Abstract

Essential oils (EOs) and organic acids (OAs) are promising feed additives with crucial roles in promoting animal health and performance. This study aimed to assess the combined effects of phytobiotics with organic acids (EOAs) in broiler diets for 39 days. Daily 300 male chicks were assigned to three groups, each containing 100 chicks with 5 replicates. The basal diet was supplemented with 0, 0.1, and 0.2% EOAs, respectively. EOAs supplementation did not significantly affect performance values. The villus height/crypt depth ratio in the jejunum and villus dimensions in the ileum showed improvement with EOAs. Dietary EOAs supplementation led to a reduction in the count of Enterobacteriaceae and an increase in Lactobacillus in the caecum. Serum IgA and IgG levels increased with EOAs. Ultimate load, yield load, and the levels of ash, calcium, phosphorus, zinc, and manganese in the tibia and femur were higher at high levels of EOAs than in the other groups. In conclusion, the study suggests that 0.1% EOAs usage in diets could be a viable option for enhancing intestinal health, immunity, and bone mineralization as an alternative growth promoter, especially in commercial broiler production.
