摘要
为了探索不同尿素水平对氨化秸秆品质的影响,试验采用尼龙袋法测定尿素浓度分别为2.0%、4.5%、7.0%DM 的氨化秸秆及未氨化秸秆在山羊瘤胃48 h 的养分消失率。试验结果表明,氨化稻草秸秆在瘤胃48 h的干物质(DM)、中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)的降解率比未氨化稻草均有不同程度的增加,尤以尿素浓度为4.5%DM 的降解率为最高(p<0.05)。
To research the effect of the urea levels on ammoniated straw, the experiment adopted the nylon bags method to determine the dignstibility of nutrient of ammoniateed and non-ammoniated straw in the rumen of goats in 48h.The level of urea are 2.0%, 4.5%, 7.0%DM.The results showed that the degradability of dry matter（DM）, neutral detergent fiber（NDF）, and acid detergent fiber（ADF） of ammoniated straw in rumen in 48h was higher than that of untreated straw, especially the degradability at the level of 4.5% was the highest, having significant difference（p〈0.05）.
