| Popis: | Effects of the probiotic ‘Protexin', basil essential oil and the antibiotic growth promoter ‘Avilamycin' were studied on the ileum microbial flora of broilers when these substances are used as broiler feed additives. A total of six hundred Arian broilers were divided into 6 treatment groups, with 4 replicates of 25 birds. Treatments have been performed with a plant essential oil at 3 levels (200, 400 and 600 ppm), the probiotic ‘Protexin' (150 ppm), the antibiotic ‘Avilamycin' (150 ppm) and a control group with no additives. Birds in different treatments received the same diets during the experimental period. The results showed that the probiotic treatment significantly decreased the total bacteria counts (P0.05). The lowest and highest lactic acid bacteria in ileum were obtained in the control group and in birds receiving 400 ppm basil essential oil, respectively. Moreover, addition of 600 ppm of basil essential oil into diet decreased the number of E. coli colonies as compared to other treatments (P< 0.05). It could be speculated that the basil essential oil and ‘Protexin' could replace the antibiotics, which have been banned to use as growth promoter in animal feeds. |
