【摘要】：為分析比較奶牛常用飼料原料營養(yǎng)價值,本試驗主要選擇吉林、黑龍江、新疆區(qū)域主要飼料原料廠家產(chǎn)品,以玉米和豆粕為標尺,結合CPM奶牛配方軟件,建立了泌乳價值與ME和MP的模型,通過概略養(yǎng)分分析,建立了營養(yǎng)價值與營養(yǎng)成分之間的模型,并對采購的飼料原料實際營養(yǎng)價值做出評估,并對飼料實際生產(chǎn)中采購某一種原料提供理論依據(jù),結果表明:2014年,“泌乳價值”=560*ME+710*MP,營養(yǎng)價值=CP*65.19+NDF*6.76+EE*49.64+NFC*19.76R2=0.9998,2015年,營養(yǎng)價值=CP*35.27+NDF*11.04+EE*55.33+NFC*23.19R2=0.9993。綜上所述,飼料原料營養(yǎng)成分與營養(yǎng)價值存在正相關,通過CPM軟件泌乳價值模型和營養(yǎng)價值模型兩種方法都可以有效的評價奶牛常用飼料原料的性價比。
[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.
