| 摘 要： | 试验选用21日龄纯种大白仔猪70头，分为A、B、C、D、E5组，A组饲喂基础日粮（含铜15mg/kg)，B、C、D组在基础日粮中添加50、100、200mg/kg赖氨酸铜来源的Cu,E组在基础日粮中添加200mg/kg硫酸铜来源的Cu，试验期42d。结果表明：日粮添加不同水平的Cu可提高仔猪的日增质量，其中C、E两组与A组差异显著（P＜0．05），C组与D、E组差异不显著（P＞0．05）。与A组比较，E组十二指肠内容物脂肪酶活性显著提高（P＜0．05）。B、C、D组十二指肠、胰脏脂肪酶活性有提高趋势，但差异不显著（P＞0．05）。

| Abstract: | Seventy Yorkshire weanling pigs (average initial mass of 5.4 kg and age of 21 d) were randomLy assigned into five groups. The diet treatments were 0(15 mg/kg of Cu in basic diet), 50, 100, 200 mg/kg of supplement Cu from Culys or 200 mg/kg of supplement Cu from copper sulfate (CuSO 4).The experiment period was 42 d. Average daily gain increased linearly ( P <0 05) with increasing dietary level of Cu, with no difference among 100 mg/kg of supplement Cu from Culys, 200 mg/kg of supplement Cu from Culys or CuSO 4 ( P >0 05). The addition of 200 mg/kg of supplement Cu from CuSO 4 stimulated duodenum lipase activity ( P <0 05), but with no effect ( P >0 05) on pancreas lipase activity. The addition of different level of supplement Cu from Culys improved duodenum lipase activity but the difference was not significant ( P >0 05). The result showed that Culys is an excellent Cu rsource, lower doses of Culys could get the same effect as higher doses of CuSO 4. |
