过瘤胃蛋氨酸对滩羊羔羊生产性能及羊毛品质的影响

Effect of Rumen Protected Methionine on Production Performance and Wool Quality of Tan Lamb

采用饲养试验,研究过瘤胃蛋氨酸对滩羊羔羊生产性能及羊毛品质的影响。结果表明,试验组日粮添加4g/d过瘤胃蛋氨酸可显著提高滩羊羔羊平均日增重和干物采食量(P<0.05),且料重比比对照组降低1.44,每只羊的经济收益比对照组增加23.94元。试验组羊毛自然长度、伸直长度和净毛率显著提高(P<0.05),羊毛密度和羊毛细度与对照组无显著差异(P>0.05)。研究结果说明,日粮添加4g/d过瘤胃蛋氨酸对滩羊羔羊的生产性能和羊毛品质具有促进作用。

The effects of rumen protected methionine on productive performance and wool quality were studied in Tan lamb using feeding experiment.The results showed that adding rumen protected methionine 4 g/d in diet can significantly improve average daily weight gain and dry matter intake（P〈0.05）in Tan lamb,and the feed conversion ratio was lower than the control group by 1.44.The profitability of each sheep was higher than the control group by 23.94 yuan.The wool natural length and staple length and clean wool yield of test group all increased significantly in this experiment,while the density of wool and wool fineness have no significant difference compared to the control group（P〉0.05）.This experiment shows that adding the rumen protected methionine 4 g/d in the diet can promote production performance and wool quality of Tan Lamb.
