The authors developed a multi-criteria model that considers minimum nitrogen and phosphorus excretion and minimum costs. The models were based off real world diets and costs from Quebec and France and then compared. After making the comparisons the results showed that it is possible to limit the amount of harmful nutrients excreted while still keeping costs down. This information has value to producers, mill operators and also policy makers who can set limitations or incentives to help protect the environment from soil saturation.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Traditionally a pig&#8217;s diets\u00a0is created based on two pieces of criteria, growth and cost.
