Sustainability through precision swine feeding

In pork production, environmental impact is mainly centred on the excretion of excess nitrogen and phosphorus from feed. Through precision feeding, pigs can retain significantly more of the nitrogen found in the protein in their feed, and therefore excrete much less than pigs reared in conventional group phase feeding programmes. Several years ago, a team of scientists from Brazil and Canada examined how much general environmental impact might be decreased in Brazilian swine production by switc
