- Antibiotics that are often added to animal feed have the function of increasing productivity, reducing mortality and improving the efficiency of feed use. The use of antibiotics can leave a residue and endanger health. One way to anticipate this problem is by stopping the use of antibiotics in rations by trying to find natural ingredients that have the same function as antibiotics but do not leave a residue on the products produced. This research was conducted from July to September 2018 at the Experimental Cage of Animal Husbandry Study Program and Laboratory of Nutrition and Animal Feeding, Faculty of Agriculture, Sriwijaya University. The design used was a completely randomized design (CRD) with 5 treatments and 4 replications. Treatment (P1) pineapple waste 100%, (P2) 98% pineapple waste : 2% Indigofera zollingeriana, (P3): 96% pineapple waste : 4% Indigofera zollingeriana, (P4): 94% pineapple waste : 6% Indigofera zollingeriana, (P5): 92% pineapple waste : 8% Indigofera zollingeriana. The parameters observed were dry matter digestibility, crude fiber digestibility and crude protein digestibility in-vitro. The results showed that the addition of supernatant from liquid fermented pineapple waste and leaves of Indigofera zollingeriana into the ration had a significant effect (P <0.05) on the digestibility of crude fiber and crude protein in vitro. Based on the results of the study it can be concluded that the best combination is 92% pineapple waste: 8% Indigofera zollingeriana because it can increase digestibility of crude protein, crude fiber and dry matter.
