Abstract

This study was conducted to describe the feature of jejunal mucosa of broiler chickens given essential oils. A total of 240 day-old Cobb broiler chicks of mixed sexes were used in the study. The chicks were randomly distributed into four treatment groups: treatment 1 ? basal feed only, treatment 2 ? basal feed plus antibiotic growth promoters, treatment 3 ? basal feed plus essential oils feed supplement and treatment 4 ? basal feed plus essential oils supplement and probiotics. Each treatment was replicated six times with ten chicks per replicate. Upon harvest at day 35 of age, the jejunal segments were obtained and subjected to jejunal scoring system and observation of pathologic lesions. The study found no significant statistical differences among the means across all treatments for jejunal scores and lesion. It can be concluded that the use of essential oil supplementation and probiotics given via the drinking water does not affect the macroscopic features of jejunal mucosa.
