【摘要】 [目的]为了研究日粮中添加啤酒花渣对肉仔鸡生长性能的影响。[方法]采用单因子设计试验,选用300只1日龄AA肉鸡,随机分为6组,每组设5个重复。各试验组在饲粮中分别加入0、4%、8%、12%、16%、20%啤酒花渣,测定了体重、日增重、日均采食量等指标。[结果]添加啤酒花渣的试验组,1～42d整个试验期的体重、日增重和日均采食量均低于对照组。添加4%试验组饲料转化率在所有试验组中最高。利润随啤酒花渣添加量的增加而下降。[结论]综合考虑在肉仔鸡饲粮中添加4%啤酒花渣是可行的。该研究为啤酒花渣作为动物饲料提供了依据。更多还原

【Abstract】 Objective The research aimed to study the effects of supplementing hop residues to the diets on growth performance of broilers.Method Using single-factor design,300 AA broilers,1-day-old,were randomly divided into 6 groups with 5 repetitions.Supplementing 0 %,4 %,8 %,12 %,16 % and 20 % hop residues to the diets in tested groups,some indexes such as body weight,average daily weight and average daily feed intake were determined.ResultThe body weight,average daily weight and average daily feed intake in tested groups supplementing hop residues were lower than that in the control group in the whole tested period of 1~42 d.The feed conversion rate of tested group supplementing 4 % hop residues was the highest in all tested groups.Profits decreased with the increment of supplementing amount of hop residues.ConclusionConsidering synthetically,it was feasible for broilers to supplement 4 % hop residues to the diets.The study provided a basis for using hop residues as animal feed.更多还原
