Studies estimate that 10-15% of the feed used in grower-finishing units is never consumed by the pig but rather spilt onto the floor or lost in the manure. An idea has surfaced where adlib fed pigs are encouraged to visit the feeder less often during the day. This results in fewer meals with longer duration and intake. Feeders do tend to be visited far more frequently than is strictly necessary. Feeder design should be studied. A feeder would be loss-limiting if it provided the animal with enough room to lift its head and chew without drawing. Feeders should also have a through-view feature so the animal can see its penmates and be less threatened. Feed is also lost directly when the pig paws or roots it out. Pellets are better than meal and the adjustment of the feeder’s flow rate is vital. An important role will remain for managers in ensuring their feeders are positioned, adjusted and controlled correctly.
