Effect of Low-Gossypol Cottonseed Meal,the Substitute of Soybean Meal,on Growth,Feed Utilization and Immune Response of White Shrimp(Litopenaeus vannamei)
摘要
Abstract
To determine the effect of low-gossypol cottonseed meal,the substitute of soybean meal,in the feed of Litopenaeus vannamei,a six-week culture experiment was conducted using L.vannamei with an initial body weight of(0.81±0.01)g.The diets containing 25%,50%,75%and 100%of soybean meal(documented as S25,S50,S75,S100),correspondingly 4.93%,10.06%,14.80%and 19.73%of low-gossypol cottonseed meal and equal protein,respectively,were prepared and used to feed shrimps,70 individuals each treatment,3 replicates.The control group was fed the diet containing 25%of soybean meal.The results showed that the substitution of 100%soybean meal with low-gossypol cottonseed meal does not significantly affect the growth and feed utilization of shrimp,but the trypsin and amylase activities,the apparent dry matter and crude protein digestibility are significantly decreased.The expression of immune-related genes in the intestine of shrimp was significantly higher when 75%soybean meal was replaced by low-gossypol cottonseed meal than that of control.Intestinal histomorphological observation found that the replacement of soybean meal by low-gossypol cottonseed meal affects the intestinal health of shrimp.The intestinal villus height was significantly reduced when the substitution rate reached 100%.Our findings indicated that the substitution of 100%soybean meal in the diet with low-gossypol cottonseed meal does not significantly affect the growth and feed utilization of shrimp,but affects the digestion,immune response and intestinal health of shrimp.关键词
