Livestock and Poultry Industry(2020)
Abstract
为了探索核桃树叶饲养动物效果,选择2组349日龄的蛋鸡240只,分为试验组和对照组,每组120只,经过60 d的饲养试验,得出试验结果,试验组平均产蛋率88.13%;对照组平均产蛋率78.13%.试验组比对照组产蛋率多出10个百分点,提高12.8%(P<0.01);沙皮蛋率试验组0.06%,对照组0.29%,(P<0.01);发病死亡数试验组无鸡只死亡,而对照组发病死亡率为0.05%.对试验鸡蛋做胆固醇检测,试验组胆固285 mg/100 g,对照组338 mg/100 g,试验组比对照组鸡蛋内胆固醇减少15.68%.取得了核桃树叶养鸡的初步试验结果.
