Water soluble vitamin needs of weaned pigs

Abstract

Two trials, using 360 pigs weaned at 17-27 days, were conducted to evaluate pig performance as affected by the addition of folic acid, thiamin, biotin, pyridoxine, or ascorbic acid to the diet. Combined data from Trial I and Trial II indicated that adding these supplemental vitamins did not improve daily gain or feed efficiency. These results suggest the addition of these supplemental water-soluble vitamins to a corn-soybean meal 20% whey diet or injection of a B-vitamin complex for pigs weaned at 3-4 weeks of age is not beneficial.
