Growth and productivity of Kampung chicken fed with different protein levels

Abstract

This research aimed to study the growth and productivity of kampung chicken fed with different protein level. Kampung chickens were randomly assigned to a completely randomized design with 4 treatments and 10 replications. The treatments were Ration with 14% protein content (A),  Ration with 16% protein content (B), Ration with 18% protein content (C)  and Ration with 20% protein content (D). The variables observed were body weight, weight gain, consumption, FCR, digestibility, egg production, percentage of hatched eggs and income over feed. Data were analyzed by variance and if there was a significant difference between treatments (P<0.05), it was continued with Duncan's multiple distance test. The results showed that the protein level of the diet 18% significantly (P<0.05) increased weight gain, egg production, and better feed use efficiency. The provision of 20% protein gave the same effect (P>0.05) on growth, production. Income over feed costs tended to be lower in the protein level of the 20% than 18%.  It can be concluded that kampung chickens reared in enriched cages with a ration protein level of 18% and metabolic energy of 2850 kcal/kg showed the best performance in terms of growth, production, hatch percentage, and income over fee cost
