摘要
在长颈鹿日粮中添加精料量的 0 0‰、 0 8‰、 1 0‰、 1 2‰剂量华芬酶 - 16 0 0 ,采用分期试验法对 3只成年健康长颈鹿进行 4期消化试验。结果表明 ,添加外源酶后 ,长颈鹿对日粮干物质、粗蛋白、粗脂肪、粗纤维的消化率均明显提高 (P <0 0 5 ) ,尤其是粗纤维的消化率 ,以第Ⅳ期 (添加 1 2‰ )最为显著 (P <0 0 5 )。因此 ,推荐添加量为 1 2‰。
Three same-age healthy Giraffa camelopardalis were selected for four digestible tests with the addition of an exotic compound, Huafen Enzymes-1600 in their diets. Results indicated that adding the exotic enzyme could significantly improve digestibility of dry matter, crude protein, crude fat, and cellulose(P<0.05), especially cellulose. As far as the forage digestibility, a reasonable addition of 1.2‰ of the Huafen Enzymes-1600 is recommended.
