Abstract

Abstract Different inclusion levels of cockroach meal Nauphoeta cinerea (CM) were investigated in diets for tilapia (Oreochromis niloticus) reared in biofloc systems in substitution of the soybean meal. Five treatments were evaluated (0, 5, 10, 15 and 20% of CM inclusion) using three experimental units per treatment. The experiment lasted for five weeks with units stocked with 10 juveniles (3.00±0.25 g) per replicate. Water quality, zootechnical performance, bacteriological profile, and proximate composition were analyzed and monitored. Zootechnical data was submitted to a regression analysis up to second order. No differences were verified regarding feed conversion, survival and productivity. The CM presented high protein levels (66.84%), high estimated gross energy (5270 kcal kg−1), low lipids (6.07%) and mainly long-chain saturated fatty acids. Different bacteriological profiles were identified including species which may be potentially pathogenic and responsible for degrading organic matter. The overall results indicated that it is possible to include CM up to 10% in diets for tilapia juveniles raised in biofloc systems.

尼罗罗非鱼的生物定位技术和蟑螂（灰尾蠊）虫粉饲料：动物技术性能、基本成分和细菌特征

摘要以罗非鱼（Oreochromis niloticus）为试材，采用生物絮凝体系代替豆粕，研究了罗非鱼日粮中蟑螂粉灰蝶（CM）的不同包合水平。每个处理使用三个实验单元评估五个处理（CM包含的0%、5%、10%、15%和20%）。实验持续了五周，每个重复单元储存10只幼崽（3.00±0.25克）。分析并监测了水质、动物技术性能、细菌概况和附近成分。动物技术数据被提交到二阶回归分析。在饲料转化率、存活率和生产力方面没有差异。CM表现出高蛋白质水平（66.84%）、高估计总能量（5270 kcal kg−1）、低脂质（6.07%），主要是长链饱和脂肪酸。鉴定了不同的细菌特征，包括可能具有潜在致病性并负责降解有机物的物种。总体结果表明，在生物絮凝系统中饲养的罗非鱼幼鱼的日粮中可以添加高达10%的CM。
