The invention discloses an intelligent drinking water system for animal breeding. The intelligent drinking water system comprises a boiling tank, a temperature regulating tank and a drinking water tank, the boiling tank is provided with a water inlet pipe, the bottom of the boiling tank is communicated with the temperature adjusting tank, and the bottom of the temperature adjusting tank is communicated with the drinking water tank; an electric heating device and a scaling net are arranged in the boiling tank, and a first valve is arranged between the boiling tank and the temperature adjustingtank; a first temperature sensor, a first water temperature adjusting device and a first water level sensor are arranged in the temperature adjusting tank, a second valve is arranged between the temperature adjusting tank and the drinking water tank, and a second temperature sensor, a second water temperature adjusting device and a second water level sensor are arranged in the drinking water tank;a PLC and an infrared body temperature sensor are also arranged, the infrared body temperature sensor is used for detecting the real-time body temperature of animals. According to the system, the temperature of drinking water can be adjusted according to the real-time body temperature of the animals, so that the normal body temperature of the animals is helped to be maintained, diarrhea caused bynon-scientific water drinking of animals is avoided, and the healthy growth of the animals is guaranteed.
