Rethinking sow nutrition: Sow feed needs to be higher in lysine and energy, new research shows

摘要

INFORMATION ABOUT feeding sows is woefully out of date, but a University of Alberta research team is attempting to change that. Lysine and energy requirements are likely the most incorrect items in a sow ration, says Ron Ball. "We are depositing morelean, less fat and that has changed the underlying basic metabolism of the pig. They are working a hell of a lot harder, growing faster," he says. "Sows in fewer days raise more pigs to greater weight. It takes a lot of energy to produce a kilo more of milk."
