Abstract: A poultry-farming battery cage farming has at least two horizontal cage rows, formed with cage enclosures, arranged alongside one another, that are formed with double cages made up of cages that back on to one another. Under each row extends a droppings receptacle, over which air-fanning flaps are longitudinally spaced apart, each air-fanning flap having an upper force-transmission part and a lower fan part mounted on a transverse axis arranged near an upper air-fanning-flap end. The two cages of each double cage have cage bottoms extending away from one another transversely and are separated from one another by a common vertical longitudinal rear wall arranged at a vertical spacing above the upper air-flap end. The fan part of the air-fanning flap is arranged under the associated cage bottoms. The air-fanning-flap end is arranged in a double-cage area, from which the cage bottoms extend away from one another transversely.

Abstract: A calf warming device having a housing that encloses a newborn calf therein. A base member of the housing comprises a heated surface while sidewalls contain scent openings. Along with the scent openings the housing has at least a transparent portion such that when the calf is warming a mother cow can not only see her calf but additionally smell her calf to ensure the mother cow does not reject the baby calf after the warming process.
