From 185 to 225 lb BW, no differences in ADG, ADFI, or F/G occurred among pigs fed diets without or with vitamin and trace mineral premixes. Then, from 225 to 266 lb
BW, a special premix with megadoses of
vitamin E, vitamin C, Mg-proteinate, and Feproteinate was added to the diets of half the pigs given the previous treatments. Growth performance was not different among pigs fed diets without vitamin or with the KSU and special vitamin and mineral premixes.
Also, meat quality (color, marbling, and
firmness scores; drip, thawing, and cooking
losses; shear force; and Hunter L*a*b*) was
not affected by inclusion of the KSU and
special vitamin and mineral premixes.
