| 摘 要： | 试验旨在研究不同能量蛋白水平对辽宁绒山羊产绒性能和营养物质代谢率的影响。试验采用随机区组设计,选取20只1周岁辽宁绒山羊,根据体重分为5组,每组4只。采用3个蛋白水平(7.7%、9.4%和11.2%)和3个代谢能水平(7.6、8.6、9.6 MJ/kg DM),设计5种日粮饲喂绒山羊。结果表明:不同能量水平对辽宁绒山羊绒细度有显著影响(P<0.05),对绒毛长度和绒毛强度没有显著影响(P>0.05);而不同蛋白水平对绒品质没有显著影响(P>0.05);能量和蛋白代谢率随日粮能量水平增加而增加(P<0.05);蛋白代谢率随日粮中蛋白水平增加而增加(P<0.05),辽宁绒山羊日粮中适宜的能量和蛋白水平分别为8.6 MJ/kg DM和9.4%。

| Abstract: | This research was conducted to study the effect of different energy and protein levels in diet on cashmere performance and associated indicators in Liaoning cashmere goat.A randomized experiment design was used.Twenty(1-year-old) Liaoning cashmere goats were divided by weight into five groups,and each group had four Liaoning cashmeregoats.The five groups of cashmere goats were fed with three levels of protein(7.7%,9.4% and 11.2%) and three levels of energy(7.6,8.6 and 9.6 MJ/kgDM).The results showed that di... |
