The invention relates to a feeding apparatus (100) used for feeding animals, such as cattle, in an animal shelter (50). The apparatus is arranged in connection with a feeding aperture (110) in the wall of the animal shelter, and it includes an air-permeating first wall (104) and an air-restricting second wall (106) together with a trough (102) for the dispensed feed. The first and second wall can be moved in front of the feeding aperture, in which case the feeding aperture is closed, and away from the feeding aperture, in which case the feeding aperture is open. A feed cover (108) has been placed onto the lower edge of the first wall in such a way that it covers part of the feed in the trough. Preferably the feed cover is a flexible structure made out of rubber, the free edge of which is equipped with an edge reinforcement (116). The first wall is fastened from its upper edge to the upper edge of the feeding aperture with hinges (112). The second wall is a sheet-like structure, which is thermally insulated and at least partially transparent, and it is fastened onto a support bar (120), which rotates around its longitudinal axis, the support bar being positioned into the upper edge of the feeding aperture. The second wall can also be a pull curtain fastened onto the first wall. A refrigeration system can be arranged in connection with the trough for preventing the feed in the trough from warming up.
