Defatted Rice Bran as a Protein Source in Catfish Feeds
A defatted rice bran (DRB) product was evaluated as a potential ingredient in practical channel catfish (lctalurus punctatus) feeds by partial substitution of control feed ingredients. Fingerlings in aquaria were fed I of 4 feeds: 0 (control) - a standard commercial feed, 1 - DRB replaced regular rice bran, 2 - DRB replaced some com, soybean meal, and rice bran, 3 - DRB replaced some com, fish meal, and rice bran. There were no significant (P > 0.05) differences in survival or feed conversion among fish fed the 4 feeds, but fish fed feed 2 had a greater weight gain than fish fed feed 0...
