Performance of Quail (Coturnix Japonica) Fed Diets with Fish Meal Substituted by Catfish Offal Flour (Pangaius hypopthalmus)

Catfish offal flour (COF; Pangaius hypopthalmus) has the potential to replace fish meal (FM) due to its high crude protein content. The present study aimed to investigate the effects of substituting FM with COF in basal diets on food intake (FI), body weight gain (BWG), and feed conversion ratio (FCR) in quails. A total of 100 male quails were randomly assigned to five treatment groups, each with four replicates. The treatment groups were fed with basal diet + 0% COF and 100% FM (T0), basal diet + 25% COF and 75% FM (T1), basal diet + 50% COF and 50% FM (T2), basal diet + 75% COF and 25% FM (T3), and basal diet + 100% COF and 0% FM (T4). Feed intake, BWG, and FCR were measured from 0 to 35 days of age. The findings indicated that substituting FM with COF up to 100% did not significantly affect FI, BWG, and FCR. It can be concluded that COF has the potential to replace FM in basal diets while maintaining performance in quails.
