Growth performance, nutrient utilization and body indices of Nile tilapia (Oreochromis niloticus) fingerlings fed local feed ingredients

Sammanfattning

A 10-week trial was conducted to evaluate growth performance, feed utilization, and somatic indices of Nile tilapia (Oreochromis niloticus) fingerlings fed five diets based on local feed protein ingredients (kidney bean leaf meal (KBLM), spent brewer’s grain (SBG), spent brewer’s yeast (SBY), sweet potato leaf meal (SPLM), and wheat middlings (WM) and a fishmeal-based control diet (CD). The experimental diets were formulated to be iso-nitrogenous and iso-energetic, with 27-50% of fishmeal in CD replaced (‘as is’ basis) with test ingredient. Initial average body weight of individual fish was 28.9±1.88 g and final body weight (FBW) was 60.2±2.81 g. Weight gain (WG) and FBW were highest (p
