While many ranchers focus on preparing their cows for calving, don’t forget about the bulls. After all, a single bull contributes half of your calves’ genetic makeup, making his readiness just as critical. A well-prepared bull can improve the overall quality of your calf crop and help drive better performance in your herd.
So, how do you ensure your bull is up to the task? With his pivotal role in breeding, getting him in top shape before the season kicks off is important. Below, you’ll find five essential tips that will help you ensure your bull is ready to serve your herd effectively, setting you up for a successful breeding season.
Why bulls matter
Bulls are not just another animal on the ranch, they are the secret ingredient that sets a thriving herd apart. They contribute half of every calf’s genetic makeup, meaning one strong bull can influence your entire operation’s quality, growth, and overall performance. A healthy, well-selected bull not only ensures that your cows get bred but also passes on valuable traits that boost the herd’s productivity. In short, without a top-notch bull, even your best cows might not reach their full potential. Your role in selecting and preparing these bulls is crucial to the success of your operation.
Beyond genetics, bulls play a crucial role in maintaining a balanced and efficient breeding program. Choosing the right bull is like investing in your ranch’s future—one with good genetics can lead to easier calving and healthier, more uniform calves. A well-performing bull helps reduce complications and increases overall reproductive efficiency, ultimately saving you time, stress, and money. When you focus on bull quality, you’re not just preparing for the current season, you’re building a foundation for long-term success that goes well beyond just the current season. This long-term perspective can bring a sense of hope and optimism for the future of your operation.
Bulls also help keep the herd dynamic and reduce the need for constant human intervention. Their natural behavior can improve herd balance, ensuring that every cow receives adequate attention during breeding. By keeping your bulls in prime condition and choosing those with proven performance, you enhance the immediate calf crop and set the stage for a robust, profitable operation for years to come. Simply put, a great bull is essential for a healthy, productive herd.
Tip#1: Socialize Your Bulls
If you have a small cow herd and only use one bull, you will not need to follow this tip. But if you use multiple sires, you may want to pay attention to it.
One of the most important tips is to socialize your bulls, especially if you are bringing a new or yearling bull to your place. Introducing a new animal can upset the balance among the animals, and it’s your responsibility to ensure a smooth transition. Giving the bulls a chance to establish their social dominance hierarchy is not just a suggestion, it’s a proactive step you can take to maintain harmony in your herd.
Failure to allow the bulls to establish their social hierarchy can lead to them not focusing on breeding, which can significantly reduce the number of cows that get bred. It’s important to monitor this process to ensure it doesn’t lead to injuries, especially when mixing old and young bulls.
If this is going on, you may want to keep an eye on them. This reason is to ensure they will not take it too far and one of them gets injured. This type of thing can happen when you mix old and young bulls. It is because the younger ones will not always know when to stop.
If you are mixing old and young bulls, keep the younger ones with others their age. The same goes for keeping the older ones with other older ones. Also, in this scenario, you will want to use the older ones first, and then you can utilize the younger ones in the last 3rd of the breeding season. This tactic will be so they can get any of the ones the old guys may have missed.
Tip#2: Acclimate Your New Bulls
This tip is accurate for any cows you will bring to your place. You will want to give them a chance to get used to the climate and surroundings before you put them to work. A general idea is that purchasing your animals within a 200-mile radius of your operation is best. This rule will mean that they are already somewhat acclimated to the climate they will be dealing with.
When bringing them to your place, it’s a good idea to keep them in a pen with a group of steers or pregnant cows while they get acclimated. Keeping them with cows will play on their “safety in a herd” mentality, making the transition much smoother.
Since the bull is already dealing with the stress of a new environment, it’s best to avoid additional stressors like loud noises or sudden movements. These could trigger a dangerous reaction from the bull.
Releasing the bull directly into a new paddock or pasture can trigger its ‘flight response‘, causing it to run away. This could result in the bull being lost and the need to rebuild fencing to prevent future escapes.
Tip #3: Vaccinate for a Strong Start
Much like your cows, your bulls should be updated on all their vaccinations before breeding season. If you are buying the bull just this year, you should be able to get that information from the seller. In this way, you will avoid giving him vaccines that he has already received.
If you have to vaccinate, you should do it 30 days before turning the bull out. This time frame will give the vaccines time to run through the bull’s system. Thus allowing its body to develop the antibodies that it will need.
Regarding which ones to use, the bull should receive the same vaccinations that your cows get. However, if you are unsure, talking with your local veterinarian is always a good idea. This conversation will let you know any potential diseases that you will need to prevent from occurring.
Along with the typical ones such as BVD, it is essential that you vaccinate your bulls for Trich. Trich can cause infertility and even stillbirths, so there is no need to let it show up. I discuss the importance of preventing this from happening in a previous article, “ Preventing Trichomoniasis in your herd“.
Tip #4: Check Your Bull’s Condition Early
Your bull must be in a good BCS before breeding season. He will need to be in optimal condition. This condition will be in order for him to do his job, which will be to service your cow herd.
Now, you may be asking, “When should I be checking the bull’s BCS?“. Well, the rule of thumb is that you should check it for sure about 60 days before the start of the breeding season. Doing it now will give you plenty of time to get him to either gain or lose weight before he has to work.
Just like your cows, he should be at a BCS of at least 5. Though preferably, he should be more like at a 6. You will want him to be a little “fleshy” during his time. That is because it is not unlikely that he will lose some weight with everything he does.
As I mentioned earlier, checking it early enough will give you time to adjust its diet as needed slowly. If the bull needs to gain weight, then you can gradually increase the amount of energy that the bull will be consuming. If the bull is too fat, you can go with a more roughage diet to trim him down.
Tip #5: Test for Breeding Soundness
Before the breeding season kicks off, it’s crucial to make sure your bull is truly up to the task. A simple breeding soundness test, administered by your local vet for a small fee, can assess whether his legs are sound and if his fertility is up to par. This quick check is an essential step in safeguarding your herd’s future, ensuring that your bull can contribute effectively to producing a strong calf crop.
Many ranchers might wonder, “Why test a bull that already looks healthy?” It’s a fair question, but appearances can be deceiving. Research from Washington State University shows that infertility rates among bulls can range from 15% to 25%, even among those that seem perfectly fine. That means nearly one in four bulls might not perform as expected, which could seriously impact your operation.
Knowing for sure whether your bull is capable can save you from costly surprises down the line. A breeding soundness exam is one of the most overlooked yet critical cow/calf operations practices. By taking the time to test your bull before the season begins, you’re not just checking a box—you’re making a smart investment in your herd’s future productivity and profitability.
