利用药浴法、注射法及药饵法研究了麦胚凝集素(WGA)促进对虾抗病力的效果。经肌肉注射法感染实验证明三种给药方法均可提高对虾的存活率,其中以药饵法(20mg/kg含量、喂养28d)效果较好,对虾存活率提高17％。表明利用药物促进对虾免疫系统功能,提高对虾抗病能力是一条可行的途径。 The effects of wheat germ agglutinin (WGA) on the disease resistance of shrimp were studied by means of medicinal bath, injection and bait. Infection experiments with intramuscular injection proved that the three administration methods could improve the survival rate of shrimp, among which the bait method (20mg / kg content, feeding 28d) is better, the survival rate of shrimp increased by 17%. It shows that the use of drugs to promote the immune system of shrimp and improve shrimp resistance to disease is a viable approach.
