The study of the composition and process for additional feeding and deworming of hares is an important, fundamental and, especially, applicative issue, because some species serve as definitive hosts in the development cycle and as parasitic vectors, being dangerous for both domestic animals and humans. Parasitosis are the most common diseases in wildlife of the hunting fauna, which results with substantial economic losses. The invention relates to the protection of hunting fauna, namely to a composition and a process for additional feeding and deworming of hares. The composition, according to the invention, comprises, in %: oats 30.0-50.0, wheat 4.0-7.0, barley 2.0-4.0, corn 2.0-4.0, sunflower groats 2.0-4.0, soybean groats 2.0-4.0, bentonite 20.0-30.0, molasses 1.0-2.0, dextrin 2.0-3.0, premix containing vitamins, oligoelements, minerals, coccidiostatic and antioxidant 1.0-2.0, and a preparation containing 20% albendazole 1.0-2.0. The process, according to the invention, provides for the administration to hares of said composition, in a dose of 75 g/hare, in winter, twice with an interval of 14 days, in the form of briquettes, placed at a height of 25-40 cm from the soil.
