Meanest breed?

I worked with brahmas in Australia. 3 week old calves when cornered in a yard would paw dirt and charge. It was a funny thing to see. We never took horses into the cattle yards with the cows, they would charge. This mans bulls were the gentlest cattle. You could walk up grab them by the neck and lead them.

In general Dairy bulls are mean and cows Ok, and the reverse in beef types.

Worked a 200 purebred Limo herd not too many issues, had more problems with freshed calves Salers, and espesially Char. Many of the Char cows would come over their own calf and the quad to get at me.

The more time you spend with cows the better behaved they will be, but you can never trust them, and you need room. Many times when people are hurt by a gate or trampled etc the cows were not trying to be bad, just they are a lot bigger than us.

I always use a stick when walking thru or working cows. They then assume that it is part of me, not "O he has a stick then today is a bad day"
