Omitting Vitamin And Trace Mineral Premixes From Diets During Late Finishing (190 To 250 LB) Did Not reduce Growth Performance, Carcass Leanness, Or Muscle Quality

Kansas State University Swine Research. Average daily gain; F/G; dressing percentage; tenth rib fat thickness; and depth, marbling, color, and firmness of the longissimus muscle were not influenced by omitting the vitamin and(or) trace mineral premixes from diets during late finishing (190 to 250 lb). Thus, our data suggest that the KSU vitamin and trace mineral premixes can be omitted during late finishing to reduce cost of gain without decreasing growth performance, carcass merit, or muscle quality.
