Abstract
Two experiments were conducted to determine the effects of lactose, sucrose, and molasses in simple and complex diets for nursery pigs. In Experiment 1, 210 weaned pigs (4.6 kg) were used in a 30-day growth assay. Treatments included complex diets with 100 g crystalline lactose/kg, and 50% or 100% of the lactose replaced with sucrose or molasses. Overall, replacing lactose with sucrose or molasses did not affect weight gain, feed intake, or efficiency of feed utilization. Surprisingly, diets with molasses supported greater overall weight gain than diets with sucrose (P
