摘要: 试验选用1~3胎次泌乳荷斯坦牛32头,按照产奶水平、泌乳阶段、胎次相近的原则,随机分为对照组、试验1、2、3组。对照组饲喂基础日粮,试验1、2、3组分别在基础日粮中添加0、12.5、125、250 mg/kg的葛根提取物。结果表明,与对照组相比,试验1、2、3组平均日产奶量分别提高了17.47%、9.68%、11.36%;且乳脂率和乳密度有所上升,乳中蛋白质、非脂固体等指标变化不大;试验组能提高奶牛血液中E2、COR、PRL含量,但无显著性差异(P>0.05)。因此,补饲葛根提取物可以缓解奶牛产奶量的下降。

Abstract: A total of 32 Holstein dairy cows at the same parity and with close lactation stage and similar daily milk yield were randomly divided into four groups: control group,group 1,group 2,group 3.The supplementary level of extracts of puerariae radix content of control group,group 1,group 2,group 3 were 0,12.5,25,250 mg/kg respectively,the basic diet was the same.The results showed that the milk yield of experiment group were more stable than that of control group(P>0.05);the milk yield of group 1,group 2,group 3 were more than that of control group for 17.47%,9.68%,11.36%.The milk fat proportion of experiment group were raised(P>0.05),but the milk proportion of protein,SNF and density were not changed;the plasma levels of E2,COR and PRL were raised(P>0.05).Therefore,supplement extracts of puerariae radix could lessen the decline tendency of milk yield.
