One hundred and twenty baby pigs weaned at an average of 9 days of age and 5.8 pounds were all fed I.S.C. Pre-Starter “75” to 2 weeks of age. Then they were used to evaluate rations containing 0, 5, 10 and 15 percent sugar coming from refined cane sugar; 0, 5 and 10 percent sugar from invert cane molasses; or combinations of the two sugars not to exceed 15 percent total sugar. These rations were compared to one containing 15 percent unrefined cane sugar. Triplicate pens of 4 pigs each were fed the 10 different experimental rations from 2 to 8 weeks of age. Increased levels of refined cane sugar and unrefined cane sugar, but not sugar from invert cane molasses, improved gains and feed efficiency. No excessive scoring was noticed attributable to sugar or molasses at the levels fed.
