Rumen bypass or "protected" fats are processed dry fats created for easy handling and mixing in animal feeds. Normally all dry fats have high melting points, making them insoluble at rumen body temperature as such, dry fats are not as much "protected" as completely insoluble in the rumen such that they have little impact on rumen fermentation.
