本试验旨在研究饲粮油脂和脂肪酶添加水平对热应激肉鸡生长性能和血清生化指标的影响。试验采用5×2双因子设计,选取21日龄、体重相近的健康爱拔益加(AA)肉鸡500只,随机分为10个组,每组5个重复,每个重复10只鸡(公母各占1/2)。各组肉鸡分别饲喂不同油脂水平(5.53%、6.71%、7.89%、9.07%、10.25%)和脂肪酶添加水平(0、6 000 U/kg)组合的10种试验饲粮。试验在环控鸡舍[温度为(33.98±1.44)℃ 、相对湿度为(66.26±5.42)%]中进行,试验期21 d。结果表明:1)Ⅳ组肉鸡的平均日采食量(ADFI)显著高于Ⅰ、Ⅱ、Ⅴ、Ⅶ、Ⅷ、Ⅸ组(P

The purpose of this experiment was to study the effects of dietary oil and lipase supplemented levels on growth performance and serum biochemical parameters of heat-stressed broilers.Five hundred healthy Arbor Acres(AA)broilers of 21-day-old and with similar body weight were randomly divided into 10 groups with 5 replicates per group and 10 broilers(males and females in half)per replicate by a 5 ×2 two factor design.Broilers among groups were fed 10 test diets with different oil levels(5.53%,6.71%,7.89%,9.07%,10.25%)and lipase supplemented lev...
