摘要
在膨化玉米与鱼肉为主的水貂日粮中加入淀粉酶与中性蛋白酶,通过水貂的糖代谢指标来衡量日粮中添加外源酶对水貂的糖代谢是否产生影响。试验应用56只16周龄健康短毛黑水貂,采用2×3复因子试验设计,研究添加外源淀粉酶与蛋白酶对水貂糖代谢水平。结果表明:水貂的育成期,在传统的日粮条件下,添加淀粉酶与蛋白酶,对各试验组水貂肝糖元含量并无显著影响;对水貂公貂间血糖水平影响不显著;对母貂间血糖水平影响显著(P<0.05);添加高水平淀粉酶组效果最明显。本试验淀粉酶的添加提高了水貂体内的糖代谢水平,但并未改变水貂体内的糖储备。
Effect of extraneous enzyme to sugar metabolism in mink. 56 16-week-old minks were allocated randomly into 7 groups, The trail adopted 2 ×3 multiple factor experimental design. Effect of additive amylase and papain to sugar metabolism in mink was investigated. The result indicates that effect of additive amylase and papain to glycogenic content of mink is not significant （P〉 0.05） when feed is a traditional diet in young mink period, Effect of additive amylase and papain to content of blood sugar of male mink is not significant （P 〉 0.05）. Effect of additive amylase and papain to content of blood sugar of female mink is significant （P 〈 0.05）. Effect of high level additive amylase to content of blood sugar of mink is more significant, Content of blood sugar of mink in high level additive amylase group is higheby 46.83% than antitheses group.
