Whereas most nutritionists use a fixed level for most vitamins, when it comes to vitamin E, there are many reasons why such a practice is inadequate and needs adjustment specific to each feed.
Vitamin E is a well-known vitamin in that it is included in almost all animal feeds, being a compound of so many functions. But, if we were to give it a commercial nickname, we could call it the “piglet vitamin” if only because nutritionists and veterinarians often prescribe high concentrations of it for a variety of reasons and purposes. As it happens, vitamin E is not cheap, and quality products are worth their money — after all, vitamins are considered essential nutrients. So, in order to justify the usage of vitamin E at elevated levels in piglet diets, we must first understand its many roles.
