The digital intelligent feeding management system for sow is able to manage thousands of sows. Each sow is provided with electronic ear tag which can record their age, oestrous cycle, gestation length and immune condition etc. the management system will significantly improve automation and delicacy management in pig farms and thus obtain benefit maximization.

1. Hand fed is not required. In individual feeding, each sow will automatically open the mechanical door to eat food, and then the system will identify ear tag and supply feedstuff according to health condition of each sow. The eating ways are flexible. The health condition of sows will be controlled and the waste of feedstuff will be prevented.

2. Artificial check is not required. The system will continuous check oestrus condition of sow for 24 hours to ensure accurate check and high efficiency of breeding.

3. Automatic isolation: the system will isolate pigs which need to be isolated to the isolation area such as estrus sows, expectant sows, ill sows and sows requiring vaccination. Then marks will be sprayed for workers in pig farms to carry out corresponding treatment. This significantly reduces labor force and improves efficiency of labor.

4. The equipment is connected to computer via management module. The management personnel of pig farms will obtain the first-hand information of pigs through "Internet" even without their presence.
   
   

The sow feeding station is based on individual feedstuff supply. In addition, the feedstuff supply efficiency is high and the effect is better. Management of feedstuff supply may have other advantages. The proportion of feedstuff cost in allocated cost of sows is as high as 35%. In addition, health of sows will be controlled by feedstuff. Management on feeding process may directly increase achievement of enterprise.
