<p>An automatic water supply system used for raising domestic animals such as cattles, horses, poultry and so on and especially for pigs. Instead of a water flow control means such as a valve, float or the like provided in a self supply water trough, a flow control container is used which is communicated through a water supply pipe to a common water storage tank, placed at an elevated position inaccessible to a pig or the other animals and includes a float, a valve and a siphon which may ensure the automatic and positive supply of water into the trough as the water level in the trough is lowered by an animal drinking therefrom. Therefore the unnecessary supply of water caused by the undesired engagement of the mouth of an animal with the water flow control means in the trough mischieviously, and/or the stopping up of the drain with remaining food particles may be completely eliminated.</p> |
