氢氧化钠+尿素同步处理稻草喂牛试验研究

用1％氢氧化钠+3％尿素复合同步处理稻草,粗蛋白质含量增加4％。用其喂产奶牛,粗纤维消化率提高31.6％,干物质消化率提高12.5％,采食量提高48％,日产奶量比对照组提高20.7％,幼牛日增量提高100％,实践证明,这种复合同步处理兼顾了碱与尿素处理的各自优点,是目前化学处理秸秆饲料的一种新的科学方法。

Study on a Test of Feeding Caw with Syrchronism Treated Straw by NaOH and Urea

Syrchronism treated straw with 1%NaoH and 3% urea, crude protein Content of straw increases by 4%,when feeding cow with the treated straw,the digestibility for crude fiber goes up by 31.6%, that of dry matter by 12.5%,feed intake by 48%, while daily milk yield is 20. 7% higher than control group, average daily gain calf is doubled, practice has proved that this treatment of straw covers the potency of both NroH-treatment and urea -treatment, and is at present a new scientiific method chemical treatment of straw.
