Utilization of Terminalia catappa L. leaf extract and orange (Citrus cinensis) waste as natural feed additives to improve performance, productivity, and meat quality of broiler chickens

Abstract

Feed additives such as phytobiotic feed additives originating from local waste materials which are abundantly available can be used to support livestock productivity. One of the wastes that is widely available and can be used as a feed additive for poultry is Terminalia catappa L. leaf extract and orange (citrus sinensis) waste. This research aims to find local natural ingredients that are abundantly available and can be used as feed additives for broiler chickens. The research will be carried out in vivo on 252 broiler chickens with a design of 4 treatments and 7 replications with 9 chickens per replication. T0 (control, without administration of a mixture of extract and orange waste); T1 (Giving 3% mixture of Terminalia catappa L. leaf extract and orange waste); T2 (Giving 5% mixture of Terminalia catappa L. leaf extract and orange waste); and T3 (Administration of a 7% mixture of Terminalia catappa L. leaf extract and orange waste). Water and feed consumption, body weight gain, feed conversion ratio, IOFC, carcass traitt, meat moisture, meat crude protein and crude fat of broiler chicken were not significant  (P > 0.05) among treatment. Phytobiotic feed additive from Terminalia catappa leave extract and orange waste in drinking water did not enhance performance, carcass trait, and meat quality of broiler chicken.
