The objective of this study was to evaluate, in purified diets, the effects of different levels of crude fiber on the apparent digestibility and gastrointestinal transit rate in Nile Tilapia. Five circular fishbowls (250 L) with a closed system of water filtering, replenishment and heat for feeding and five digestibility fishbowls with individual filtering replenishment and heat system were used. Thirty-two fishes, averaging initial weight of 30.65 ± 0.50 were used. A completely randomized design with five levels of crude […]
