摘要
在基础饲料中添加0.5%、1.0%和2.0%的复方中草药制剂,连续投喂56 d后,通过测定供试罗氏沼虾(Macrobrachium rosenbergii)的生长性能、血细胞的吞噬活性、血清酶活性、酚氧化酶活性,比较了复合中草药制剂对罗氏沼虾促生长及非特异性免疫功能的影响。结果显示:饲料中添加0.5%的复方中草药制剂对罗氏沼虾的生长影响显著(P〈0.05),添加1%和2%的中草药制剂对罗氏沼虾的血细胞的吞噬活性、溶菌酶活力、酚氧化酶活力影响极显著(P〈0.01)。用嗜水气单胞菌攻毒7 d显示试验组免疫保护率高达44.7%~59.8%。因此,从促生长、提高免疫力和经济角度3方面考虑,建议添加剂量为1.0%为宜。
The diet was made by adding Chinese herbal medicines in the formulated diet for common shrimps according to the portion of 0. 5% , 1.0% , 2. 0% , and was fed to Macrobrachium rosenbergii tor 56 days. The effect of Chinese herbal medicines on growth and nonspecific immunity was studied by measuring the growth performance, phaogoeytic activity, lysozyme, phenoloxidase in M. rosenbergii. The results showed that the addition of 0. 25% Chinese herbal medicines in diet had significant effect on the growth( P 〈0. 05 ) , the addition of 1% and 2% Chinese herbal medicines in diet had extremely significant effect on the phaogocytic activity, lysozyme, phenoloxidase( P 〈 0. 01 ). With Aeromonas hydrophila infection for 7 d, it showed that the immunity protective ratio of test groups reached 44. 7% -59. 8%. So it suggested 1.0% addition was suitable from the aspects of growth, immunity and economy.
