Pen gestation appears to be the future of sow housing, and helping pork producers pick an option that suits their operation is the goal of Innovative Swine Solutions (ISS), says Laura Greiner, director of research and swine nutrition. To help producers define their choices on sow housing, ISS has begun studies of two very different pen arrangements, a drop feed system and electronic sow feeder. It is concluded that so far, one system isn’t better than the other for sow housing. There is no right or wrong answer. Both farms do very well. It comes down to established protocol that we understand and whether we know how to feed these animals.
