Abstract

Two trials were conducted to determine whether pyridoxine or thiamine needs to be added to the diet for weanling pigs. In the first trial, weanling pigs were fed either a control diet or diets containing added thiamin (2.5 or 5.0 g/ton) or pyridoxine (3.5 or 7.0 g/ton). From d 0 to 14 after weaning, pigs fed added pyridoxine had increased ADG and ADFI, with pigs fed 3.5 g/ton of added pyridoxine having the greatest response. Growth performance was not improved by added thiamin. In a second trial, weanling pigs were fed a control diet or diets containing 1, 2, 3, 4, or 5 g/ton added pyridoxine. From d 0 to 14 after weaning, increasing pyridoxine increased ADG and ADFI, with pigs fed 3 g/ton of added pyridoxine having the greatest ADG. Pyridoxine level had no influence on growth performance from d 14 to 35 after weaning. These results suggest that adding between 2 and 3 g/ton of pyridoxine to the diet maximizes ADG and ADFI from d 0 to 14 after weaning.; Swine Day, Manhattan, KS, November 20, 1997
