Electronic sow feeders systems typically provide one (or very few) feed lines to accommodate a large number of sows(typically 40 to 60 sows per channel). Sows must be fed one by one from the same station.
An electronically controlled feeder distributes a certain amount of feed, after which it is placed in the feed pan for a limited period. For more information about electronic sow feeders you can visit https://www.feedworks.com.au/product/equipment-feeding-systems/nedap-electronic-sow-feeders/.

The front door remains locked all over the rest of the feed and for a few minutes to ensure that other sows cannot enter. Machines usually work every day with a new feed distribution available every 24 hours.
Because the farmer is not available while every pig is feeding, the system must provide feedback on any sows that fail to eat their allotment each day.
This feedback takes the form of a care checklist that is easily accessible to the farmer at the end of each 24-hour cycle and can also be used to identify animals that may need additional care.
The ESF is a group house system that allows real control over individual feed intake. As soon as the pigs enter the machine for the first time, supervisors feed them one feed into the computer system.
This can determine the amount of feed the pigs receive daily and for gains as gestation progresses. The system automatically adjusts the diet and keeps your sow in optimal physical condition.
