A Study On The Utilization And Effects Of Total Mixed Ration (TMR) In Intesive Farms And Zones Of Dairy Cattle

This article studies the effect of total mixed ration technology in the large-scale farming distrct of dairy cattle at milking performance, SCC, economic effect , the feasibility analysis and process analysis of the popularity and applications of the technology in the large-scale farming distrct of dairy cattle, and further discuss the technical points, attention and recommendations of the popularity and applications of the technology in the distrct of dairy cattle, do some useful work for accelerating the popularization and application of TMR technology in the distrct of dairy cattle.The experiment of this study has been finished from 5th May,2007 to 15th August,2007 at the practice dairy farm of dezhou college (distrct model),the experiment was conducted to study the effect of total mixed ration(TMR) on milk performance, SCC and economic effect in dairy cattle at a breeding district. Sixteen healthy China Holstein cows divided into experiment group and control group according to milk yield,calving date, lactation and body weight, Ration level of two group was basic equal. The results indicated that: the average milk yield of experiment group increased by 1.49Kg compared with the control group, the 4% fat corrected milk(FCM) in the experiment group significantly increased by 2.85Kg compared with the control group (P<0.05 ); the milk fat content,milk protein rate,lactose and milk solid yields in the experiment group separate increased by 10.72%,0.34%,1.94 % and 1.09% than the control group; SCC of the experiment group reduced by 28.75% (P<0.01) than the control group; The economic effect analyses indicated that: the each in every day who the experiment group increased byï¿¥3.52 of net profit compared with the control group. The popularity and applications of the TMR technology in the distrct of dairy cattle is very necessary and feasible. In the popularity and application process, it is necessary to use the modern theory, pay attention to every technical aspect, using a variety of possible mode of operation to accelerate the speed of using advanced technology to transform traditional feeding cows, in order to achieve maximum efficiency.China is one of the countries of more cows in the amount in the word,dairy cattle breeding number to feed in the large-scale fanning distrct of dairy cattle, there is a substantial proportion in the total number of domestic cows, the most of dairy catties in the large-scale farming distrct use the traditional feeding system,the concentrate and the roughage were separated feeding. In such circumstances,discuss the popularity and applications of the TMR technology in the distrct of dairy cattle has important theoretical and practical significance.
