dc.description.abstract | Fishmeal (FM) was substituted with soybean meal (Glycine max) (SBM) and bambaranut
meal (Voandzeia subterranea) (BNM) in 10 experimental African catfish, Clarias gariepinus, diets. Feed
formulation was designed using mixture model. The inclusion level of the three protein ingredients
varied between 0% and 60%. Remaining 40% comprised of basal ingredients kept constant for all 10
feeds. African catfish of average initial weight 35.2 ± 0.9 g were fed with one of the treatment diets
for 28 days. The protein:lipid ratios of the diets (range 1.5–3.4:1) were used in evaluating the feed
utilization and growth of the fish. We found that catfish performances were mainly depending on
ingredients and not the ratio itself. The protein:lipid ratios in the diets made of plant ingredients
were high but SGR was low. Specific growth rate (SGR) increased with the increase of feed FM
content, being ca. 5% day−1 with 60% FM diet but ca. 2% day−1 at both 60% BNM and 60% SBM
diets. SGR was similar (3.5% day−1) with diets of 30% BNM or SBM inclusion with 30% FM. Feed
conversion ratio increased from below 0.6 of the 60% FM diet up to 1.5 (60% SBM) and 1.7 (60%
BNM). Protein efficiency ratio decreased linearly with increasing FM substitution, but protein
productive value (PPV) was similar for catfish fed 60% FM diet and its 50% substitution with BNM
or SBM. These results suggest that protein:lipid ratio cannot be used in assessing nutritional
performance if the source of feed ingredient vary widely. However, these results suggest that BNM
can partly substitute FM and completely replace SBM in the diets of African catfish. | |
