Antibiotics widely used in poultry farms can have a harmful effect on meat consumers through chemical residues. Thus, it is important for the safety of customers to find a natural alternative. The purpose of this study was to evaluate the effectiveness of adding a poly-enzyme preparation “Universal”, containing amylosubtilin (1300 U/g), protosubtilin (67 U/g) and celloviridine (2000 U/g), on the productivity of broiler ducklings of the Cherry Valley breed. The results of research have shown that the addition of the “Universal” drug in the diet helped increase the meat productivity of broiler ducks. The use of the “Universal” drug contributed to the better development of internal organs (heart, liver and stomach) in broiler ducks. The improvement in duck weight and meat yield may be attributed to the fact that the feed protein is best consumed under the influence of protosubtilin, one of the “Universal.” It is understood that protosubtilin supplies digestible peptides and amino acids with hydrolysis of plant proteins from grain raw materials, enhances the gastrointestinal tract’s enzymatic history, compensates for the loss of depleted digestive enzymes and at the early stages of animal growth. Thus, the results of the experiment showed that the use of the drug “Universal” in the cultivation of broiler ducks of the cherry valley breed increases the pre-slaughter and slaughter weight, meat yield and reduces feed conversion, which is economically profitable. Therefore, it is recommended to use the drug “universal” as part of ration for broiler ducklings.
