摘要
The supplemental effect of dried yeast on growth, feed intake, feed conversion and apparent nutrient retention of broiler chicks fed a high-fibre diet was studied for 28 days. One hundred and fifty 7-day-old broiler chicks were fed five high-fibre diets containing 250 g kg−1 palm kernel meal. The diets were supplemented with increasing levels of dried yeast: 0, 1.5 g kg−1, 3.0 g kg−1, 4.5 g kg−1 and 6.0 g kg−1. The unsupplemented treatment was the control. Dried yeast supplementation improved body weight gain of chicks, with the highest average daily gain being achieved by chicks fed 3.0 g kg−1 of dried yeast. Feed intake was similar on all treatments, except for the exceptionally lower consumption by chicks fed 6.0 g kg−1 dried yeast. Feed conversion efficiency was highest in chicks fed 6.0 g kg−1 of dried yeast and lowest in those fed the control diet. The apparent retention coefficients were higher with dried yeast supplementation, except those of acid detergent fibre and acid detergent lignin.

研究干酵母对饲喂高纤维日粮的肉仔鸡的生长，采食量，饲料转化率和表观养分保留的补充效果，为期28天。105日龄肉仔鸡饲喂5种含250g / kg棕榈仁粕的高纤维日粮。日粮中添加了越来越多的干酵母：0，1.5 g kg -1，3.0 g kg -1，4.5 g kg -1和6.0 g kg -1 -1 。没有补充的治疗是对照。补充干酵母可以改善小鸡的体重增长，平均每日增重最高的是通过3.0 g / kg干酵母饲喂雏鸡。所有处理的饲料采食量相似，只是饲喂6.0克kg-1干酵母的小鸡的消费量非常低。雏鸡饲喂转化效率最高6。干酵母0g·kg-1，对照饮食的最低。干酵母添加量的表观保留系数较高，酸性洗涤剂纤维和酸性洗涤剂木质素除外。
