Abstract

Fruit residues represent alternative ingredients that can be included in diets of tambaqui, Colossoma macropomum. This study evaluated the growth performance of tambaqui fed diets containing different levels of guava agroindustrial residue. The experiment was based on a completely randomised design, with 105 fish randomly distributed in 15 plastic 60 L-1 boxes with a water recirculation system. Feeding was carried out to apparent satiety for 45 days, using diets with 0, 50, 100, 150 and 200 g kg-1 inclusion of guava residue. Biometrics were performed every 15 days. Quadratic effect (p < 0.05) was observed for daily feed intake and apparent feed conversion, with optimum levels of 4.86 and 6.05% inclusion of guava residue, respectively. There was no significant difference (p > 0.05) in relation to final weight, weight gain, specific growth rate, hepato-somatic index, survival rate and protein efficiency rate by the dietary treatments. The inclusion of up to 150 g kg-1 of the guava agroindustrial residue in the feed did not compromise the performance of tambaqui juveniles.
番石榴渣对柽柳生长性能的影响
水果残留物代表的替代成分,可以包括在坦巴基,巨像马饲料。本研究评价了在不同水平番石榴农工渣饲料中饲喂坦巴奎鱼的生长性能。该实验基于完全随机设计,将105条鱼随机分布在15个带有水再循环系统的60 L-1塑料盒中。饲喂45 d至表观饱腹,分别添加0、50、100、150和200 g kg-1番石榴渣。每15天进行一次生物识别。日采食量和表观饲料系数均存在二次效应(p < 0.05),番石榴渣添加量分别为4.86%和6.05%时最适宜。不同饲粮处理对末重、增重、特定生长率、肝体指数、成活率和蛋白质利用率均无显著差异(p > 0.05)。饲料中添加高达150 g kg-1的番石榴农业工业残留物不会影响坦巴奎幼鱼的生产性能。
