Business, science behind phytogenics in pig feeds

What do you need to know to use this family of additives with success in pig feeds?

Phytogenics started as essential oils, if only because most, if not all, of the active compounds were previously classified as such. This is because they were used in aromas — hence the essential part of their name that stems from “essence." Otherwise, animals have no absolute requirement for such compounds that would classify them as essential nutrients. The early products were ground up powders of spices and herbs that provided these essential oils, whereas, at best, they were simple extracts. The major problem that prevented these products from bypassing the initial animal test that most feed manufacturers and pig producers accorded them was the tremendous unpredictability in the concentration of active compounds. As such, additive manufacturers moved on to purified extracts of known concentration and even to synthetic compounds.
