Slaughter weight, carcass and giblets percentage of broiler chicken with addition of Indigofera zollingeriana leaves in feed

Abstract

Abstract This study was aimed to study the addition effect of Indigofera zollingeriana leaves flour in feed on slaughter weight, carcass and giblets percentage of broiler chicken. This research used completely randomized design (CRD) with 4 treatments and 4 replications. The treatments were P0 = control, P1 = feed containing 2% indigofera leaves flour, P2 = feed containing 4% indigofera leaves flour, and P3 = feed containing 6% indigofera leaves flour. The measured variables in this research were slaughter weight, whole carcas weight, carcas percentage, heart percentage, gizard percentage, liver percentage, and abdominal fat percentage. The data obtained were analyzed using varian analysis based on completely randomized design and continued using Duncan’s Multiple Range Test. The result showed that addition of 2–6% Indigofera zollingeriana leaves flour in broiler feed did not give any significant effect on slaughter weight, whole carcass weight, carcas and giblets percentage, but gave a significant effect (P<0.05) on the abdominal fat percentage of broiler chicken. The addition of 6% indigofera leaves in broiler feed could reduce the abdominal fat content.
