Effect of Nutri gold feed supplement in ration on carcass characteristics of Balitbangtan native chickens

Balitbangtan native chickens have the potential as a meat source however, their slow growth affects weight and carcass characteristics. This study aimed to determine the effect of administering Nutrigold Feed Supplement in commercial rations on the carcass characteristics of  balitbangtan native chickens. The study was conducted for eight weeks using a completely randomized design (CRD) with four treatments and five replications, with each treatment unit consisting of five chickens. The treatments were as follows: T0 = 0% Nutrigold Feed Supplement (control), T1 = 1%, T2 = 2%, and T3 = 3% Nutrigold Feed Supplement in commercial feed. The results showed that the administration of 2–3% Nutrigold Feed Supplement significantly (P<0.05) increased slaughter weight compared to T0 and T1 treatments. The supplementation of 1–3% Nutrigold Feed Supplement in T1, T2, and T3 treatments significantly (P<0.05) increased carcass weight and reduced the percentage of subcutaneous fat, including skin, compared to T0. The administration of 3% Nutrigold Feed Supplement in T3 significantly (P<0.05) increased carcass percentage and meat percentage compared to T0, while the bone percentage did not differ significantly (P>0.05) among the four treatments. The study concluded that the inclusion of 2–3% Nutrigold Feed Supplement in commercial feed could increase slaughter weight, while 1–3% Nutrigold Feed Supplement improved carcass weight and reduced subcutaneous fat, including skin. The addition of 3% Nutrigold Feed Supplement in commercial feed increased the carcass and meat percentage compared to the control treatment in 8-week-old balitbangtan native chickens.
