The impact of Mucuna pruriens (L.) seed meal diet on growth performance, innate immune response, and disease resistance in Oreochromis mossambicus against Aeromonas hydrophila is reported for the first time. Infected O. mossambicus was fed with 2 g kg, 4 g kg, and 6 g kg of M. pruriens seed meal diets significantly increased initial body weight (IBW) and final body weight (FBW) over control, for a period of 4 weeks. At 4 g kg and 6 g kg the enriched diet significantly (P < 0.05) enhanced the survival rate, weight gain (WG), protein efficiency ratio (PER), specific growth rate (SGR), feed conversion ratio (FCR), and feed efficiency (FE) when compared to the control; besides, from weeks 2-4 these diets significantly (P < 0.05) enhanced the complement activity, phagocytic activity, respiratory burst activity, and lysosome activity. On being fed with 4 g kg and 6 g kgenriched diets the cumulative mortality was lower (10% and 12%) than with 2 g kg diet (24%). The present investigation suggests that the enriched diet at 4 g kg and 6 g kg improved the growth performance more than that of the control and negative control; it also positively enhanced the innate immunity and disease resistance against A. hydrophilla in O. mossambicus. Hence M. pruriens can be used as a feed additive to stimulate immunity for effective production of economically valuable freshwater fish, O. mossambicus.
首次报道了食用黎豆（L.）种子粉对奥利亚罗非鱼生长性能、先天免疫反应和抗嗜水气单胞菌能力的影响。感染的奥利亚罗非鱼连续 4 周摄食 2、4 和 6 g/kg 的黎豆种子粉，与对照组相比，初始体重（IBW）和终末体重（FBW）显著增加。在 4 和 6 g/kg 时，与对照组相比，富集饲料显著（P < 0.05）提高了存活率、增重（WG）、蛋白质效率比（PER）、特定生长率（SGR）、饲料转化率（FCR）和饲料效率（FE）；此外，从第 2 周到第 4 周，这些饲料显著（P < 0.05）提高了补体活性、吞噬活性、呼吸爆发活性和溶酶体活性。摄食 4 和 6 g/kg 富集饲料的累积死亡率（10%和 12%）低于 2 g/kg 饲料（24%）。本研究表明，与对照组和阴性对照组相比，4 和 6 g/kg 的富集饲料更能提高生长性能；还能积极增强奥利亚罗非鱼的先天免疫和抗嗜水气单胞菌能力。因此，黎豆可用作饲料添加剂，刺激免疫，有效生产具有经济价值的淡水鱼奥利亚罗非鱼。
