Penggunaan Kombinasi Ekstrak Daun Kersen (Muntingia calabura) dan Daun Sirsak (Annona muricata L.) sebagai Antioksidan terhadap Karkas Ayam Broiler

Abstract

Antioxidants are molecules that can slow down or prevent the oxidation process of other molecules. This study aims to determine the effect of the combination of Kersen Leaf (KL) and Soursop Leaf (SL) extracts as antioxidants on Slice Weight (SW), Carcass Weight (CW) and Carcass Percentage (CP) of broiler chickens. This research was conducted on Jl. Mekar Jaya No 38 Medan Selayang, North Sumatra in June – August 2023. The design used in this study was a Complete Randomized Design (CRD) with 5 treatments and 5 repeats. Each repetition consists of 5 broiler chickens aged 35 days. The treatment consisted of P0 (without extract), P1 (KL extract 9%), P2 (SL extract 9%), P3 (KL extract 6% + SL extract 3%) and P4 (KL extract 3% + SL extract 6%). The parameters observed were SW, CW and CP. The results showed that the use of a combination of KL and SL extracts as antioxidants had a real effect on SW and CW with an average of 1491.67-1773.60 g / head and 1067-1267 g / head respectively. However, it did not have a real effect on CP with an average of 71.16%-72.14%. The best results are found in the P3 treatment.
