It was hypothesized that dietary supplementation of chitosan oligosaccharide (COS) and valine will ameliorate the biochemical profile of Ross 708 broilers between days 21 and 42 after hatching. To investigate this hypothesis, 480 male broilers were randomly placed in eight treatment groups with two dietary levels of COS (C1: 100 mg/kg and C2: 150 mg/kg) and four dietary levels of valine (V1: 0.57%, V2: 0.72%, V3: 0.87% and V4: 1.02 %) with three replicates having 20 birds in each. The blood samples for serological and haematological profiles were collected and analysed at the age of 42 days to evaluate the effects of supplementation. Serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) decreased with the lowest response values when birds were supplemented at V3 at both C1 and C2. Serum triglycerides (TG) and cholesterol (CHO) levels reduced linearly with increasing supplemental levels of valine at both regimen of COS with the lowest values of 61.07 ± 1.12 and 125.33 ± 1.40 for diet supplemented at V4 and C2, respectively. Serum uric acid (UA) and total proteins (TP) increased linearly with increasing supplemented levels of valine at both C1 and C2. There was a linear increase in total leucocyte count (TLC) and red blood cell (RBC) count for increasing supplemental levels of valine at both C1 and C2. An interactive effect of COS and valine was observed for the changes in ALT, albumin (ALB), TLC and haemoglobin (Hb). In conclusion, COS and valine supplementation significantly affected the liver, renal, lipid and haematological profiles of broilers.
