Additional effect of soursop leaf extract fermented through drinking water on joper chicken carcas

The research aims to determine the effect of adding fermented soursop leaf extract (Annona muricata) to drinking water on joper chicken carcasses. The research used a Completely Randomized Design (CRD), with 5 treatments and 4 replications, each experimental unit used 10 Joper chickens so that a total of 200 Joper chickens were used. The treatments in the experiment were: chickens without fermented soursop leaf extract through drinking water (P0), 1% fermented soursop leaf extract (P1), 2% fermented soursop leaf extract (P2), 3% fermented soursop leaf extract (P3). ), administration of 4% fermented soursop leaf extract (P4). The variables observed were the phytochemical content of soursop leaf extract, nutrient digestibility, Joper chicken carcass. The research results showed that the water extract of fermented soursop leaves (Annona muricata) contained phytochemicals phenol, flavonoids, tannins and antioxidant capacity. The addition of fermented soursop leaf extract to drinking water caused the digestibility of dry matter, protein and changes in GE to DE to be higher (P>0.05) compared to the control treatment. The addition of fermented soursop leaf extract to drinking water had a significant effect (P<0.05) on carcass weight, and abdominal lipid components but had no significant effect (P>0.05) on carcass percentage and carcass physical composition. It can be concluded that the addition of water extract of soursop leaves (Annona muricata) fermented through drinking water in joper chickens at a level of 2% produces the highest joper chicken carcasses.
