摘    要:设计中草药配方Ⅰ和Ⅱ,分别以0.5%、1%、2%剂量添加到基础饲料中,连续投喂异育银鲫2个月后,测定鱼体的相对增重率、肠道和肝胰脏的蛋白酶活性及消化吸收率。结果表明,中草药添加剂能够极显著地影响异育银鲫的生长、肠道和肝胰脏的蛋白酶活性及蛋白质的消化吸收率(P<0.01)。配方Ⅰ以1%组和2%组、配方Ⅱ以2%组的生长最佳,相对增重率分别比对照组提高23.47%、32.74%和47.06%。中草药添加剂对肠道、肝胰脏蛋白酶活性及消化吸收率的影响与生长相似,对照组肠道蛋白酶活性为10.54,配方Ⅰ中1%组为20.33、2%组为22.79,配方Ⅱ中2%组为25.68;肝胰脏蛋白酶活性,对照组为8.54,配方Ⅰ中1%组为14.13、2%配方Ⅰ组为16.59,2%配方Ⅱ组为20.36。对照组的蛋白质消化吸收率为78.15%,1%配方Ⅰ组为84.38%,2%配方Ⅰ组为86.98%,2%配方Ⅱ组为88.19%。因此中草药添加剂提高蛋白酶活力、促进蛋白质的消化吸收,是促进鱼体生长的重要因素。

Abstract:Allogynogenetic crucian carp( body weight 1. 6- 2. 2g ) were fed with formulated diet which had been added w ith Chinese herb ( additive ., additive ò) at different contents of 0. 5% , 1% and 2% respectively. Growth rate, apparent digestibility of protein and protease activity in intestine and hepatopancreas were determined in two months. The results showed that Chinese herb additives signif icantly increased growth rate, protease activity in intestine and hepatopancreas, and apparent protein digestibility of allogynogenetic crucian carp( P < 0. 01) . The growth rates of the treated groups 1% of additive ., 2% addit ive . and 2% additive ò were 23. 74% , 32. 74% and 47. 06% higher than those of the control respectively. The effect of the additives on protease activity in intestine and hepatopancreas, and apparent digestibility of protein was the same as the growth rate. Protease act ivities of the control and the treated groups 1% of additive ., 2% addit ive . , 2% additive ò in intestine were 10. 54, 20. 33, 22. 79, 25. 68, and those in hepatopancreas were 8. 54, 14. 13, 16. 59, 20. 36 respectively. Apparent protein digestibities of these groups were 78. 15%, 84. 38%, 86. 98% and 88. 19%. Therefore the increase of the protease activites and absorbabilities was an important factor to increase fish gro
