Abstract:

This study aims to investigate the effect of taurine on the growth performance, non-specific immunity and antioxidative competence of Procambarus clarkii. 300 juvenile red swamp crayfish Procambarus clarkii with initial body weight of (4.50±0.50) g were selected and randomly divided into five groups. The five groups were fed with five isonitrogenous and isoenergetic diets with different taurine contents respectively. After feeding for 4 weeks, we investigated the growth performance, biochemical parameters of blood and liver. In 200 and 300 mg/kg treatment groups, some indices were significantly higher than those of the control group (P<0.05), such as the weight gain, dressing percentage, the levels of total protein (TP), lysozyme (LSZ), and the activities of superoxide dismutase (SOD) and catalase (CAT) in liver. In 200 and 300 mg/kg treatment groups, serum glutamic-pyruvic transaminase (GPT) and glutamic-oxaloacetic transaminase (GOT) were lower than those of the control group (P <0.05), which had the statistical difference. In 300 mg/kg treatment group, the activities of GSH-Px and survival rates were significantly higher than those of the control group (P <0.05), feed coefficient was significantly lower than that of the control group (P<0.05). However, there was no statistical difference in the contents of malondialdehyde (MDA) among the five groups. Therefore, the diet supplemented with 200-300 mg/kg taurine could promote the growth of Procambarus clarkii, improve the non-specific immunity and antioxidative competence, and enhance its disease resistance.
