Swine nutritionists at Kansas State University have updated their recommendations for feeding nursery pigs, based on recent research trials. The new guidelines include adding more amino acids and less fat to the pigs’ diets, says Mike Tokach, Kansas State swine specialist.
“The recommendations are based on a series of experiments in which we tested pigs’ response to various energy and amino acid levels in their diet,” adds Tokach.
Kansas State’s new feeding recommendations include:
Increasing lysine levels in nursery diets with increased use of L-Threonine and a methionine source.
Limiting added fat levels to a maximum of 3 percent in Phase 2 and 3 diets.
Making minor changes in Segregated Early Weaning and transition diets.
“We update these recommendations as often as we have trials that indicate a better way to feed pigs for improved profitability,” says Tokach.
The benefit of the new guidelines to producers and the pork industry isn’t necessarily in reducing feeding costs, he adds, they should remain about the same. Rather, the benefit may be found in increased revenue because the pigs’ final weight “should be about two pounds heavier than achieved with the lower lysine levels.”
