Why the Right Bull Matters
A bull contributes half the genetics to every calf in your herd for years to come, making him one of the most important purchases you’ll make as a cattle owner. A poor choice can mean calving problems, weak calves, or years of disappointing performance across your entire calf crop.
Start with a Breeding Soundness Exam
Never buy a bull without a current breeding soundness exam (BSE) from a veterinarian, which evaluates semen quality, physical structure, and reproductive organs. A bull can look perfectly healthy and still be subfertile or infertile, so skipping this step is one of the costliest mistakes a buyer can make.
Structural Soundness
Look closely at feet, legs, and overall frame, since a bull needs to travel long distances across pasture to breed cows effectively. Avoid animals with post-legged or sickle-hocked conformation, as these structural faults often lead to early lameness and reduced breeding life.
Birth Weight and Calving Ease EPDs
If you’re buying a registered bull, review his Expected Progeny Differences (EPDs), especially birth weight and calving ease, particularly if he’ll be bred to first-calf heifers. A bull with high birth weight EPDs bred to young heifers is a common cause of calving difficulty and stillbirths.
Temperament
Ask to see the bull handled and observe his reaction to people and pressure, since aggressive or flighty bulls are a genuine safety hazard around family and employees. Temperament is also moderately heritable, meaning a calm bull tends to produce calmer offspring.
Matching the Bull to Your Herd
Consider your cow herd’s frame size and your target market before choosing a bull breed and individual animal. A bull that produces calves too large for your heifers, or too small to meet your market’s expectations, undermines the value of the purchase regardless of his individual quality.
