Effectiveness of Shallot Peel Powder (Allium ascalonicum L.) as Feed Additive on Weight and Broiler Carcass Components

Abstract

The research was conducted with the aim of determining the effectiveness of shallot peel flour on the weight of broiler carcasses and carcasses. The research was carried out from July – September 2024 at the Nutrition and Animal Food Laboratory of Universitas Brawijaya and in the internal cage of PT Ciomas Adisatwa. The research was carried out experimentally using a Complete Random Design with 6 treatments and 5 replicates, each experimental unit had 12 broilers so that the total number of chickens used was 360. The treatment given was P0 (+): Commercial feed, P0 (-):Commercial feed + zinc bacitracin antibiotic 0.1%, P1: Commercial feed + shallot peel flour 0.25%, P2: Commercial feed + shallot peel flour 0.5%, P3: Commercial feed + shallot peel flour 0.75%, and P4: Commercial feed + shallot peel flour 1%. The data is analyzed using Analysis of Variance and continued using the Least Significant Different if there is a real difference. The results showed that the addition of onion peel flour had a significant effect (P<0.05) on the weight of the carcass with the best treatment obtained P3 of 1,960.40 g/head and no significant effect (P>0.05) on the weight of the carcass pieces. The conclusion of this study is that shallot peel flour can be used as a ration additive to increase the weight of broiler carcasses by 0.75%.
