| 摘 要： | 试验用６０周龄的豫州褐９１３蛋鸡３００只，随机分为３组，对照组（１）饮自来水，处理组（２，３）分别饮用含０．２６％，０．３４％的氯化钾（ＫＣｌ）水，在高温环境中试验４周，对热应激蛋鸡的某些生理指标和生产性能进行了研究。结果表明：ＫＣｌ可降低热应激蛋鸡的冠温、呼吸率和体温，尤其对呼吸率影响显著；同时ＫＣｌ能提高热应激蛋鸡的产蛋率，２组显著高于１组；ＫＣｌ对蛋重和饲料利用率影响不显著，但有使其升高的趋势。

| Abstract: | yuzhouhe laying hens at 60-week-old were randomly divided into three groups.Group l was control,drinking water was tap water.Group 2 and 3 were experimental groups,their concentrations of supplemental potassium chloride (KCl) in drinking water were 0.26% and 0.34% respectively.The experimental period prolonged four weeks in high environmental temperature.Some physiological parameters and laying performance of laying hens during heat strees were studied.The results showed that KCl dropped comb temperature.respiratory and body temperature of laying hens under heat stress,especially high significently dropped respiratory(P<0.01),while it improved the laying rate,and group 2 was significently improved(P<0.05).KCl did not significently affect egg size and feed efficiency but increased them. |
