Water-saving waterer for livestock breeding

The invention discloses a water-saving waterer for livestock breeding, which comprises a bottom plate. Drainage grooves are opened equidistantly at an end face of the bottom of a water storage tank. Awater blocking plate is slidably connected inside each drainage groove. Each water blocking plate is provided with a drainage hole in the middle. According to the invention, the water-saving watererfor livestock breeding is scientific and reasonable in structure, and safe and convenient in use. An animal steps on a pedal to drive a connecting rod, sliding columns and the corresponding water blocking plate to move downward, so that the water in the water storage tank flows slowly into a basin through the drainage hole for the animal to drink, the water loss caused by the direct exposure of the water to the air is reduced, the spillage of the water in the basin is also reduced, and the function of saving water is achieved. In addition, return springs are set to ensure the pedal returns tothe original position after
