摘要
选择1 000只生产性能正常的本地黑鸡(蛋鸡),随机分为试验组与对照组。试验组采用发酵床垫料,结果显示:试验组的产蛋率、蛋料比、蛋的平均重量、蛋的均匀度、疫病防控等指标均好于对照组;试验组鸡舍NH3的浓度低于对照组,粪便降解充分;试验组垫料由上至下形成温度梯度,但试验组与对照组垫料表面温度差异不显著;试验组平均每天比对照组多增加经济效益22.26元。说明建立的试验方法可行。
1,000 local black chickens （Egg layer） were assigned to experimental to experimental group and control randomly. Control group was raised by conventional method and experimental group by Mattress fermented feed method. The results showed that the indexes in test group including egg production rate, ratio of egg, average weight of egg, uniformity of egg, disease prevention and control were materials formed temperature gradient in test group from top to bottom, whereas there was no significant difference of surface tempera-been used in this was practical.
