Impact
Vitamin applications are used at relatively small inclusions into finished feeds but the impact of this component on the finished feed has major consequences for growth, feed efficiency and reproductive processes. Some vitamins also have significant effects on carcass the quality. The actual values applied in commercial nutrition are also very much a ‘movable feast’ in that genetic improvement constantly changes the game and further research gives new insights. DSM estimate that due to constant genetic change in growing pigs there is likely to be a 1% change every year in overall vitamin requirements.
