摘　　要：TMR日粮的加工调制是提高生产效率的重要环节,本试验目的就是研究开发TMR日粮的加工调制技术规范。试验结果表明,粗饲料加工到3～4cm的长度,瘤胃pH值能够保持6.3以上的正常水平;产奶量达到153kg(<0.01);奶牛消化代谢紊乱现象解除,食欲大增,饲料进食量达到133.1kg;料奶比0.87:1。全面考虑上述试验结果和吉林省西部饲料资源的特点,笔者推荐在生产中使用粗饲料加工到3～5cm的长度,并且在精饲料比例提高时,应适当提高粗饲料加工的长度。TMR diet processing modulation is an important part of improving production efficiency,the purpose of this experiment is to study the development of processing and modulation of TMR diet specifications.The results showed that fodder processing to 3～4cm in length,rumen pH value of 6.3 or above to maintain the normal level;milk production to 153kg（P 0.01）;cow digestion and metabolism disorders phenomenon lifted,increased appetite,feed intake to 133.1kg;material milk than 0.87：1.Full account of the western province of the trial results and the characteristics of feed resources,Writer recommend the use of roughage in the production process to 3～5cm in length,and increase the proportion of concentrated feed,the process should increase the length of roughage.
