Abstract

IKHSAN GUSTIANDA. The Effect of Adding Black Cumin (Nigella sativa) Extract to Drinking Water on Slaughter Weight, Carcass and Non-Carcass Percentage of Broiler Chickens. (Supervised by USMAN BUDI and FUAD HASAN). This study aims to determine the effect of adding Black Cumin (Nigella sativa) extract to drinking water on slaughter weight and carcass and non-carcass percentage of Broiler chickens. This research was conducted from May to July 2024 at the Greenhouse and Field Laboratory of the Faculty of Agriculture, Universitas Sumatera Utara. The design used in this study was a Completely Randomized Design (CRD) with 4 treatments and 5 replications. The treatments consisted of the addition of Black Cumin extract (P0=0%; P1=1%; P2=2%; and P3=3%). The parameters observed were slaughter weight, carcass and non-carcass percentage, carcass percentage, and non-carcass percentage. The results showed that the addition of extract in broiler drinking water did not have a significant effect (P>0.05) on carcass weight, non-carcass weight, carcass percentage and non- carcass percentage, while the addition of Black Cumin extract had a significant effect (P<0.05) on slaughter weight.
