【摘 要】

：

以草鱼为研究对象,通过降低草鱼基本日粮里的蛋白质水平,提高脂肪水平,研究日粮对草鱼肌肉营养成分的影响.选取健康度和规格一致的草鱼360尾,随机分成两组:对照组和试验组.每组180尾,分3个水平,每个水平60尾.对照组饲喂基础日粮,试验组饲喂高脂肪水平的日粮,预试验5 d,正式试验56 d.试验结束后对草鱼的肌肉营养成分进行测定.结果显示,验组的草鱼肌肉的水分、粗蛋白、粗灰分和对照组的相比无显著差异(P>0.05);试验组的粗脂肪水平显著高于对照组(P<0.05);以上结果说明在草鱼的基础日粮中降低蛋白质水

渔用中草药饲料添加剂的发酵工艺优化

为提升渔用中草药应用效果,本研究控制中草药发酵过程中的含水量、接菌量、发酵时间和发酵温度,采用单因素试验和4因素3水平的正交试验对发酵工艺进行优化,以蒽酮-硫酸法测定中草药发酵后的多糖含量,最终确定该中草药的最佳发酵工艺为含水量50％,接菌量4％,发酵温度33℃,发酵时间72 h.本研究可为渔用中草药的发酵应用提供参考.
