Effects of Glycerol Monolaurate on Growth,Health and Nutritional Quality of Chinese Soft-Shelled Turtle (Pelodiscus sinensis)
摘要
Abstract
This experiment was conducted to study the effects of glycerol monolaurate (GML) on growth, health and nutritional quality of Chinese soft-shelled turtle (Pelodiscus sinensis). In this study, a total of 24 000 Chinese soft-shelled turtle juveniles with an initial body weight of (50.23±14.92) g were divided into 2 groups with 20 replicates (tanks) per group and 600 turtles per tank. The turtles in control group were fed a basal diet, while those in experimental group were the basal diet supplemented 0.02％ GML for 200 days under the production conditions. The results showed that the weight gain rate, specific growth rate, carapace length, carapace width, and survival rate of turtles in the experimental group were significantly higher than those in the control group (P<0.05). Compared with the control group, the content of urea nitrogen and the activities of alkaline phosphatase, superoxide dismutase and lysozyme in serum in the experimental group were significantly increased (P<0.05), at the same time, the contents of crude protein, total flavor amino acids, total essential amino acids, total amino acids in meat and calipash and polyunsaturated fatty acids in meat were significantly increased (P<0.05). In conclusion, diets supplemented with 0.02％ GML can significantly improve the growth, health status and nutritional quality of Chinese soft-shelled turtle.关键词
