D、E2组分别饲以添加122．5、250mg／kg蛋氨酸铜的日粮，观测不同形态的铜对仔猪生长性能以及血液GH、血浆NPY水平的影响。结果显示：日粮中添加2种铜均能促进仔猪的生长，提高饲料利用率，升高血液中GH和血浆NPY水平，但对采食量没有显著影响，2种铜源在相同浓度下对猪的促生长性能无差异。

| Abstract: | Seventy-five pigs were randomly assigned into five groups,each of 15,fed on basal diets supplemented with 0,122.5,250 mg/kg copper(copper sulfate pentahydrate) and 122.5,250 mg/kg copper(copper methionine) respectively.The absolute weight(AW),average daily gain(ADG),gain feed(GF),growth hormone(GH) in serum,NPY in plasma were detected.The results as follows:High lever dietary copper(copper sulfate pentahydrate and copper methionine) increased pigs productivity and feed efficiency,but had no effect on the daily feed intake,given 122.5 mg/kg copper(copper sulfate pentahydrate and copper methionine) had the great productivity;Serum GH and plasm a NPY were elevated during the experiment;Copper sulfate pentahydrate and copper methionine at the same lever had no difference in promoting pig growth. |
