Abstract

ABSTRACT: An eight-week feeding trial was conducted to evaluate the supplementation of pineapple waste extract (PWE) at levels of 0%, 1%, 2%, and 3% on growth performance of Nile tilapia (8.76 ± 0.17 g) for 8 weeks. PWE supplementation improved pepsin digestibility significantly but not protein digestibility. Thus, fish fed PWE showed better growth than those fed the control feed. The fish fed the feed supplemented with 1% PWE resulted in the optimum protein digestibility, growth, and feed utilization (P < 0.05). No significant differences among dietary treatments were found for free ammonia and total nitrogen excretion (P > 0.05).
