摘要
试验用544只商品代罗斯蛋鸡,研究产蛋鸡饲粮中添加不同比例的水化菜油脚(rapeseedoil rasidue)对鸡群生产性能的影响。结果表明,添加不同比例(3％、6％、9％)的菜油脚对产蛋率、蛋重、蛋壳厚、蛋比重、蛋白品质和料蛋比均无显著影响。并且添加菜油脚后可降低饲粮成本,减少血斑蛋和肉斑蛋的产生,减少或防止母鸡的脂肪肝病,认为菜油脚的添加比例在9％范围内可行。
Results of feeding experiments with 544 layers showed that 3%, 6% and 9%of rapeseed oil residual in mixed feeds were no influnce upon the laying rate, weight of egg, shell thickness and specific gravity of egg but lower the feeding cost.
