For shepherding, your best bet is probably by riding on Chocobo. Even the calves are huge compared to our buffalo (not counting the minion). You're never going to have a clear overhead view of your stock, unless you're on a cliff. Mounted shepherding will be the quickest way to get around your herd and keep them together.
Stabling or housing them is going to be your biggest issue. As calves, it wouldn't be too bad. You could probably use a wider chocobo stable-style building. Once they're fully grown, you're going to need a massive building. I think your best bet for just milking, is probably just having some sort of large stand/slightly fenced area to house one buffalo at a time.
If I think of anything else, I'll try to add it in. I'm certainly no expert, so definitely don't take my word as law.
