摘要:
本文主要研究饵料中B族维生素Vit.B1和Vit.B6对对虾肝胰脏淀粉水解酶和类胰蛋白水解酶活性的影响,从而阐述Vit.B1和vit.B6在对虾体内碳水化合物代谢和蛋白质代谢中所起的重要作用。实验结果表明,添加Vit.B1 6mg、Vit.B6 6mg╱100g饵组对虾肝胰脏淀粉酶比活性最高,是对照组的1.7倍,是组Ⅲ的3.8倍。类胰蛋白水解酶的比活性随饵料中Vit.B

THE EFFECTS OF VITAMIN B1 AND VITAMIN B6 ON THE DIGESTIVE ENZYME ACTIVITIES OF PENAEUS ORIENTALIS
Abstract:
The prawns were fed with the diets containing different contents of Vit. B1 and Vit. B6. The specific activities of α-amylase and tryptase of the prawn hepatopanceas were determined after 14 days. The results indicate that the digestive enzyme activities of the prawns were affected obviously by the contents of Vit. B1 and Vit. B6 in the diets. The specific activity of α-amylase was the highest, 1.7 times as control groups, when supplied 6mg Vit. B1 and 6mg Vit. B6/100g dry diets. The specific activity of the tryptase increased with the increase of concentration of Vit. B1 and B6 in the diets.
