Potassium is one of the mineral nutrients that has been considered to be present in adequate amounts in swine diets formulated with commonly used feed ingredients. However, nutrient contents of feed ingredients have been shown to change with intensive cropping practices and also with different feed processing procedures. Recent research has indicated that potassium may improve the utilization of lysine, particularly in diets containing lysine below recommended levels.
This study was conducted to evaluate the performance of growing-finishing pigs fed different levels of supplemental dietary potassium and to evaluate the effect of previous dietary lysine treatment on subsequent performance.
