As part of the Sam Higginbottom University of Agriculture, Technology and Sciences in Prayagraj, this experiment was carried out at the Small Animal Lab which is part of the research unit. We investigated the “economic cost of including probiotics in the feed of caged broilers”. We used a total of 96 day-old chicks and were randomly assigned four groups of 24 chicks (T0, T1, T2, and T3) and eight replicates each, these groups. T0 control group was fed the (BD), T1 was fed Bacillus coagulans at 40 ppm in BD, T2 was fed B. subtilis at 50 ppm in BD, and T3 was fed B. licheniformis and B. coagulans 20 ppm in BD. After a 35-days trial period, an analysis of the economic effects of the probiotics supplementation was calculated. The results revealed a decrease in FCR as birds achieved more weight, leading to increased body weight and resulting in a higher price per kg. Adding probiotics to the feed doesn’t increase the variable cost than the control group. It was found that the maximum profit was obtained in T3 (Rs. 5771.32), T0 (Rs. 5297.3), and T2 (Rs. 5074.92), whereas the T1 group had the least revenue. Mixing probiotics in poultry feed increases profit without much affecting the production cost.
