Leg weaknesses occurring in commercial broiler chickens were studied in three experiments. No significant improvement was obtained by added dietary levels of known anti-perotic factors. Definite improvements in leg weaknesses occurred when the complete, practical diet was supplemented with 2.5 and 5.0% brewer's dried yeast.
在三个实验中对商品肉鸡出现的腿部软弱问题进行了研究。提高已知抗神经炎因子的日粮添加水平并未取得显著改善。当在完整的实用日粮中添加2.5%和5.0%的啤酒干酵母时,腿部软弱问题有了明显改善。
