Lefty, maybe it didn't drift so far of coarse as you think. I would say by the responses that disposition is more a factor of environment and handling than heritable trait. No doubt there are some animals that are born with bad dispositions and need to be culled. On the other side of the coin, maybe if we would take a look at how we handle something that we have a preconceived notion of, we can change that disposition. You can take a good protective mother that blows snot and raises heck but will not hurt you and turn her into one mean rip if you are scared of her and treat her like she is going to eat your lunch. We were at a neighbors working cows my inlaws cows through his facility. We had to sort a few of his cows out and pen them seperate when we were done. I don't remember what we were doing exactly, but we had to walk through those cows to get where we were going. One old girl was high headed and had run my brother in law out of the corral several times and seemed pretty serious. The neighbor came by and walk through the corral like he owned the place, I followed thinking he might be in trouble. The cow raised her head but never bothered either one of us, my brother inlaw started through and damn near didn't get back out the gate as she beat the hell out of it. Neither one of us were scared, he was from the beginning. His own cows act the same way, I have been around them for better than 10yrs and never had a problem with cows he won't get in the same pen with.
