|
Six isonitrogenous and isoenergetic diets containing 0, 10, 25, 50, 65 and 77.5% fermented soyabean meal as substitutes for 0, 13.1, 32.7, 64.7, 83.6, and 100% of white fish meal were fed to juvenile soft-shelled turtles (Trionyx sinensis) for 8 weeks. Growth performance of turtles fed the diet containing 10% fermented soyabean meal (13.1% substitution of fish meal) was not different from those fed the control diet (0% fermented soyabean meal). Growth performance of turtles fed both control and 10% fermented soyabean meal diets was, however, better (P<0.05) than those fed higher dietary levels (25% or higher) of fermented soyabean meal. Feed conversion ratio and protein efficiency ratio of turtles fed control and 10% fermented soyabean meal diets were better (P<0.05) than turtles fed other diets. Body moisture content seemed to be inversely related to fermented soyabean meal content. Though CP and crude lipid of the body did not differ between groups, lowest values were noted in turtles fed diets containing high fermented soyabean meal (65 and 77.5%). The results show that 10% fermented soyabean meal could be used to replace 13.1% of fish meal in the diet of juvenile soft-shelled turtles.
