| 摘 要： | 为研究调控饲料对奶牛产奶量和乳成分的影响,试验选择10头年龄、胎次、泌乳天数、产奶量相近的泌乳牛,按照配对试验设计分为2组,一组为对照组(饲喂基础日粮),另一组为试验组(饲喂添加调控饲料的基础日粮)。结果表明,试验组每头奶牛日均增奶量比对照组多1.366kg(P<0.05),乳蛋白、乳脂率、乳糖、乳中干物质含量相比差异不显著。通过试验前后对比可知,调控饲料显著提高了奶牛的产奶量。

| Abstract: | To study the effects of regulated feed on milk production and milk composition of dairy cows,10 dairy cows with the same age,fetal times,milking days and milk production were selected and divided into two groups in accordance with the paired experimental design.The dairy cows in control group were fed with the basal diet and that in test group was fed with the basal diet added with the regulated feed.The results showed that the daily milk yield of each dairy cow in test group increased 1.366 kg than that in control group(P<0.05) and the contents of milk protein,milk fat,lactose,dry matter in dairy cows in test group had no significant difference with that in control group.Through the contrast before and after the test,it was seen that regulated feed significantly improved milk production of dairy cows. |
