N&H TOPLINE: Take steps to maintain mineral digestibility in high-zinc diets

When feeding high levels of zinc in postweaning pig diets, increasing calcium and phosphorus levels or including phytase can counteract reduced mineral digestibility.

University of Illinois researchers have shown that a common strategy for reducing postweaning diarrhea in pigs may have negative effects on calcium and phosphorus digestibility, but management practices may counteract those effects.

The biological requirement for zinc in growing pigs is approximately 50 mg/kg of bodyweight. However, pharmacological levels of zinc — 2,000-3,000 mg/kg — are sometimes included in diets fed to pigs after weaning to help prevent postweaning dia
