Impact of humic drug on meat productivity and development of internal organs in ducklings

Relevance. Modern poultry farming is an intensively developing sub-sector of animal husbandry, making a great contribution to the food security of the state. Feed additives, primarily of natural origin, are an integral part of the poultry diet. Humic preparations have great prospects for use in animal husbandry.Methods. To study the effectiveness of using Guvitan-C in feeding ducks, three groups of day-old ducklings were formed. The bird of the control group received the main diet. Ducklings of the I experimental group were additionally fed a humic feed additive in the amount of 100.0 ml/kg of feed, poultry of the II experimental group were fed at a dose of 150 ml for 56 days. At the end of cultivation, ducks were slaughtered, after which meat productivity and the development of internal organs were evaluated.Results. The inclusion of Guvitan-C in the diet of ducklings contributed to an increase in the meat productivity of poultry of the experimental groups. The mass of the gutted carcass increased by 11.94–15.11% and 11.34–15.37%, respectively, the mass of muscle tissue increased by 13.35–17.38%. In addition, it turns out more skin with subcutaneous fat and internal fat. Ducklings had better development of internal organs and intestines. The number of carcasses of the first grade was 93.48–94.63% with 86.82% in the control.
