Heat stress is an environmental stressor limiting the performance and production of poultry birds. This study therefore, carried out to investigate optimum combination of aspirin (ASA) and salt (NaCl) that will combat heat stress in Marshall Breeder cock and synergistically improve serum biochemistry and suppress the expression of cytokines. Sixteen Marshall breeder cocks were used in this experiment. Four diets were formulated and labelled T1 (the control 0.25% NaCl and 0.00% ASA), T2 (0.50% NaCl and 0.025% ASA), T3 (0.75% NaCl and 0.050% ASA) and T4 (1.00% NaCl and 0.075% ASA). The cocks were randomly distributed into four treatment diets with four replicates in each treatment and fed for 16 weeks. Total protein (7.91 ± 1.11mg/dL), globulin (3.40 ± 1.12mgldL) and creatinine (451.69 ± 50.76mg/dL) were significantly (P<0.05) higher in the control diet while diet T4 had the highest percentage of albumin (4.90 ± 0.06mg/dL) and aspartate aminotransferase (67.70 ± 7.66mg/dL). T3 (178.5) and T4 (230) had the lowest expression of tumour necrosis factor alpha gene in the liver and heart respectively while the control diet T1 (244.5) and T4 (155) had lowest expression of interleukin-1gene in the liver and heart respectively. In conclusion, 0.750% NaCl worked synergistically with 0.050% ASA to suppress the expression of tumour necrosis factor alpha gene in the liver while 1.00% NaCl with 0.0750% ASA could be used to reduce urea concentration in the blood and also suppress the expression of tumour necrosis factor alpha gene and interleukin-1 gene in the heart of breeder cocks.
