Abstract

The objective of this study was to evaluate the physicochemical quality of whole Jack Beans mill and measure the Metabolic Energy (ME) and protein digestibility in broiler chickens by adding NSP and protease enzymes. The study used 20 five-week-old Cobb strain broiler chickens and followed a completely randomized design (CRD) with four treatments and four replicates. The treatments included P0 = Jack bean mill, P1 = P0 + Protease Enzyme, P2 = P0 + NSP Enzyme, and P3 = P0 + Protease Enzyme + NSP Enzyme. The results showed that adding NSP and protease enzymes to the feed increased the biological value, including metabolic energy and protein digestibility. The measurements of bulk density, tapped density, and metabolic energy in P1, P2, and P3 treatments were significantly (p<0.05) higher than in the P0 treatment. Based on the results, the study concludes that incorporating NSP and protease enzymes can enhance the nutritional value of jack beans for broiler chickens
