| 摘 要： | 实验１用４只安装永久性瘤胃漏管的阿尔巴斯白绒山羊（母），进行瘤胃消化代谢试验；实验２用６只成年母绒山羊进行消化代谢试验；试验３选用同品种成年妊娠母羊进行放牧补饲实验。实验１得出，稀土的使用可促进瘤胃内ＮＨ３－Ｎ的利用；细菌数比对照组提高３５．６７％；丙酸产量提高２８．６３％。实验２得出，稀土可提高绒山羊日粮ＤＭ、ＯＭ、ＧＥ及ＡＤＦ消化率，分别为１１．５８％、１２．２７％、１６．６９％和２６．２９％；每日氮存留率比对照组提高１８０．１％。实验３得出，稀土组产绒量比对照组提高８．９０％。

| Abstract: | In experiment I four Aerbasi white cashmere does fitted with permanent rumenfistulas were used and divided into two groups for studing rumen fermentation,Sixdoes were assigned to two groups to study digestion and metabolism in experiment 2.Inexperiment 3,20 grazing pregnant does were used and divided into two groups forstuding production performance.Experiment 1 shows that rare earth can increase the utilization rate of rumen NH3-N,and the bacterial population and propionic acid yield increase 35.67%and 28.63%,respectively.Experiment 2 shows that rare earth raises digestibility of DM,OM,GEand ADF by 11.58%,12.27%,16.69%,and 26.29%respectively,and daily body Nretaition was raised 180.1%,Rare earth can increase cashmere yild 8.90%inexperiment 3. |
