Abstract

The effect of plant based essential oil with or without probiotics via drinking water was determined on the performance parameters of broilers. Two hundred forty (240) day-old Cobb broiler of mixed sex were divided into four treatments, each treatment was replicated six times having ten chicks per replicate. Data parameters were gathered at the end of booster, starter, and finisher phase and throughout the whole trial period. Antibiotic supplementation had the highest body weight gain, average daily gain and average feed consumed. Antibiotic treatment also had significant results in feed conversion ratio followed closely by control group, treatment 4 and treatment 3. Income Over Feed Chick and Medication Cost (IOFCMC) were highest in essential oil treatment followed by essential oil with probiotics and by antibiotic treatment. Antibiotic treatment may be used during the booster phase since it showed significant results during this period. Then, changing to essential oil with or without probiotics, since they have comparable effects, in order to prevent antibiotic resistance.
