Abstract
The primary target of most feed additives is the gastrointestinal tract and could include enhancement of nutrient and energy utilization, modification of the immune status, and/or the enteric microbiota. The vast majority of research into feed additives is focused on managing the postweaning period. Fermentable carbohydrates are available for utilization by the enteric microbiota. Microbial supplements and fermentable carbohydrates are often considered collectively because of a shared purpose in modifying in some way the microbiota of the pig. The use of exogenous enzymes to modify important economic outcomes in intensive pig production has a long history relative to many feed additives, particularly in the case of phytase and are now routinely found included in dietary formulations for various purposes across different phases of production. Mycotoxins are metabolites generated as a consequence of fungal activity. The aflatoxins, fumonisins, zearalenone, tri-chothecenes, and ochratoxin A are the most relevant found in feedstuffs.
