Establish Of Nutritional Value Evaluation System On The Basis Of Cows Feed Ingredients Commonly Used

Commonly used for the analysis and comparison cows feed ingredients, nutritional value, this experiment mainly choose to jilin, heilongjiang, xinjiang area mainly feed raw materials manufacturers, with corn and soybean meal as yardstick, combined with CPM cows formula software, established the lactation value with ME and MP model, through the general nutrient analysis, established a model between nutrients and nutritional value, and for the purchasing of feed raw material actual nutritional value assessment, and in the actual feed production provides the theory basis for purchasing a certain raw material.The results showed that: in 2014, "lactation value" = 560*ME+710*MP, Nutritional value R2=0.9998 =CP*65.19+NDF*6.76+EE*49.64+NFC*19.76, 2015, nutritional value R2=0.9993 =CP*35.27+NDF*11.04+EE*55.33+NFC*23.19In summary, feed raw materials, nutritional ingredients and nutritional value exist positive correlation, by two methods, CPM software lactation value model and the nutritional value of the model can be an effective evaluation in traditional dairy feed raw material price.
