| Abstract: | The 20 yaks were divided into experimental and control groups,according to foetus rate,galactosis time,milk yield and weight.Yaks of experimental group fed with probiotics BLCS 5g/d;The control group were not fed.The results showed that the number of E.coli in the intestine of yak decreased significantly after feeding probiotics BLCS of(P<0.10);Lactobacillus was no significant difference between the groups(P>0.05),but higher than the experimental group.CP and DM digestibility of yaks fed with BLCS on the di... |
