选取同一放养批次健康的凡纳滨对虾,随机分为5组。第1组为空白对照组,饲喂基础饲料,其他4组为三七总皂苷组,分别添加100、200、400和800mg/kg三七总皂苷试验饲料。每组3个重复,每重复40尾虾,试验期40d。结果表明:在饲料中添加适宜水平三七总皂苷能显著提高凡纳滨对虾的增重率和特定生长率,降低饲料系数,提高蛋白质效率,添加不同水平三七总皂苷对凡纳滨对虾肌肉粗蛋白、粗脂肪、灰分和水分含量无显著影响。
Select the same stocking batches of healthy Litopenaeus vannamei, were randomly divided into 5 groups. The first group was blank control group fed with basal diet, the other four groups were Panax notoginseng saponins group, 100, 200, 400 and 800 mg / kg of total saponins of Panax notoginseng were added respectively. Each group of three replicates, 40 shrimp per repetition, the test period 40d. The results showed that adding appropriate levels of Panax notoginseng saponin to feed could significantly increase the weight gain rate and specific growth rate of Litopenaeus vannamei, reduce the feed efficiency, increase the protein efficiency, and add different levels of Panax notoginseng saponins to the muscle Crude protein, crude fat, ash and moisture content had no significant effect.
