By mixing feed phase rations for grow-finishing pigs, Canadian researchers have been able to reduce both feeding costs as well as the emission of harmful compounds in the environment.
This is stated on the website of Pig Progress. Canadian and French researchers based this new feeding strategy on a traditional feeding system, which is based on phases, combined with an advanced feeding system, using blend feeding. The scientists stated that their plan stemmed from the notion that feed costs are the most important part of the production cost, so any reduction is a bonus.
The scientists concluded that, compared to the traditional feeding system, this combination of diets led to a feed cost reduction of 5.2%. In addition, they found that nitrogen (N) and phosphorus (P) excretion also decreased, by 17.8% and 2.2%, respectively.
