Using a chainsaw (preferably one from a bp) and a character with decent melee is the best way to harvest besides a maxed out therazino. With a basic chainsaw, 200% melee, and a 145 ovis... I got over 100 mutton, 1K weight in pelt, and 2K hide
You should use Ovis for a mutton farm because mutton is like a less effective type of kibble. Most dinos Love mutton so this is a very useful way to use these!
If you wanna get wool without having to get ovis by just geting vegie cake make a cage with dino gate then get a argy to transport it into the cage then just simply shear it with scissors.
