Weight loss in slaughter weight and Primal Cut (PC) of Bali pigs in additional feed base from fermented broiler farm by-products

Abstract

The research aims to determine the loss of slaughter weight and primal cuts (PC) in Bali pigs to given feed based on fermented broiler farm by-products (BBP). The research used a completely randomized design, with three treatments and five replications (3 x 5). The treatment is, A: Ration with 0% broiler farm by-product, B: 12% broiler farm by-product, C: 24% broiler farm by-product. Using 15 Bali pigs in the grower phase with an average weight of 13.30±0.79 kg. Research variables: Loss of slaughter weight and primal cuts (Boston butt, picnic shoulder, loin, bacon belly, and ham). The results of the research: Addition of 24% BBP (C) to the feed caused a reduction in slaughter weight of up to 4.7%, carcass weight was 4.8% lower than control (A) (p<0.05) and caused a reduction in slaughter weight of up to 18.7% higher than the control group (p<0.05). Treatment group C (24% BPB) caused a decrease in carcass weight (p<0.05), and was only followed by a decrease in ham weight in the grower phase of Bali pigs. The conclusion is: By adding BBP up to 24%, it can reduce slaughter weight, carcass weight and ham weight, as well as increase the slaughter weight loss of Bali pigs in the grower phase.
