…Soiling has the advantage of increasing the appetite of livestock by giving them fresh raw stems and leaves, preventing the loss of nutrients and vitamins in the feed, and eliminating the need to turn it into hay or silage, but it has the disadvantage that only the amount needed must be harvested each day.
