Currently, the poultry industry is growth and the by-products of poultry processing has also increased. The increase in the scale of production of chicken meat, the increase in the share of poultry farms makes the problem of the integrated use of waste from poultry farms urgent. Scientific research on testing feed feather meal produced by Terafix LtD was carried out in the Department of Animal Resources and Food Safety of the Technical University of Moldova. Broiler chickens COBB 500 served as the material for the study. Chickens of the control group received the main compound feed, and the experimental grou included different amounts of feather meal instead of fishmeal. It was found that the inclusion of feather meal in the compound feed at the level of 1.5% when feeding broiler chickens led to an increase in the live weight of average daily gains by 0.35% and a decrease in feed costs by 4.79%.
