The impact of Cucurbita mixta (L.) seed meal enriched diet on growth performance, innate immune response, and disease resistance in Oreochromis mossambicus against Aeromonas hydrophila was investigated. O. mossambicus was fed with 2 g kg, 4 g kg, and 6 g kg C. mixta seed meal diets for a period of 4 weeks. The results indicated that C. mixta seed meal diets at 4 g kg and 6 g kg significantly (P < 0.05) enhances the survival rate, weight gain (WG), protein efficiency ratio (PER), specific growth rate (SGR), feed conversion ratio (FCR), and feed efficiency (FE) from weeks 1-4 when compared to control. C. mixta seed meals administered as feed supplements significantly (P < 0.05) enhanced the complement activity, phagocytic activity, respiratory burst activity, and lysosome activity in infected fish fed with 4 g kg and 6 g kg of C. mixta seed meal enriched diet from weeks 2-4. The cumulative mortality was lower in the fish fed with 4 g kg and 6 g kg of C. mixta seed meal enriched diets (15% and 18%) than with 2 g kg diet (26%). The present investigation suggested that C. mixta seed meal enriched diet at 4 g kg and 6 g kg enhance the better growth performance, innate immunity, and disease resistance against A. hydrophilla in O. mossambicus.
研究了富含南瓜属杂交种(L.)籽粕的日粮对莫桑比克罗非鱼生长性能、先天免疫反应及抗嗜水气单胞菌抗病力的影响。给莫桑比克罗非鱼投喂2 g/kg、4 g/kg和6 g/kg南瓜属杂交种籽粕日粮,为期4周。结果表明,与对照组相比,4 g/kg和6 g/kg的南瓜属杂交种籽粕日粮在第1 - 4周显著(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)。从第2 - 4周起,作为饲料补充剂投喂的南瓜属杂交种籽粕显著(P < 0.05)提高了感染鱼的补体活性、吞噬活性、呼吸爆发活性和溶酶体活性,这些鱼投喂的是富含4 g/kg和6 g/kg南瓜属杂交种籽粕的日粮。投喂4 g/kg和6 g/kg富含南瓜属杂交种籽粕日粮的鱼的累积死亡率(分别为15%和18%)低于投喂2 g/kg日粮的鱼(26%)。本研究表明,4 g/kg和6 g/kg富含南瓜属杂交种籽粕的日粮能提高莫桑比克罗非鱼的生长性能、先天免疫力及对嗜水气单胞菌的抗病力。
