Effects of dietary glutamine dipeptide on growth performance, intestinal digestive enzyme activity, and gene expression of related factors in Penaeus vannamei

The effects of glutamine dipeptide (GDP) on the growth performance, intestinal digestive enzyme activity, immune metabolism index, and gene expression of related factors of Penaeus vannamei were investigated in present study. Results showed that GDP obviously increased the weight gain rate, specific...

Zusammenfassung:The effects of glutamine dipeptide (GDP) on the growth performance, intestinal digestive enzyme activity, immune metabolism index, and gene expression of related factors of Penaeus vannamei were investigated in present study. Results showed that GDP obviously increased the weight gain rate, specific growth rate, and survival rate of P. vannamei but decreased the feed conversion ratio (FCR). The activities of amylase, protease, catalase (CAT), glutathione peroxidase (GSH-Px), and Na + –K + –ATPase in the intestine of P. vannamei fed with 0.5% and 1% GDP were significantly higher than those of the control group ( P
