日粮缺锌对猪血液生理生化指标及组织锌、铜含量的影响

Effects of ZincDeficient Ration on Biochemical and Physiological Indices and the Zn, Cu Content of Tissues in Pigs

用Ｃａ∶Ｚｎ为６０∶１、３３０∶１和５１６∶１的３种日粮分别饲喂３组仔猪１２０ｄ，对试验猪的临床症状和部分血液生理生化指标的变化进行了动态观察，并测定了试验猪１２种组织的锌、铜含量。结果表明，血液白细胞数和血清碱性磷酸酶，试验Ｂ组（Ｃａ∶Ｚｎ为５１６∶１）与对照组（Ｃａ∶Ｚｎ为６０∶１）之间有显著差异（Ｐ＜０．０５）；试验Ａ、Ｂ组猪（Ｃａ∶Ｚｎ为３３０∶１和５１６∶１）被毛锌含量、肝锌含量和肝铜锌比极显著低于对照组（Ｐ＜０．０１）。这些指标对于仔猪缺锌的早期诊断具有重要的诊断价值。

Thirty of piglets were divided randomly into three groups and fed with a ration of Ca and Zn ratio of 60∶1(control), 330∶1 or 516∶1 respectively. The duration of the experiment lasted 120 days. The clinical symptoms, some hematological and biochemical parameters were observed and analysed. The results obtained are as follows: WBC and serum AKP of the piglets fed the ration with ratio of Ca∶Zn of 516∶1 are lower than that in control group significantly (P<0.05); the contents of zinc in hair and liver of the two treated groups are significantly lower than that of the control group (P<0.01).
