National Hog Farmer
In many plants, such as corn and soybean meal, much of the phosphorus is stored in a compound called phytate. Why is this important? There are three reasons. First, the pig cannot digest phytate-bound phosphorus, so it passes through the pig into the manure; this is good for producing nutrient-rich fertilizer to be applied to corn and soybean fields, but not so good for feeding pigs.
