ABSTRACT:
The present invention relates to an animal box for animal breeding. The problem underlying the invention is the poor hygienic conditions associated with conventional animal breeding, in particular pig breeding, with the resulting considerable risk of infection, administration of antibiotics, poor working environment and low animal growth. Another problem today is the difficulty in moving the dung to grounds which are not already overfertilized.
The above problem is mainly due to the fact that the dung cannot be removed and utilized in a satisfactory manner and that the animals cannot stay in the same box from birth until they are a suitable size for disposal, but have to be moved between different boxes mixing with different litters with the resulting risks of infection.
In SU-A 1 230 559 an animal box is described with a conveyor belt carrying the animals. During the cleaning the belt is moved in one direction out from the box while the animals are removed from the box. Since the belt after cleaning and strawing has been brought back in the opposite direction the animals are returned to the box. However, this box, which from a superficial point of view reminds of the present invention, does not solve the above stated problem. Even if it may be considered to facilitate the cleaning a little it requires that the box is removed at each cleaning.
These and related problems are solved by the animal box of the invention having been given the features stated in the characterizing portion of claim

. Further improvements and modifications are stated in the dependent claims.
