Abstract
For an extended period, the poultry industry has
employed antibiotics as feed additives to enhance the growth of birds.
Nevertheless, the utilization of antibiotics raises significant concerns
regarding the development of antimicrobial resistance. Consequently, it is
essential to identify effective and safe alternatives for feed additives, such
as essential oils. The study was meticulously designed to assess the effects of
essential oil blends as feed additives in broilers. A total of 600 day-old
broiler chicks (n=600) were randomly assigned to five treatment groups, each
comprising three replicates with 40 birds per replicate. Treatments were the
following: Group A (basal diet + antibiotics) positive control, Group B (basal
diet only) negative control, Groups C, D, and E consisted of essential oil blend
at the dose rate of 0.12mL/kg, 0.25mL/kg, and 0.50mL/kg of feed, respectively.
The duration of the trial was 35 days. The findings revealed significant
improvement in body weight and feed conversion ratio (FCR), while feed
consumption showed no notable changes. Body weight gain and FCR were
significantly better in group E. There was no significant improvement in carcass
characteristics like eviscerated, dressed, and giblet weights. Meat pH, meat
color, and antibody titer against ND were affected significantly (P<0.05) by
treatment group E. Villus length was significantly higher in group D, while
crypt depth and villus width remained unaltered. Total bacteria count was
noticed to be lower in treatment groups than in control groups. In conclusion,
essential oil supplementation has enhanced performance, gut health, meat
quality, immunity and decreased total bacterial count.
