不同饲粮肥育淘汰绵羊的效果

Effects of Different Ration on Fatting Culling Sheep

用淘汰育成绵羊和成年绵羊同时进行两个试验，分别研究用缓释尿素替代部分饲料蛋白质和以不同饲养水平肥育绵羊的效果。试验１的结果表明，可以用缓释尿素替代部分植物性蛋白质饲料肥育育成绵羊；试验２结果说明，用低营养和较高营养水平日粮肥育成年绵羊的效果差别不大。

Two experiments were conducted by using culling hogg and adult sheep to investigate the effects of feed with some slow-releasing urea replacing some feed protein and different nutritional levels on fatting sheep.The results of these two expriments were as follows:1.It was practicable to use the slow-releasing urea replacing some feed protein to fat culling hogg;2.The effect of fatting adult sheep using lower and higher nutritional ration was no difference.
