Well I was going to fog my steer today, but only had brown vinegar. I didn't use it becuase I wasn't sure if it would be good for the hair, I didn't think it would matter though.
No probably not. I raise show chickens and we put a little in their water and it makes their feathers shine. I assume thats what you were using it for on your calf.
Not sure about thre brown verses the white but we have very hard water and use it everyday we rinse. I also put a gallon in the swamp cooler once a week in the summer.
