Hematological and serum biochemical indicators indicate chicken health, immunology, and metabolism. This study examined Noiler chickens' physiological and metabolic reactions to diets with different amounts of processed sweet potato peel meal (SPPM) instead of maize. A completely randomized design allocated 96 two-week-old Noiler chicks to four treatment groups with three repetitions per treatment and eight birds per replication. In four experimental diets, SPPM replaced maize at 0% (D1, control), 25% (D2), 50% (D3), and 75% (D4). After the eight-week feeding research, one avian subject per replication gave blood for hematological and serum biochemical analysis. Hematological measures included packed cell volume, hemoglobin concentration, red and white blood cell counts, mean corpuscular volume, hemoglobin, and concentration. Total protein, albumin, globulin, cholesterol, urea, creatinine, alanine, aspartate, and alkaline phosphatases were measured in serum. SPPM did not significantly affect (P > 0.05) most hematological measures, with all levels within healthy chicken reference ranges. The white blood cell count and mean corpuscular hemoglobin significantly changed (P < 0.05) between treatments. Serum biochemical analysis revealed substantial alterations (P < 0.05) in albumin, aspartate, and alanine transaminases, but no significant changes in total protein, globulin, alkaline phosphatase, urea, creatinine, or cholesterol. All parameters were within physiological limits, with no organ or metabolic issues. It was found that Noiler chicken diets may contain up to 75% processed sweet potato peel meal without adverse physiological or metabolic effects.
