Abstract: The present invention provides a feeder for poultry including a receptacle (20) having two chutes (21,22) of which one is made to be located inside the other chute, said chutes being able to assume different positions relative to one another, between one position where said first chute (21) is inside the second chute (22), the receptacle presenting its lowest capacity for feed presentation, and another position where said chutes (21,22) only overlap in an area of small size, the receptacle thus presenting its highest capacity for feed presentation.

Abstract: The present invention is a watering system for small animals and fowl which provides for automatic cleaning of the internal surfaces of the conduits of the system. In such a watering system, residue from the water supply or nutrients in the form of vitamins, medicines, or other water additives may accumulate on the inner surfaces of the watering system conduits. This accumulation of sediment and nitrients provides a suitable environment for the growth of bacteria and other biological contaminants which may infect livestock. The invention involves connecting the conduits of a poultry house in an arrangement so that upon activation of a high pressure water supply, a high pressure fluid circuit is formed within the conduits to flush the inner surfaces of the conduits. The system may be operated automatically because mechanical switching of valves on the conduits is not required to provide the high pressure fluid flow which scrapes away the biofilm on the inner surfaces of the conduit.
