摘要:用4个梯度可溶性糖添加量(15%,25%,35%,45%)的饲料,饲养相同龙虾60天,并测定其生长和免疫指标,还有在不同饲料可溶性糖含量下肝脏糖原和脂肪含量,旨在找出一种最适于龙虾饲料的添加可溶性糖。实验结果表明:25%添加可溶性糖作为龙虾饲料效果最佳。

Abstract: The same lobsters were been keeping for 60 days with different feed content of soluble sugar four gradient additives (15%,25%,35%,45%) to statistics the effect of its growth and immune parameters, as well as in soluble sugar content under different feed and fat content of liver glycogen.The purpose is to find the most suitable additive quantity of soluble sugar of the lobster feed. The results showed that: 25% Add soluble sugar as the best lobster feed.

国内外虽然对螯虾野外食性、不同营养物质的需要及环境对螯虾进食的影响的食性特征有一定的研究,但高效专用的克氏原螯虾饲料还没有上市,最适营养成分至今尚无人探索。众所周知,摄入糖过高,影响对其他营养成分如蛋白质、维生素、矿物质的摄入。另一方面,需要消耗多种维生素和矿物质,因此,经常吃糖会造成维生素缺乏、缺钙、缺钾等营养问题。同时糖摄入过多会转化为脂肪。所以会造成脂肪肝以及减少产量。本研究旨在找出龙虾饲料的最适可溶性糖添加量,提高饲养的效率,降低成本, 提高经济效益。
