A total of 1500 day old broiler chicks were grouped into five treatments; each treatment group further consisted of six replicates. Group A was given a control diet having antibiotics. Group B and C were offered essential oil blend at the proportion of 0.1 g/kg and organic acid at the dose rate of 1g/kg. Group D was given both essential oil 0.1 g/kg and organic acid 1g/kg in combination. Group E was offered only a basal diet without antibiotics and considered as a negative control. The trial lasted for 35 days. Results indicated that the body weight gain and feed conversion ratio (FCR) exhibited significant improvement but insignificant in the case of feed consumption. Bodyweight and FCR were better in group B, followed by C. Carcass characteristics like eviscerated weight and giblet weight were also improved in group B while dressed weight showed insignificant results. Total cholesterol and high-density lipoproteins (HDL) were unaffected by the treatments; however, increased blood glucose levels and decreased low-density lipoproteins (LDL) concentration were significantly noticed. Treatment groups have no effect on antibody titer against ND at the end of the trial. In gut morphology, significantly higher villus height was observed in group C, but villus width and crypt depth remained unaffected. In conclusion, essential oil and organic acids have improved performance, carcass parameters, serum biochemistry, gut health, and decreased bacterial count.(AU)
