The use of fermented feather meal for replacement fish meal in the diet of oreochromis niloticus
Main Article Content
Abstract
The suitability of fermented feather meal (FFM) as a replacement of dietary fish meal protein in the diet for tilapia was evaluated. Five diets were formulated in which fish meal (FM) in the control diet (diet 1) was replaced by FFM in the following percentages: 0/100, 25/75, 50/50 75/25 and 100/0 (FFM/FM). All the diets were contained with 30 % protein. Each diet was proffered to three replicate groups of 60 tilapia (20 per replicate) with average initial body weight 120.0 ± 5.0 g for 12 weeks. Survival was not significantly different among diet formulas (100 %). The individuals fed with 0/100, 25/75 and 50/50 (FFM/FM) did not differ significantly in average weight gain, however, individuals fed with 100/0 (FFM/FM) was significantly poorest than those fed all other diets at the end of experimental periods. The results of the present study indicated that fermented feather meal could be used at 25 % up to 50 % of the diet level for Oreochromis niloticus without compromising growth and feed utilization efficiency. However, it’s appeared to result in a decrease in weight gain and associated growth parameters with high increasing replacement.
