Replacement of broiler liver by fish meal and soy protein concentrate in diets for silver catfish (Rhamdia quelen) post-larvae

| Sumario: | Muscular growth in fish is influenced by diet quality, mainly the protein sources and amino acids balance. A feeding trial was conducted for a period of 28 days. Muscle growth and histology of Silver catfish post-larvae was evaluated. The diets tested were partial and total replacement of broiler liver by fish meal and soybean protein concentrate (basal, 15FM, 30FM, 15SPC and 30SPC). The basal diet consisted mainly of fresh poultry liver plus sugarcane yeast. After the feeding test, the fish fed with 15FM diet presented higher growth (P < 0.05) than the post-larvae fed with the other diets. The muscle development was performed in post-larvae-fed diets 15FM and 30SPC. Higher diameter and total number of fibres were found in fish fed diet 15FM diet (P < 0.05). The replacement of 50% of the broiler liver by fishmeal provided a good diet for Rhamdia quelen post-larvae. |
