通过15周饲养试验测定了斑节对虾核黄素的需要量。幼对虾(平均始重 0.13±0.05克)饲喂添加 7种水平核黄素的纯制日粮(0、8、12、16、20、40和 80mg/kg日粮),虾成活率、饲料转化率和增重均无显著差异,虾体内核黄素浓度随核黄素添加增加而升高,血淋巴中谷胱甘肽还原酶的活性系数不是虾核黄素状况的一种敏感和特异性指示剂。根据虾体内核黄素浓度曲线转折点图形分析发现,斑节对虾日粮核黄素需要量为 22.3mg/kg日粮。饲喂未添加核黄素日粮(核黄素水平为0.48mg/kg日粮)15周的虾,其缺乏症出现:色彩变淡、应激、体节间表皮突出和短头矮小。
The requirement for riboflavin of P. monodon was determined by a 15-week feeding experiment. Young shrimp (mean starting weight 0.13 ± 0.05 g) were fed a pure diet (0, 8, 12, 16, 20, 40 and 80 mg / kg diet) supplemented with seven levels of riboflavin, There was no significant difference in conversion rate and weight gain. The concentration of riboflavin in shrimp increased with the addition of riboflavin, and the activity coefficient of glutathione reductase in hemolymph was not a sensitive and specific Indicator. According to the graphical analysis of turning point of riboflavin concentration curve in shrimp body, riboflavin requirement of Penaeus monodon diet was 22.3mg / kg diet. Shrimp fed a diet without riboflavin (riboflavin at 0.48 mg / kg diet) for 15 weeks showed a lack of color: light fades, stress, prominence of the epidermis and short and short heads.
