| 摘 要： | 实验研究了不同精粗比全混合日粮对奶牛生产性能和养分表观消化率的影响。实验选用了30头奶牛,根据产奶量、泌乳天数和胎次相近的原则分为5组。试验结果表明,随着全混合日粮中精料比例的增加,奶牛产奶量、4%标准乳产奶量、乳蛋白率、乳糖量、乳固形物产量和乳非脂固形物产量可显著提高(P<0.05),日粮养分中除粗脂肪外,其余各养分的表观消化率均随着日粮精料比例的增加而增加(P<0.05)。

| Abstract: | An experiment was designed to study the effect of forage to concentrate ratio on milk performance and apparent digestibility of nutrients in dairy cows fed total mixed ration. 30 cows were divided into five experiment group according to milk yield, calving date and lactation Period. The results indicated that the milk yields, 4% FCM yields, milk protein content, milk lactose yields, milk solid yields and milk solids-not-fat yields significantly increased(p<0.05) as concentrate increased in total mixed ration, and except the EE, the apparent digestibility of other nutrients respectively raised along with concentrate increased in total mixed ration (p<0.05). |
