饲粮中添加啤酒花渣对肉仔鸡营养物质代谢的影响

试验选用300只1日龄AA肉仔鸡,随机分为6组,每个组设5个重复.各试验组在饲粮中分别加入0、4%、8%、12%、16%、20%的啤酒花渣.结果表明,添加8%、12%、16%和20%的啤酒花渣试验处理,使肉仔鸡的能量表现存留率、干物质表观存留率、有机物表观存留率均随着添加量的增加而降低(P＜0.05或P＜0.01);而4%的处理无显著差异(P＞0.05).20%的处理显著降低了粗蛋白表观存留率(P＜0.01)、钙表观存留率(P＜0.01)和磷表现存留率(P＜0.05);16%的处理显著降低了粗蛋白袁观存留率(P＜0.05);8%的处理和12%的处理显著降低了钙表现存留率(P＜0.05或P＜0.01).随着饲粮中啤酒花渣添加量的增加,营养物质的存留率有降低的趋势,但在饲粮中添加4%的啤酒花渣对内仔鸡的营养物质代谢没有显著影响.

Effect of Hop Residue Supplementation on Nutrient Metabolizing of Broilers

The experiment was conducted to study the effects of hop residues on the growth performance of the broilers.A total of 300 AA male broilers were divided into six groups(containing hop residue 0,4%,8%,12%,16%,and 20%).Each group contained five replicates with 10 broilers.The trial lasted 42 days.The result showed that: 8%,12%,16% and 20% hop residue decreased the rate of energy deposition,dry matter deposition and organic matter deposition of the broilers in each group as the increasing of hop residue in the...
