How to Castrate Pigs Quick and Easy on the Farm Jenny Graham, July 1, 2024July 1, 2024 When breeding pigs on the farm, you will quickly realize that learning how to castrate pigs is important. Although this may seem like a daunting farm chore, you can do it quite efficiently while minimizing stress to the animal. How to Castrate Pigs: What is Castration? Castration of male piglets is the removal of the testicles. Farmers do this at a young age when the piglets are still nursing and relatively easy to handle. Castration, right on the farm, is quick and easy with the right setup, help, and supplies. Jump to How to Castrate Pigs Best time to Castrate Male Piglets There are different opinions on the best time to castrate piglets. Generally speaking, the earlier, the better. Most farmers have a standard practice of 7-14 days of age. On our farm, we wait until piglets are around 2-3 weeks of age. You can dock piglets’ tails at the same time, if you wish. Some vets advocate leaving piglets intact until they are around 6-8 weeks of age, or two months of age. If this is the case, the surgical castration of pigs should be done securely with a local anesthetic or general anaesthesia. Effects of Castration: Why Castrate Young Pigs? Pork producers castrate male piglets for a few reasons. First and foremost, on our farm, raising meat animals is one of our top priorities. That being said, when we take the time to properly care for them, we end up with the best meat quality. After all, if you are raising animals for meat production, ensuring you properly care for them shows the respect they rightfully deserve. Castration to Prevent Boar Taint One of the primary reasons we prefer to castrate male piglets on our farm is boar taint. Boar taint is a foul, strong smell and taste in pork that comes from a male pig that has reached puberty but has not been castrated. It is similar to the smell of urine, sweat, or feces. It only took one time of cooking pork from a non-castrated male to know that we will always castrate our male feeder pigs. Moreover, when raising animals for meat production, you don’t want anything to go to waste. What Causes Boar Taint? The major compounds that cause boar taint are androstenone and the presence of skatole. Both compounds accumulate in fat tissue. The only effective method of eliminating boar taint is by castration of male pigs. This can be done by surgical castration or by giving the boar taint vaccine Improvac, made by Pfizer. I’ll pass on the vaccine and stick with castration. Can Boar Taint Be Controlled in Other Ways? Scientific studies have debunked many claims that boar taint can be controlled without surgical pig castration or the vaccine. The Facts: The whole carcass of a non-castrated boar will have boar taint. Processing a live animal at a lighter weight or younger age does not show significant differences. Feeding non-digestable carbohydrates does not reduce boar taint or unpleasant odour in pork production. Processing the meat into bacon, ham, or sausage will not hide the odor or flavor. To Prevent Breeding Another reason why we castrate male piglets on our farm is to control breeding. If we didn’t control breeding, piglets would quickly overrun us. Uncontrolled breeding of piglets is irresponsible if you ask me. Behavior Modification It is pretty common for intact male pigs to have more aggressive behavior than castrated males. The behavioral changes that take place after puberty can cause non-castrated pigs to be more aggressive to other pigs and handlers as well. This can be a dangerous situation with a full-grown aggressive boar. Non-castrated males have an increase in sexual behavior, which can cause problems with pen mates. A castrated animal is just safer, easier to handle, and easier to keep. Supplies Needed & How to Castrate Pigs Two of Your Best Farm Helpers- For the castration of piglets, the more secure you have the animal the better. Iodine- Antifungal, antibacterial, antimicrobial. Use it to prep the area for the procedure. Scalpel or Razor Blade- A new scalpel or razor to make a nice clean incision for the surgical removal of the testicles. Blood Stop– This is not a completely necessary item to have on hand but useful to stop minor bleeding. If doing the procedure correctly, at a young age, there should not be heavy bleeding. Blue Kote– Antifungal, antibacterial, antimicrobial. We prefer to use it as a finishing spray. Some folks just use iodine to finish. How to Castrate Pigs Learning how to castrate pigs is one of those farm chores that is necessary but not one that people look forward to. Let’s take a look at how to castrate pigs on the farm. Best Way to Hold the Piglet for Castration We use a porch railing at our barn to secure piglets for castration. Holding the piglet by both hind legs with its head down, drape the piglet over the railing. One helper will secure the hind legs, while the second helper will secure the front legs. Furthermore, we have tried holding piglets on their backs in someone’s lap but much prefer to hang them over the railing. Having them head down has a calming effect contributing to animal welfare. Prepping the Area Once you have the piglet upside down and secured, go ahead and clean the testicles. Use iodine in a spray bottle to thoroughly clean and wipe down the area. How to Castrate Pigs Push up on both testicles, bringing them to the surface of the scrotal sac. Make a clean incision through the skin of the scrotal sac over each testicle. Making the incisions low on the scrotal sac will allow for fluid drainage. Removing the Testicles Once your incisions are made, pop the testicles through the incisions. You’ll want to do this one testicle at a time by gently squeezing them up through the incision. Pulling the Testicles Out Now that the testicle has been pushed through the incision, it’s time to pull it out. While you pull on the testicle, press your thumb against the piglet’s pelvis. This will ensure that the testicular cords break off at the point of your thumb rather than deep inside the body, which may promote the development of a scrotal hernia or inguinal hernias. A quick pull on the testicle and spermatic cord will break the cord and testicle free. You’ll do the same thing for the second testicle. If necessary, the testicle can be freed from the cord using a scraping motion rather than a clean cut. Pulling is recommended because it helps the spermatic cords to close and heal properly. Finishing Up Once both testicles have been removed you should not have any spermatic cords outside the incisions. Clean the area again with a spray of iodine. If there is bleeding that you want to stop you can use a little bit of blood stop powder, but this isn’t always necessary. If done correctly there should be minimal bleeding. Lastly, spray the area with Blue Kote. Some farmers finish up with iodine only. We prefer finishing with Blue Kote, as it seals the wound up with a protective coating. Putting Piglets Back With Momma After the procedure, you’ll want to put the piglets back with their Momma. When piglets are allowed to nurse, they are provided with pain relief from the act of nursing. So, once you are certain there are not any complications or excessive bleeding, they can be put back with Momma. Over the next few days watch for any signs of infection. Complications of Piglet Castration According to the American Veterinary Medical Association, “Potential complications associated with surgical castration include hemorrhage, excessive swelling or edema, infection, poor wound healing, and failure to remove both testicles. It has been suggested that surgically castrated barrows suffer from suppressed immunity, (27) and exhibit higher incidences of inflammation, pneumonia and other diseases. (28) With immunocastration, complications are similar to those of any other injection of pigs approaching market weight. These would include injection site lesions, needles snapping off in the pigs, handling stress to the pigs, and specifically for immunocastration, risk of self-injection to the stockperson.” Having a relationship with a farm vet in your area is always a good idea when raising farm animals. Call your vet should you have any complications. How To Castrate Pigs If raising and breeding pigs is a goal for your farm, learning how to castrate pigs will be important.
