摘要
为探讨微贮甜玉米秸秆饲料对奶牛生产性能的影响,以南方高水分甜玉米秸秆为原料,分别采用微贮与传统青贮方法处理后组成日粮饲喂奶牛。结果表明,微贮甜玉米秸秆饲料品质优于传统青贮处理,具有更高的营养价值和适口性。在饲养管理和基础日粮相同的前提下,饲喂微贮甜玉米秸秆饲料可显著提高奶量(3.79%),每头日均增产牛奶0.76kg,每头日均多收益2.04元,每头年均多收益622.20元。因此,大力推广微贮甜玉米秸秆,对大规模奶牛场具有非常可观的经济效益。
The effects of microbial silage sweet maize straw feed on the productivity of dairy have been investigated. The south sweet maize with high-water was treated with microbial silage and conventional silage methods and fed to animals as daily feed. The results showed that the quality of microbial silage maize straw feed was better than that of conventional silage treatment, and it had higher nutritional value and palatability. Under same condition of feeding management and basic daily diet, feeding microbial silage maize straw feed could significantly increase the yield of milk （3.79%） as compared to conventional silage. The daily yield of milk of a dairy cow increased by 0.76 kg with 2.04 Yuan RMB in benefit, as well 622.20 Yuan RMB of annual increase in benefit. Therefore, the use of microbial silage maize straw as a cattle feed can increase the economic benefit considerably.
