| 摘 要： | 试验研究高温下 (32℃ )不同维生素A(VA)添加水平 (30 0 0IU/kg和 90 0 0IU/kg)对蛋鸡的生产性能、某些血液生化指标和免疫性能的影响。结果表明 ,高温下不同VA添加水平对蛋鸡的采食量 (P <0 .0 5 )、产蛋率 (P <0 .0 5 )、血糖 (P <0 .0 1)有显著影响 ,但对料蛋比、蛋壳厚度、蛋重、尿酸、抗体水平无显著影响 (P >0 .0 5 )。

| Abstract: | The effects of different vitamin A levels(3 000 IU/kg, 9 000 IU/kg) on laying performence, some blood biocheminstry indices and immune function of laying hens under high temperature(32 ℃) were investigated. The results indicated that VA levels had significant effects on feed intake(P<0.05), laying rate(P<0.05) and serum glucose(P<0.01), but no significant effects on the rate of feed and egg, shell thickness, egg weight, serum urea acid and antibody levels under high temperature(P＞0.05). |
