<![CDATA[The use of feed additives has the potential to increase nutrient efficiency. This study aims to determine the effect of using the bromelain enzyme by-product (BEBP) as a feed additive on the nutrient efficiency of Joper chickens. This study used a completely randomized design with 3 treatments, each with 6 replications and 4 chickens per replication. This research was conducted over 56 days. The treatments given were: T0: basal ration without BEBM; T1: basal ration + 1% BEBM; T2: basal ration + 2% BEBM. The results showed that BEBM supplementation up to 2% had no significant effect (P>0.05) on feed intake (175.09 ± 14.61; 185.83 ± 14.61; 150.75 ± 14.61 g), average daily gain (64.94 ± 6.88; 65.24 ± 6.88; 57.79 ± 6.88 g), protein efficiency ratio (1.77 ± 0.14; 1.66 ± 0.14; 1.83 ± 0.14), and energy efficiency ratio (11.98 ± 0.93; 11.11 ± 0.93; 12.48 ± 0.93) for T0, T1, and T2, respectively. The results showed that the provision of BEBM up to 2% did not significantly affect the efficiency of joper chicke. It can be concluded that the use of BEBM has not increased the nutrient efficiency of Joper chickens.]]>
