OVN in Pigs

Introduction

Buy the OVN Book Now.

Most recommendations for vitamins in swine nutrition are based on studies carried out several decades ago.

The question of revising these values is often discussed, although this is a topic that raises some controversy due to the fact that in some cases the information available is unclear and that commercial interests may at times make the actual need to update recommendations seem less than credible.

Nevertheless, from our point of view, there are several reasons to suggest the need to review recommendations for vitamins (and other nutrients) for swine periodically. These are all covered in this chapter.
