The effect of essential oil encapsulated oregano on microbial population and morphology of intestinal tract in broiler chickens

The aim of this experiment was to assess the effects of encapsulated oregano oil on microbial population, morphology, length and weight of different parts of digestive tract of Aryan broiler chicks. A total of 625 Arian broiler chicks were used in a completely randomized trail with 5 treatments and 5 replicates at the age of 1 to 42 days. Treatments were including: 1- basal diet (negative control), 2- basal dietꚺᮊ譢 (0.1 g Protexin/kg), 3- basal diet橻扮⨭ (0.15g Avilamycin/kg), 4- basal dietꊷꁪ oil (0.2 g/kg) and 5- basal diet穷᪦쮥櫗 oregano oil (1 g/kg). The results showed that broiler performance at the end of 42 days were not affected by treatments (p0.05). Finally, according to result of intestinal microbial count, it seems that encapsulated oregano essential oil can improve the intestine microbial population and bird's health.
