Eight goats aged 6%u20138 months and weighing 10%u201315 kg were used in a change-over design, receiving four dietary treatments: DMF0 (70% Kume grass hay + 30% concentrate), DMF1 (52.5% Kume grass hay + 17.5% hydroponic maize hay fodder + 30% concentrate), DMF2 (35% Kume grass hay + 35% hydroponic maize hay fodder + 30% concentrate), and DMF3 (17.5% Kume grass hay + 52.5% hydroponic maize hay fodder + 30% concentrate). Blood parameters measured included leukocytes, erythrocytes, hemoglobin, and hematocrit (PCV), and data were analyzed using ANOVA with SPSS version 25. The results showed that substituting Kume grass hay with hydroponic maize hay fodder had no significant effect (P > 0.05) on all measured blood parameters. Mean values ranged from 9.612 to 19.975 %u00d710%u00b3/%u03bcL for leukocytes, 12.920 to 18.773 %u00d710%u2076/%u03bcL for erythrocytes, 6.875 to 10.125 g/dL for hemoglobin, and 19.925% to 30.200% for hematocrit. It can be concluded that hydroponic maize hay fodder is a viable alternative forage that does not negatively impact the blood profile of Kacang goats, thereby supporting metabolic balance and overall animal health.Keywords: Kacang goats, hydroponic maize hay, Kume grass hay, blood profile, forage substitution, hematological parameters
