Well, my wife has raised water buffalo. She grew up in the Philippines. They call them carabao. She never tried to milk one, but says when they have a baby, they will kill you. Mostly with the horns. If they get you down, then the feet come into play. But the prefered weapon is horns. Other times, they are docile. I never had any trouble walking around them and scratching them. She says they train easily, and are smart. Everyone there ties them all the time because they like to escape and disappear. They poke a hole thru the nose and run the rope there and tie a knot on the other side.
A carabao is more picky than a cow when it eats. It won't eat grass that has manure on it or around it. It won't clean up grass, it only eats the top and then refuses to eat more. Since they are tied to a tree, they have to be moved two or three times a day to fresh grass. They need shade or else they get sick and get diarrhea if left in the sun too long. The thick skin is kinda like human skin and sensitive to insects. If they get a wallow full of water or thin mud, they can spend days in there with just the nose poking out.
I don't know what you will do with your buffalo. They can pull a plow all day and are really strong. I saw a hunting show from Florida where they were bowhunting regular old carabao, but these things were smart and wary. It took the guy a few days but he finally stuck one.
The meat is alright, nothing special. It can be tough, but over there, they mainly butcher the worn out working carabao. Plus everything there is cooked well done, or more. I think a well grilled thick steak might be about like American bison, which also isn't that great. Good luck.
