摘要
以蛋白质保护技术与ＮＰＮ级释技术相结合对能量饲料、蛋白质饲料和尿素等进行处理，以处理所得的复合蛋白质饲料替代精料中１００％的豆饼（试验１）和５０％的豆饼（试验Ⅱ组）饲喂奶牛。结果表明，精料成本分别降低了６．０７％和３．０８％；试验Ⅰ组日产奶量比对照组提高了１．２７千克（Ｐ＜０．０５），试验２组产奶量未得到显著提高（Ｐ＞ ０．０５）；试验组经济效益分别比对照组提高９．５１％和４．３７％。
Compound Protein foodstuff were utilized to substitute 100%(experiment I) and 50%(experiment II) soybean cake in concentrate of dairy cattle. The results showed that concentrate cost reduced by 6. 07% and 3. 089 respectively, as compared with that of the control; while the average daily milk production of the experiment I was 1. 27kg higher than that of the control(P<0. 05 ); the economic efficiency of experiment groups were 9. 51% and 4. 73% higher than that of the control group.
