| 摘 要： | 为研究低蛋白补饲过瘤胃赖氨酸（RPLys）对山羊生长性能与血液生化指标的影响，试验将18只山羊随机分为3组，对照组、处理Ⅰ组、处理Ⅱ组，每组6个重复，每个重复1只羊。对照组饲喂基础饲粮，粗蛋白质（CP）水平为12%，不含RPLys|处理Ⅰ组CP为10%，补饲0.5%的RPLys|处理Ⅱ组CP为10%，补饲1%的RPLys。结果显示：（1）各组山羊的生长性能差异不显著（P > 0.05）|2个处理组的CP和粗脂肪（EE）消化率高于对照组（P < 0.05），且处理Ⅱ组高于处理Ⅰ组（P > 0.05）。（2）各组山羊的血液生化和抗氧化指标差异不显著（P > 0.05）。由此可知，在低蛋白时补饲RPLys可提高山羊饲粮养分消化率，未对血液生化指标和抗氧化能力产生不良影响。综合来看，RPLys的添加水平为1%时效果最好。

| Abstract: | This study was conducted to investigate the effects of rumen-protected lysine(RPLys)addition in low protein level diet on growth performance and plasma metabolites of Qianbei miscellaneous goats.Eighteen goats were randomly divided into 3 groups:control group,treatmentⅠgroup,treatmentⅡgroup with 6 replicates in each group and 1 goat in each replicate.Goats in the control was fed a basal diet(CP=12%)without RPLys;treatmentⅠgroup and treatmentⅡgroup were fed diets(CP=10%)supplemented with 0.5%and 1%RPLys,respectively.The results showed that:(1)The dry matter intake(DMI),average daily weight gain(ADG),and ratio of feed to gain(F/G)were not significantly different(P>0.05).The digestibility of crude protein and ether extract in treatmentⅠgroup and treatmentⅡgroup were higher than control group(P<0.05).The crude protein and ether extract digestibility in treatmentⅡgroup were higher than treatmentⅠgroup(P>0.05).(2)There was no difference in plasma metabolites among all groups(P>0.05).It was suggested that the addition of RPLys in low crude protein level diet have no adversely influences on growth performance and plasma metabolites for goats,and it could increase the utilization of crude protein and crude fat in the diet.Addition of 1%RPLys has the best performance. |
