I am talking about horns on dairy calves folks! Get your head out of the gutter! It’s time to talk about how we dehorn dairy cows.
Horns. You know those things rodeo bulls have? The Texas Longhorns have them too. So do most dairy cattle, even the girls. Horns on cows are not like horns on deer. Both male and female cattle grow them. Despite the cow toy industries seeming need to place horns on every stuffed Holstein, I bet most people have never seen a dairy cow that has horns…. Of course I am reminded everyday that most people have never seen a dairy cow…. with or without horns.
I hope I am not confusing you. Yes, I said that most dairy cows have horns naturally and I also said that it is very rare to see a dairy cow that has horns. How can this be? The simple answer is that dairy farmers dehorn dairy cows.
Is dehorning necessary?
Dehorning calves is one of the most hated jobs on our farm and I would be willing to bet that there isn’t a farmer out there that enjoys doing it. However it is a 100% necessary job on a dairy farm. Cows with horns are not only more dangerous for farmers to work around, they also are dangerous to each other and to facilities. Don’t believe me? Imagine this cow fight with horns. Not pretty. Pokey, pointy, hard things attached to 1500lbs animals does not work out well. This is why we dehorn dairy cows.
On our farm we start the dehorning process by giving a long lasting pain medication an hour before we dehorn. We also use Lidocaine, it’s the same type of medicine the dentist uses before they start drilling on a cavity. The Lidocaine helps to numb the area and makes the dehorning much less painful for the calf and the long lasting pain medicine takes over after the Lidocaine has worn off.[/caption]
Our goal is to make dehorning as low stress and as least painful as possible for our calves. We want our calves to be happy and healthy and to grow up to be happy healthy cows. The tool we use to dehorn our calves uses heat to cauterize the blood flow to the horn so it doesn’t grow. What this means is that it gets really, really hot and you put the metal tip on the horn bud. It doesn’t feel good for the calf. Which is why we numb the area ahead of time. I am sure a horn being used as a weapon against you wouldn’t feel good either. I believe this is the lesser pain.
After being dehorned I watch my calves extra careful and give them extra love. The horn bud will develop a scab and as it heals it will get itchy. I always try to give the calves a few extra scratches when I feed them when they get to this stage. They sure seem to appreciate it. I wish that dehorning didn’t have to happen and we are making big steps in the dairy industry to phase the needs out.
Polled genes are making a big difference!
Right now more and more attention is being paid to using “Polled Genetics” on farms. A “polled” animal is an animal that is missing the gene that tells the calf to grow horns. Farmers can now include polled genetics in the list of attributes they look for in a bull. It takes time to build a 100% polled herd but farms are getting closer all the time. I know I am looking forward to the day I can cross this job off the list forever.
