摘  要:
麦秸 ,大麦秸 ,黑麦秸和稻草经 2 .5%尿素 +5.0 % Ca(OH) 2 复合化学处理并压粒后 ,中性洗涤纤维 (NDF)下降到 67%~ 75% ,平均下降 6.5个百分点 ;粗蛋白从 3.5%~5.6%提高到 9.5%~ 1 1 .4% ,平均提高了一倍多 ;体外有机物消化率从 38%~ 45%提高到 57%~ 65% ,平均提高了 1 7.5个百分点 ,接近或超过了东北羊草和玉米青贮的水平。复合化学处理还提高了秸秆在瘤胃的降解率和降解速度。

摘  要:
Improving Effects of Different Compound Chemical Treatments on the Nutritional Value of Crop Straw were studied. The results showed that the content of neutral detergent fiber (NDF) in wheat, oat and rye straw treated with 2.5% urea and 5.0% Ca (OH) 2 and/or pelleting was reduced from 71~81% to 67~75%. The content of crude protein in these treated crop straw was raised from 3.5~ 5.6% to 9.5~11.4% and the in vitro digestibility of organic matter was raised from 38~45% to 57~65%, which is raised by 17.5% and up to or higher than that of northeast sheep fescues and corn straw silage. By these compound treatments, rumen degradability and degrading rate of crop straw were also improved.
