摘要
文章旨在研究发酵豆粕替代鱼粉对黑斑蛙生长性能、体形指数及血浆生化指标的影响。试验将800只同批孵化、健康、初重[(2.7±0.1)g]一致的黑斑蛙随机分到20个养殖试验池中,每5个试验池为一组,试验组分别使用0%、10%、20%、40%的发酵豆粕替代基础日粮中的鱼粉,试验为期60 d。结果表明,使用20%和40%的发酵豆粕替代基础日粮中的鱼粉显著降低黑斑蛙6.80%和7.49%的末体重(P<0.05);黑斑蛙的增重率分别显著降低7.84%和7.44%(P<0.05);黑斑蛙的特定生长率分别显著降低3.05%和2.89%(P<0.05);此外,发酵豆粕对黑斑蛙成活率、摄食率和饲料系数均无显著影响(P>0.05)。使用20%和40%的发酵豆粕替代基础日粮中的鱼粉可显著降低黑斑蛙的肥满度和肝体比(P<0.05);使用20%和40%的发酵豆粕替代基础日粮中的鱼粉可显著降低黑斑蛙的胴体比(P<0.05);此外,日粮添加发酵豆粕对黑斑蛙后腿指数和器官指数均无显著影响(P>0.05)。使用20%和40%的发酵豆粕替代基础日粮中的鱼粉可显著降低黑斑蛙血浆TG和HDL含量(P<0.05),显著提高黑斑蛙血浆TC含量(P<0.05);此外,使用发酵豆粕替代基础日粮中的鱼粉对黑斑蛙血浆LDL含量、AST和ALT活性均无显著影响(P>0.05)。结论:使用发酵豆粕替代鱼粉(20%和40%)对黑斑蛙生长性能有显著负面影响,在本试验条件下最适替代量为10%。
(Experimental objective)To explore the effects of fermented soybean meal replacing fish meal on the growth performance,body shape index,and plasma biochemical indicators of the black spotted frog.(Experimental design)800 healthy black spotted frogs with the same initial weight[(2.7±0.1)g]were incubated in the same batch and randomly divided into 20 breeding test pools.Each of the 5 test pools was used as a group.The experiment used 0%,10%,20%,and 40%fermented soybean meal instead of fish meal in the basic diet as the experimental feed.The breeding experiment lasted for 60 days.(Experimental results)Using 20%and 40%fermented soybean meal instead of fish meal in the basic diet significantly reduced the final body weight of black spotted frogs by 6.80%and 7.49%(P<0.05);The weight gain rate of the black spotted frog significantly decreased by 7.84%and 7.44%,respectively(P<0.05);The specific growth rates of the black spotted frog were significantly reduced by 3.05%and 2.89%,respectively(P<0.05);In addition,fermented soybean meal had no significant effect on the survival rate,feeding rate,and feed coefficient of the black spotted frog(P>0.05).The use of 20%and 40%fermented soybean meal instead of fish meal in the basic diet significantly reduced the fat content and liver to body ratio of the black spotted frog(P<0.05);The use of 20%and 40%fermented soybean meal instead of fish meal in the base diet significantly reduced the body ratio of the black spotted frog(P<0.05);In addition,adding fermented soybean meal to the diet had no significant effect on the hind leg index and organ index of the black spotted frog(P>0.05).The use of 20%and 40%fermented soybean meal instead of fish meal in the basic diet significantly reduced the plasma TG and HDL content of black spotted frog(P<0.05);The use of 20%and 40%fermented soybean meal instead of fish meal in the basic diet significantly increased the plasma TC content of the black spotted frog(P<0.05);In addition,the use of fermented soybean meal instead of fish meal in the basic diet had no significant effect on the plasma LDL content,AST and ALT activities of the black spotted frog(P>0.05).(Experimental conclusion)The use of fermented soybean meal instead of fish meal(20%and 40%)has a significant negative impact on the growth performance of the black spotted frog.Under the experimental conditions,the optimal substitution amount is 10%.
