| 摘 要： | 试验在玉米-豆饼型基础饲粮中(含锌29.2ppm)添加不同水平锌和钙研究了饲粮锌和钙水平对蛋用型鸡产蛋期生产性能、血液生化指标和组织中锌含量的影响。结果表明:1.仅喂未加锌的基础饲粮的试验鸡开产晚(P<0.05),产蛋率低(P<0.05)、蛋重小(P<0.05)、产蛋量少(P<0.01)、饲料利用效率差(P<0.01)、破壳率高(P<0.01)。饲粮加锌1000ppm与加锌40ppm对照相比,生产性能无显著差异。饲粮高钙对产蛋鸡生产性能无不良影响。2.血清碱性磷酸酶活性随饲粮加锌水平的提高而显著提高(P<0.01),但不受饲粮钙水平显著影响(P>0.05)。饲粮加锌1000ppm使血清总蛋白含量(P<0.01)、血清白蛋白和球蛋白含量(P<0.05)显著降低。饲粮高钙使血清总蛋白含量(P<0.01)和白蛋白含量(P<0.05)显著降低,而球蛋白含量不受影响(P>0.05)。3.随饲粮加锌水平的提高,肝脏(P<0.01)、胰脏(P<0.01)和胫骨(P<0.01)中锌含量大幅度升高;血液(P<0.01)、肾脏(P<0.01)和肺脏(P<0.05)中锌含量升高幅度较小;而输卵管(P>0.05)、心脏(P>0.05)和肌肉(P>0.05)中锌含量无显著变化。饲粮高钙使肝脏(P<0.05)和肌肉(P<0.01)中锌含量显著降低,对其它器官无显著影响(P>0.05)。

| Abstract: | The effects of dietary zinc and calcium level on performance, blood biochemical parameters and zinc contents in tissues of the layer were studied with corn-soy basal diet marginally deficient in zinc (=30-ppm).Performance of the layer was obviously bettered with dietary supplementation of zinc. High level of zinc ( 1000ppm) and calcium had no ill effects on performance.Serum alkaline phosphatase activity was significantly increased with the increase of dietary zinc level, but was not effected by high level of dietary calcium. Dietary zinc level had much effect on zinc contents in liver, pancreas and tibia, but had little effect in other organs. Zinc contents in liver and muscle were significantly decreased by high level of dietary calcium. |
