This study discovers the possible synergistic effect of probiotics, prebiotics, butyrate and essential oil (All-Pro feed) that can be beneficial for improving the growth performance of broiler chickens and coccidian control. Materials and Methods: A total of 480 one-day-old Ross 308 broiler chicks (as hatched) were subjected to a 5 weeks dietary experiment. The chicks were randomly divided into 2 experimental groups, group 1 fed basal diets only (T₁), group 2 fed basal diets supplemented with 750 g t^–1 (All-Pro feed) T₂. Each treatment comprised 4 replicates (60 chicks per replicate). It includes parameters for production performance as body weight gain feed consumed and feed conversion ratio. Immunological, histomorphology and coccidian study. Statistical analysis was conducted using the student’s t-test. Results: There was a significant increase in Body Weight Gain (BWG) in the group treated with All-Pro feed compared with the control group in the hall period of the experiment. There was a significant improvement in Feed Conversion Ratio (FCR) between the control and treated group except for the 3rd week. Adding All-Pro feed increased villus height and width linearly, increased humoral immunity and reduced coccidian oocyte shedding in faeces of chickens at different ages. Conclusion: From the above study can prove the synergistic action of herbal extract with synbiotic to control coccidiosis in chickens in addition to its role as growth promoters.]]> https://scialert.net/abstract/?doi=crpsaj.2021.1.10 10 June, 2026
