Hematological blood profile of Kampung Chicken fed diets containing fermented coffee husk

Coffee husk is a potential alternative feed ingredient for poultry; however, its application is limited by its low protein content and high crude fiber levels. Fermentation is a promising strategy to improve the nutritional quality of such by-products. This study aimed to evaluate the effects of fermented coffee husk (FCH) on the hematological profile of grower-phase Kampung chickens. A Completely Randomized Design (CRD) was used, consisting of four treatments with four replications. The treatments were T0 (100% basal feed), T1 (90% basal feed + 10% unfermented coffee husk), T2 (90% basal feed + 10% FCH fermented with Saccharomyces cerevisiae), and T3 (90% basal feed + 10% FCH fermented with EM4) Hematological variables measured included erythrocyte count, leukocyte count, hemoglobin concentration, hematocrit, and platelet count. Although no significant differences were observed among treatments, the inclusion of FCH tended to improve hematological parameters compared with the control. Fermented treatments showed a positive trend in supporting physiological health and blood profile improvement. These findings indicate that FCH has potential as a sustainable local feed ingredient for Kampung chicken production.
