| 摘 要： | 为了研究饲粮中添加蛋氨酸铜与硫酸铜对生长猪生长性能、养分消化率、血清铜锌含量及粪铜锌排泄量的影响。选择体重为17．17±2．34kg（P〉0．05）的二元杂交（长×大）生长阉公猪30头进行试验，试猪按完全随机区组设计，依体重和窝别随机分为5个处理，每个处理3个重复，每个重复2头猪，分别饲喂10、150、250mg／kg蛋氨酸铜和150、250mg／kg硫酸铜，试验期30d。结果表明：饲喂蛋氨酸铜组ADG、F／G及表观养分消化率具有明显的优势；血清铜含量随饲粮铜水平的提高而发生显著变化，而高铜组组间血清锌差异不显著；蛋氨酸组粪铜排泄量比硫酸铜组粪铜排泄量显著降低。说明：添加中等水平的有机蛋氨酸铜吸收利用率比高剂量硫酸铜高，且可减少粪铜、锌的排泄。

| Abstract: | To investigate the effect of diets supplemented CuMet and copper sulfate on growth per-formance, apparent digestibility of feed nutrients, serum copper zinc content and fecal copper zinc excretion in pigs, 30 two-line crossbred （Landrace × Yorkshire） were selected according to a randomized complete block design,and divided into 5 groups, each group of 3 repetitions,each duplicates 2 pigs separately fed with 10mg/kg, 150mg/kg and 250mg/kg copper from CuMet,and 150mg/kg ,250mg/kg copper from copper sulfate diets. The results showed that the ADG,F/G and apparant digestibility of feed nutrients of CuMet group has obvious superiority; the copper content of blood serum changes with the increase of copper level in the diet, but the zinc content of blood serum in high copper group differ insignificantly; the fecal copper excretion in Cumet group decreased significantly than that in the copper sulfate group. Diets supple-mented with the medium level organic CuMet has higher absorption rate than that with copper sulfate,and which can reduce the excretion of fecal copper and zinc. |
