摘要
报道了在以花生饼、鱼粉、玉米粉和麸皮为基本原料,加入不同浓度梯度的锰所配制的人工饵料饲喂中国对虾(Penaeus chinensis),对其增长、增重和存活率均无明显的影响,但添加适量的锰对其肝胰脏申的羧肽酶A具有激活作用。据此认为,利用上述原料生产的配合饵料可以不添加锰,但饵料中即使含锰量较高,对对虾的生长、成活也没有害处。
Prawn (Penaeus chinensis O'sbeck)were fed diets containing peanuts cake, fish meal, corn meal and wheat bran, each tested in combination with six levels supplemental manganese, O, 10, 20, 40, 80 or 160×10-6. The results of the present study showed that there was no growth of survival of dietary manganese suplementation on growth of survival of the animal, but proper content of supplemental manganese could activate carboxypeptimanganese to the diets is not necessary. The manganese content in the raw materials of the diets is enough for the penaeid shrimp. However higher level of manganese in the diet may not produce harm to the animal.
