Why are cattle castrated by farmers and ranchers? Castrating cattle can be done for a variety of management and welfare reasons. I also think about the neighbors' roving bulls and castration. In the end, this is a management tool used by farmers and ranchers. Why castrate your dog, you ask?
When I tweeted for suggestions for a blog post topic, I had a few inquiries concerning castration and the necessity of it. We are not required to castrate our cattle, but like with many other management choices in beef production, this one was motivated by market demand. Customers seek out products that are consistently tasty and pleasant. Hence, manufacturers reply with the means we are aware of helping to achieve it.
A few hours after birth, I castrate my male calves using the band technique. Some breeders opt to wait until the animal is 2 to 4 months old before castrating it with a band or a knife. Some farmers and ranchers wait to castrate their animals until they are at least 7 months old. Male calves are not always castrated. Animals with outstanding genetic and physical traits aren't castrated; instead, they're used as breeding herd bulls. I'll do my best to summarize my justifications for castration for you.
Breeding selection, if I were to offer you just one explanation for why we castrate animals, would be it. That brings up the previously indicated consumer demand. We establish criteria for particular traits in our herd (i.e. weaning weight, muscling to fat ratio, milk production, structural soundness, among many others). To generate a consistent, desirable calf crop, we choose bulls that meet these requirements. We would have heifers bred to their brothers at a young age and would stray from the targeted breeding program if we left all bull calves whole (not castrated). In addition, heifers that are bred too soon are not permitted to develop into their maximum growth potential as cows.
Why decide to band soon after giving birth?
Any sort of stress has an immediate effect on a calf's immune system, appetite, and overall performance. If we can castrate, vaccinate, etc. calves while they are still nursing their mothers in a familiar environment, at a younger age, we decrease the trauma on that animal. The calf experiences less stress, has a strong immune system, and a good appetite.
How does castration impact the quality of beef?
Have you ever tasted the difference between beef from an 18-month-old steer and an older bull? Different foods have different flavors, textures, fat contents, and general palatability. Higher quality grades, more consistent tenderness, and marbling in beef are all caused by lower testosterone levels. With their money, consumers have opted for the flavor of steer beef over bull beef. Because to increased muscle pH, early castration reduces the quantity of "dark cutters."
Why not castrate the cows and leave the bulls alone?
Indeed, we could do that. There is less control over breeding plans and seasons, less consistency in the beef product, and intact male cattle tend to be more aggressive.
In the end, we castrate cattle because, in comparison to bulls, steers sell for more money, perform better after weaning (i.e., are more sustainable), and are unable to breed their sisters throughout the grazing program following weaning. We worry about the stress and immune system of our cattle, thus we want our heifers to be allowed to mature without the stress of any early pregnancy and castrate early.
Maybe it all comes down to being concerned about the wellbeing of our livestock while meeting demand from customers.
