On Application of Trace Mineral in Different Forms to Compound Feed for Penaeus chinensis

研究了不同剂型微量元素对中国对虾增重率、成活率、消化率及微量元素在肌肉中积累的影响。增重率以有机态的Ｃａｒｂｏｓａｎ（３０×１０－６）和蛋氨酸资合物（３０×１０－６）为最好，有机态微量元素的增重率高于无机微量元素。对虾对不同剂型的微量元素消化吸收率不同，以Ｃａｒｂｏｓａｎ（３０×１０－６）和蛋氨酸螫合物（３０×１０－６）为最好。维生素Ｃ与微量元素共存时受到破坏，这种现象为本实验首次发现。

The paper reported the study result on adding trace minerals in different forms to the compound feed for prawns,Penaeus chinensis,to exert an influence on body weight increasing rate,survival rate,digestive rate as well as accumulation of trace element in muscle. The body weight increasing rate is the highest of prawns fed on diets added with Carbosan(30×10-6)and methionine mineral chelate (30×10-6 )in organic forms. The prawns fed on diet added with organic trace minerals increase they weight higher than those added with inorganic trace minerals. The prawn fed on diet added with different forms of trace mineral has different digestibility. The forms of methionine mineral chelate (30×10-6)and Carbosan (30×10-6 )are the best forms. The mixture of Vitamin C and different forms of trace mineral can make Vit. C destroyed. This phenomenon is first found in the experiment.
