The role of Clove (Cv) and Tulsi (Ts) supplementation on broiler growth performance and gut health as an alternative to antibiotic growth promoters has already been established. Therefore, the objectives of this study were to investigate the role of Cv and Ts on the serum biochemical profile and meat quality traits in broilers. A total of sixty (60) one-day-old commercial broiler chicks were randomly allotted into four homogenous groups (15 birds per group). They were then fed Cv powder and Ts extract from day (d) 8 to d 28 with drinking water i.e. zero level of Cv or Ts (T0), 0.5% Cv + 2% Ts (T1), 1.0% Cv + 3% Ts (T2), 1.5% Cv + 4% Ts (T3). Blood and meat samples were collected on d 14, 21, and 28 to analyze the serum-biochemical profile and meat quality. Supplementation of Cv and Ts improved serum-biochemical profile by reducing total cholesterol and low-density lipoprotein levels in broilers. However, they did not affect the serum protein levels while the 0.5-1% Cv and 2-3% Ts supplemented groups had higher glucose levels on d 21. Production of breast and thigh meat increased with increased size, and density of myofibers while fed 0.5-1% Cv and 2-3% Ts. On the contrary, 1.5% Cv powder and 4% Ts extract supplementation improved thigh meat color, breast and thigh meat pH as well as the water-holding capacity. The current study findings suggest that Cv and Ts can be used in combination to improve broiler health, production, and meat quality.
