| 摘 要： | 在奶牛日粮中每头添加50g·d-1CB酵母(Candida tropicalis Berkhout)。结果表明,CB可提高产奶量11.2%,试验组产奶量与对照组产奶量差异显著(P<0.05);乳蛋白含量提高5.13%,试验组与对照组乳蛋白差异显著(P<0.05);乳中乳脂率含量有所提高,但差异不显著(P>0.05);乳中干物质含量有增加趋势,但差异不显著。

| Abstract: | Add 50 grams CB yeast in earlier lactating cow food everyday, result enunciation: CB increased milk yield by 11.2%, testing group milk yield is significant difference (P <0.05) than control group; CB increased milk protein contains by 5.13%, testing group milk protein contains is significant difference (P <0.05) than control group. Milk fat contains has exaltation, but have insignificant difference (P >0.05); dry matter contains of milk is increment trend, but have insignificant difference (P >0.05). |
