Abstract

A 28-day feeding trial was conducted to evaluate the effects of varying levels of oregano powder in broiler starter diets. About 240eight-day-old chicks were used in the study. Four treatments were randomly allotted to 24 cages following a completely randomized design (CRD). Broilers were fed commercial feeds with0%, 1.5%, 2.0% and 2.5% oregano powder from 8th to 28th day of age. No significant differences were observed in the feed consumption, dressing percentage and livability of the birds. Significant differences (p<0.05) were observed in the body weight gain of the birds, wherein birds fed diets with 1.5% oregano powder had the highest body weight gain while birds fed control diets had the lowest bodyweight gain. Feed efficiency of the broilers had significant differences (p<0.05), in which broilers fed diets with oregano powder had better feed efficiency. Birds fed diets with oregano powder had better feed cost efficiency value than birds fed control diets. The income over feed and chick costs (IOFCC) was improved with the supplementation of oregano powder. This study showed that oregano powder in broiler diets improved the performance of broiler chickens and 1.5% level of oregano powder in the diet is the optimum inclusion level.
