I only have 12 heads of cattle (1 young bull, 2 steers, 2 cows, 5 yearling heifers, 2 heifer calves) but I take pleasure in the fact that I can walk up to any of them in any part of the field to check them out, look at ears, eyes, hoofs, udders, what ever I need to check......and I don't have to have treats or feed to do it. All of my cattle enjoy being brushed, they stand in line and wait to be brushed - it's so funny to watch them.
They understand that I'm the boss..! There have been several times one gal got the end of my boot planted in her nose because she wanted to be pushy - she's now my best yearling.
We don't have a chute - only an old style stancion in the first barn stale - that's how we AI, give shots, or do whatever we need to do.
The 2 cows were my bottle babies 3 yrs ago, 3 born on the property, the others were purchased from another farm to my property.
I mostly work the cattle by myself so I needed them to be tame. They even understand the words "backup", and "no", and "go to your feed bunker", they do what is indicated by the words.
As for pets -- I wouldn't say mine are pets, we butcher a steer every year for our own consumption, we sell to other people. I know when it's time cull.
I had a Jersey/hereford mix that amazed me. She was the herd leader (I say was because we sold her - she suckled other cows) I was putting feed in the bunker - it was getting dark, my husband moved to one side and spooked this girl, she shifted her weigh towards me, knocked me down. I started yelling "ouch, ouch" even thou I wasn't hurt, yet. She jumped over me then came back to lick my face, I'm guessing to make sure I was ok.
Moral of the story -- me & my cattle are respectful friends but I wouldn't turn my back on any of them, my feet are always planted in fashion for a quick exit, I try to leave myself an out as well as the cattle.
I have to say working with cattle is very enjoyable and I can't remember what I did with my time before we bought our first few 7 yrs. ago.
