The effect of protein levels in rations on the percentage of internal organs of Local Bali pigs

Feed quality is one of the factors that affect internal organs. The purpose of this study is to determine the effect of protein levels in the rations on the percentage of internal organs of local bali pigs. The experimental design used was a completely randomized design (CRD) consisting of 4 treatments and 4 replications. The four treatments are: P1 (ration with 14% protein level), P2 (ration with 16% protein level), P3 (ration with 18% protein level) and P4 (ration with 20% protein level). The observed variables include: percentage of heart, lung, liver, kidney, stomach, small intestine, and large intestine. The results showed that the administration of protein levels from 14% to 16%, 18% and 20% led to an increase in the percentage of local bali pig stomachs by 9.80%, 5.88%, and 13.72% respectively, while the percentages of heart, lung, liver, kidney, small intestine, and large intestine were the same among the treatments. It can be concluded that the provision of rations with a protein level of 14%; 16% 18%; and 20% can increase the percentage of the local bali pig stomach, but it does not affect the percentage of the heart, lungs, liver, kidneys, small intestine, and large intestine.
