Abstract:
Background: The research was carried out in the Poultry Cage of the Faculty of Animal Husbandry, Padjadjaran University, Jatinangor, Sumedang. The research objective was to determine the effect and obtain the appropriate level of use of jengkol peel extract in a ration that produces an optimal balance of protein efficiency in broiler chickens.
Materials and Methods: The study used 100 one-day-old broiler chickens (DOC) of the Cobb strain which were placed in 20 cage units for five weeks. The study used an experimental method with a completely randomized design (CRD) consisting of 4 ration treatments, namely R0 (basal ration without jengkol peel extract), and rations with the addition of jengkol peel extract, namely R1 (0.01%), R2 (0.02%), and R3 (0.03%), each treatment was repeated five times. The variables observed were body weight gain, protein consumption, and protein efficiency balance. Data were analyzed using variance and continued with Duncan's Multiple Range Test.
Results: The results of the statistical analysis, of the balance protein efficiency (BPE) for broiler chickens, found that between treatments there was no significant difference (P>0.05) in BPE. However, was a significantly different (P<0.05) in body weight gain. The addition of jengkol peel extract (JPE) to the ration resulted in a chicken body weight gain that was as great as the ration treatment without JPE (R0), except the ration with the addition of 0.02% JPE (R2) resulted in a significantly higher broiler body weight gain than the treatment other. This is because the content of the active compound JPE is at the right dose so that it can function optimally.
Conclusions: The use of jengkol peel extract in rations influences body weight gain, but does not affect protein consumption and protein efficiency balance. The use of jengkol peel extract at a level of 0.02% resulted in an optimal balance of protein efficiency in broiler chickens.
