Summary. Use of detailed norms for feeding geese with the introduction of fats into the feeding diet is necessary to increase feed conversion and to obtain better products. The presented article shows the results of studying of the effect of complete compound feed with different levels of crude fat on the chemical and fatty acid composition, organoleptic properties of the muscle tissue of young geese, as well as the biochemical composition of their blood serum depending on the level of crude fat and linoleic acid in complete compound feed. It was determined that the introduction of 2% of sunflower oil into the diets of geese in the starting and finishing complete compound feed did not reveal statistically significant differences in the concentration of protein and fat in the muscle tissue of young geese with an increase in the level of crude fat by 1.9-2.0% and linoleic acid by 43-47%, compared with the control (4.9-5.5% of crude fat). However, a tendency of an increase in the content of monounsaturated fatty acids in the muscle tissue, primarily palmitic acid, as well as an improvement in the organoleptic properties of meat was revealed in the experimental poultry. The developed complete compound feed did not adversely affect homeostasis in the body of young geese up to 60 days of age.
Keywords: geese, young geese, complete feed, crude fat, muscle tissue, unsaturated fatty acids, linoleic acid, tasting assessment, metabolism, blood, blood biochemical parameters.
