Jeff, I personally run 100 head of cows, along with 300 ac row crop and hay ground. I do it all myself. I also have an off the farm job "in my spare time". In my "other spare time", I assist a neighbor with their 700 head cow/calf operation, along with their row crop and hay production. Neither of our farms uses a hot shot. We both sync a good percentage of cows with cidrs, AI, early preg, vaccinate, fly tag, then later in the fall, we normally run them through again to re-preg, pour, worm. So I doubt many people run their cows through the chute much more than we do. And yet we still don't have a hot shot.
Neither of our farms "waste time" because from the very start as calves, they learn the chute and the forward motion, is not painful or uncomfortable. Since we both keep our own replacements, we do not have to re-train them from a farm that uses hot shots.
A question for you Jeff: If every time you went into the local bar, you got whooped up side of the head, would you keep going to that bar? Doubtful, but what if you HAD to? Someone would whoop you up side of the head in the parking lot to get you to go into the bar, and then since it was painful, they had to whoop you up side of the head again to get you to the bar. You then learn that the parking lot was also painful, so then they had to whoop you up side of the head on the highway to get you to go to the parking lot, and then whoop you again to get you to go into the bar and then whoop you to go to the bar. You then learn that the highway wasn't the place to be so you don't go there, so they whoop you to go to the highway, and then..... you get the picture.
But on the other hand, if someone said, "Hey bud, if you go to the bar, I will buy you a drink, and if you are nice, I will even pay for your cab to go home." Well, you might just decide that is a pretty cool place, so no one has to whoop you to go near it.
MCC - I will admit, a feedlot is a bit of a different situation, but not that you fall under this catagory, but I have been to my share of feedlots, and have to wonder if the cattle are smarter than the human help. Read above. Grandin did not get famous because she is wrong and she has worked with the largest feedlots and slaughter houses in the WORLD. She has retrained the help to work livestock without the use of hot shots.
SMO - Just wait till you have to waste time chasing them to come into the pen, which leads to the barn, which leads to the chute and alley. THEN you will know all about wasting time!
A few minutes to allow a cow to move on her own, will save you hours in the long run. Trust me.
