Our neighbour had an old bull in the squeeze, and I think he was getting branded, and the instant that hot iron touched him, the bull pretty much just inhaled a deep breath, and bend the heck out of the whole works. Later, that bull took a run at his old man (who was farm-wise), and the old man put a manure fork through the bull's nose and into the ground (I'd have liked to see that) Apparently the bull smartened up after that.
Last night I had one of my heiferettes out for a little early grazing on the halter, and just about forgot about her when I went to bed. So I go out, and put her back in the pen with her mother and 3 week old sister... the two of them run up to each other, butt heads and play a bit, then the younger sister goes and starts to nurse on the heifferette, and she just stood there as if it was her calf (I swear cattle do recognize family).
Some of you may remember my big steer Joules, who I sold to a friend of mine in december (about 1500 lbs)... well, he is about 2 weeks away from landing in the freezer, but this same fellow also bought Joule's intact young brother (Hector, ~700 lbs). So last weekend he got Hector home, and he's semi halterbroke (Can be handled, but doesn't lead very well), and he haltered him up and led him out of the trailer, past the piggies and the sheep (that needed close inspection), and was about to bring him into a pole barn, when down in the field Joules gives out a great big bellow, Hector perks his ears, and drags Trent (6'3", 250 lbs) behind him at full speed to go see his brother. So the idea of the barn was scratched, and the two are together now.
