This paper presents the calculation of complementary food needs for animal species, which live in the hunting fund no.20 Higeg. This calculation is absolutely necessary to be predetermined and properly distributed, so that in winter, the animals have required amount of food to survive, in order to develop and reproduce normally. Supplementary food is given only in winter, especially when snow prevents hunting to feed. Complementary food comes, as the name implies, to complement the very poor diet of the animals. The amount of complementary food is based on its quality of each species.
