This article evaluates the economic efficiency of the combined supplementation of broiler chicken diets with chitosan and whey powder. The experiment was conducted on 120 one-day-old Cobb-500 broilers, divided into four groups (control, chitosan, whey, and combination) for a period of 42 days. Throughout the experiment, zootechnical indicators such as live weight, feed consumption, feed conversion ratio, carcass yield, and livability were monitored, alongside calculations of production costs and revenue. The results indicated that supplementation, both individually and especially in combination (2% chitosan + 5% whey), accelerated chicken growth, improved feed conversion efficiency by 8.9%, and increased livability. Economic calculations revealed that in the combination group, the feed cost per kg of weight gain decreased by 15.2%, while the cost per tonne of live weight was reduced by 14.3%. Consequently, the net profit per tonne increased by 66.7%, and the profitability margin rose to 25.0%. It was concluded that the combination of chitosan and whey powder not only enhances the biological efficiency of broiler meat production but also delivers high economic returns, making it a viable strategy for the industry.
