Parasites are also a concern. It won't necessarily cause them, they have to already be present, but grazing forages shorter than 4 inches in our typically wet climate significantly increases the risk of the livestock picking up parasite larvae from the grass. This is why we both try not to graze shorter than 4 in. And graze both cattle and sheep together, because both are a dead end host for the others parasites. With this system I rarely have parasite issues.
I don't know how true it is,but I"ve heard that taking it to the ground can cause parasites.
