Pengaruh Penambahan Aditif Pakan Berupa Kulit Singkong dan Bakteri Asam Laktat terhadap Pemanfaatan Protein Ransum Ayam Broiler

Abstract

This research was aimed to determine the effect of addition of feed additives of cassava peel and lactic acid bacteria in the ration on protein utilization of broiler chicken. The material used in this study was 144 broiler chickens 10 days old, unsexed, with an average weight of 198.59 ± 5.82 g. Feed rations provided contained 18.9% protein and 3,044.9 Kcal of metabolizable energy. This research used a completely randomized design (CRD), 4 treatments and 6 replications, each experiment unit was filled with 6 chickens. The treatments applied were feed additives as follows T0: basal ration; T1: basal ration + 50 ml/kg; T2: basal ration + 100 ml/kg; T3: basal ration + 150 ml/kg. The parameters observed included protein consumption, protein digestibility, nitrogen retention and protein mass of meat. The research data were analyzed by variance with the F test, followed by Duncan's test at a probability of 5%. The results showed that the addition of feed additives had no significant effect (P> 0.05) on protein consumption, protein digestibility, nitrogen retention, and lean protein mass. The conclusion of this research is the addition of feed additives in the form of cassava peel and lactic acid bacteria up to 150 ml/kg of feed have not been able to increase the diet on protein utilization of broiler.
