刺五加浸膏对高温热应激时蛋种鸡生产性能及氮沉积的影响

Effects of eleutherococcus extract on productivity of breeding layers and N deposit at heat stress

研究了夏秋高温热应激期间，在蛋种鸡日粮中添加中药刺五加浸膏对产蛋性能、种蛋受精、孵化及小公鸡氮沉积的影响。结果表明，试验组（添加０１％刺五加组）产蛋率比对照组提高１０２％（Ｐ＜００１），料蛋比下降９２％（Ｐ＜００１），破软壳蛋减少１８５％（Ｐ＜００１），鸡死亡淘汰率下降１０３％（Ｐ＞００５），种蛋受精率提高１７５８％，种蛋孵化率提高１７７６％。氮平衡试验结果表明，剌五加浸膏对小公鸡氮沉积量有提高趋势，氮沉积率提高９１％。

The study was conducted to examine the effects of the diet added eleutherococcus extract (EE) on productivity, egg fertilization, egg hatch of breeding layers and N deposit of cockerel under hot ambient temperature The results showed that the laying rate, egg fertilization rate and hatch rate in EE group (01%) were respectively increased 102% (P<001), 1758% and 1776% Meanwhile, feed conversion ratio, soft and broken eggs, death rate in EE group were respectively reduced 92% (P<001), 185%(P<001) and 103% (P>005), comparing to the control In addition, EE could increase N deposit of cockerel about 91%, comparing to the control The results showed that EE is of good anti-heat stress effects on breeding layers
