【摘要】 应用“酶”分析法对几种粗饲料和不同精、粗饲料比的 3种日粮的化学成分进行了分析 ,并利用低消化性纤维 (Ob)含量不同的日粮进行了饲养和消化试验。结果表明 :细胞内容物有机物部分 (OCC)含量花生藤最高 ,稻杆含量最低 ;细胞壁物质有机物部分 (OCW)中的 Ob含量以稻杆最高 ,花生藤含量最低 ;日粮中精料比例每提高 10 % ,Ob含量减少约 2 .3% ;山羊的日增重以精、粗饲料比 2 :3,Ob含量37.75 %的效果最好 ,日粮中 Ob含量过多或过少 ,都将影响山羊的日增重 ;OCW中的高消化性纤维(Oa)的消化率为 6 3.38% ,Ob的消化率为 19.2 1%。更多还原

【Abstract】 By the enzyme analytic method, we analyzed the chemical composition of several kinds of roughage and 3 kinds of diet with different concentrate and roughage ration, and conducted the feeding trial and the digestion trial by using the diets with different content of low digestible cellulose(Ob).The results showed that the organic compound in cellular contents (OCC) content was the highest in peanut vine and lowest in rice straw;Ob content of organic compound in cell wall substances (OCW) was the highest in rice straw and the lowest in peanut vine;Ob content was decreased by about 2.3% when the concentrate in diet was increased by 10%;the concentrate and roughage ration as 2∶3 and 37.7% of Ob content would gain the most daily weight of goat,more or less than 37.75% Ob content would affect goats growth,the digestibility of high digestible cellulose (Oa) and of Ob OCW was 63.38% and 19.21% respectively.更多还原
