【摘要】：为分析比较奶牛常用饲料原料营养价值,本试验主要选择吉林、黑龙江、新疆区域主要饲料原料厂家产品,以玉米和豆粕为标尺,结合CPM奶牛配方软件,建立了泌乳价值与ME和MP的模型,通过概略养分分析,建立了营养价值与营养成分之间的模型,并对采购的饲料原料实际营养价值做出评估,并对饲料实际生产中采购某一种原料提供理论依据,结果表明:2014年,“泌乳价值”=560*ME+710*MP,营养价值=CP*65.19+NDF*6.76+EE*49.64+NFC*19.76R2=0.9998,2015年,营养价值=CP*35.27+NDF*11.04+EE*55.33+NFC*23.19R2=0.9993。综上所述,饲料原料营养成分与营养价值存在正相关,通过CPM软件泌乳价值模型和营养价值模型两种方法都可以有效的评价奶牛常用饲料原料的性价比。
[Abstract]:In order to analyze and compare the nutritional value of common feed raw materials for dairy cows, the main products of Jilin, Heilongjiang and Xinjiang regions were selected. The products were made from corn and soybean meal, combined with CPM milk formula software.The model of lactation value and ME and MP was established, and the model between nutritional value and nutrient composition was established by means of brief nutrient analysis, and the actual nutritional value of feed raw material was evaluated.The theoretical basis for purchasing a certain raw material in actual feed production was provided. The results showed that in 2014, the value of lactation was 560Me 710m, the nutritional value was 65.19 NDF*6.76 EE*49.64 NFC 19.76R20.9998, and in 2015, the nutritional value was 35.27 NDF*11.04 EE*55.33 NFC23.19R20.9993.To sum up, there is a positive correlation between the nutritional composition and nutritional value of feed raw materials. The value model of lactation and nutritional value model of CPM software can effectively evaluate the performance-price ratio of commonly used feedstuff in dairy cattle.
