The development of a feeding diet is necessary for the development of the poultry industry. In the West Kazakhstan region, we studied the technology of feeding waterfowl and the chemical composition of feed and feed additives. The analysis of the chemical composition and nutritional value of the feed was carried out, based on which feed mixture formulae for ducks of different sex and age groups bred at the Zhangir Khan Agricultural and Technical University were compiled. The experiment included one control and three experimental groups with different diets. Each group included 50 heads, and the birds were selected by the live weight analog group method. The study showed that when a composite mineral feed additive in a dosage of 4% was added to the ducklings' diet, the ducklings gained more live weight. The study concluded that the incorporation of 4% composite mineral feed additive significantly enhanced the growth rates of young ducklings compared to the control group. This suggests that such feed formulations could improve productivity and offer a cost-effective strategy for poultry development in the region
