Abstract

This study was conducted to evaluate the potential of sweet potato Ipomoea bata-tas powder (IbSPP), hot-water extracts (IbSPHWE) and crude ethanolic extracts (IbSPCEE) as growth pro-moter and immunoenhancer for tilapia cultured in hapa nets. Fish were divided ran-domly into four Treatments: T1 (control group) was fed a practical diet (PD) while T2, T3 and T4 were fed PD + IbSP powder (P), PD + IbSP hot-water extract (HWE), PD + IbSP Crude Ethanol Extracts (CCE), respective-ly. The growth indices and haematological profile of cultured fish were recorded after four months of feeding experiment. The final weight, weight gain, specific growth rate, condition factor, FCR, PER, FER were significantly higher in fishes that re-ceived PD +IbSPHWE than those that received either PD, PD + IbSPCEE or PD+ IbSPP only. The same trend was observed with the RBC, Hb, HCT, WBC and the PLT and its indices. The study has demonstrated that in-corporation of the hot-water extracts of I. batatas could improve the growth perfor-mance and increase immu-nocompetence of O. nilot-icus as evidenced by im-proved haematological pro-file.

饲粮中添加甘薯芽改善了罗非鱼生长性能和血液特性

本试验旨在评价甘薯粉(IbSPP)、热水提取物(IbSPHWE)和粗乙醇提取物(IbSPCEE)对罗非鱼hapa网养殖的促生长剂和免疫增强剂的作用。将试验鱼随机分为4个处理:T1组(对照组)饲喂实用饲料(PD)， T2、T3和T4组分别饲喂PD + IbSP粉(P)、PD + IbSP热水提取物(HWE)、PD + IbSP粗乙醇提取物(CCE)。饲养试验4个月后，记录养殖鱼的生长指标和血液学特征。PD+ IbSPHWE组的最终体重、增重、特定生长率、条件因子、FCR、PER、FER均显著高于PD、PD+ IbSPCEE或PD+ IbSPP组。RBC、Hb、HCT、WBC、PLT及其指标均有相同的变化趋势。本研究表明，牛蒡热水浸提液可改善牛蒡的血液学指标，提高其生长性能和免疫能力。
