| 摘 要： | 为探讨配合饲料中分别添加蛹肽粉和蝇蛆粉对拟穴青蟹幼蟹生长性能、体成分和消化酶活性的影响，在基础饲料中分别添加10%的蛹肽粉和蝇蛆粉，饲喂拟穴青蟹幼蟹45d。结果表明：蛹肽料组拟穴青蟹幼蟹增重率、特定生长率显著高于基础料组和蝇蛆料组(P<0.05)，蛹肽料组拟穴青蟹幼蟹成活率显著高于基础料组(P<0.05)；基础料组拟穴青蟹幼蟹水分含量显著低于蛹肽料组和蝇蛆料组(P<0.05)，粗蛋白含量则表现出相反的结果(P<0.05)，拟穴青蟹幼蟹粗脂肪含量为：基础料组＞蝇蛆料组＞蛹肽料组(P<0.05)；拟穴青蟹幼蟹蛋白酶活性为：基础料组<蝇蛆料组<蛹肽料组(P<0.05)，淀粉酶活性表现出与蛋白酶活性相同的结果(P<0.05)，脂肪酶活性则为蛹肽料组与蝇蛆料组显著高于基础料组(P<0.05)。综上所述，拟穴青蟹幼蟹饲料中添加蛹肽粉和蝇蛆粉促进幼蟹生长，提高其免疫力具有切实可行性。

| Abstract: | Abstract: In order to investigate the effect of pupa peptide powder or maggot powder on the growth performance, body composition and digestive enzyme activities of juvenile mud crab (Scylla pseudoaculea), the basic diet was supplemented with 10% pupa peptide powder or maggot powder to feed the juvenile mud crab for 45 days. The results showed that: weight gain and specific growth rate of the juvenile mud crab in pupa peptide diet group were significantly higher than those in basic diet group and maggot diet group (P<0.05), whereas survival rate of the juvenile mud crab in pupa peptide diet group was significantly higher than those in basic diet group (P<0.05); Water content of the juvenile mud crab in basic diet group was significantly lower than that in pupa peptide diet group and maggot diet group (P<0.05), whereas crude protein content of the juvenile mud crab showed the opposite result (P<0.05). Crude lipid content of the juvenile mud crab was: basic diet group > maggot diet group > pupa peptide diet group (P<0.05); Protease and amylase activity of the juvenile mud crab was: basic diet group < maggot diet group < pupa peptide diet group (P<0.05), and lipase activity of the juvenile mud crab in pupa peptide diet group and maggot diet group was significantly higher than that in basic diet (P<0.05). In conclusion, we indicate that it is feasible and safe to add pupa peptide powder or maggot powder to the diet of juvenile mud crab. |
