Use the whole toolbox

A good bull can make a cow/calf operation more profitable for years. A poor one can deliver a costly collection of calving complications, disappointing calves and missed opportunities. For beef producers preparing to buy their next herd sire, the difference between those outcomes starts long before the bull steps into the pasture.

That was the central message of the Ohio State Extension Beef Team’s presentation “A Buyer’s Guide to Bull Selection.” OSU Extension Educator Alan Gayler and David Felmley of Clay Run Farms in Licking County shared practical advice on choosing, evaluating and valuing breeding bulls in a cattle market where genetics matter and good animals command serious money.

The bull-buying process begins with a basic question: What is the operation trying to accomplish? A producer selling calves at weaning has different priorities from one retaining ownership through finishing or marketing freezer beef. Likewise, a herd producing replacement females needs a different genetic strategy from a terminal crossbreeding program focused on pounds and carcass value. Those distinctions should shape every subsequent decision, from breed selection to the final bid.

Gayler encouraged cattlemen to examine their herds for weaknesses before shopping for improvements. Are cows being culled because of poor feet and legs, inadequate udders or disappointing calf performance? Are open cows becoming a recurring expense? Are calves consistently falling short of desired weaning weights?

Records can reveal the answers. Without measured performance and consistent recordkeeping, producers are left relying on memory, impressions and the occasional favorite cow. With good information, they can identify weaknesses and select genetics to address them.

That is where expected progeny differences (EPDs) enter the picture. These figures estimate how an animal’s genetics are expected to influence the performance of its offspring. Depending on the trait, EPDs can help predict differences in birth weight, weaning weight, yearling weight, calving ease, milk production, fertility, carcass quality and other economically important characteristics.

The numbers become especially useful when comparing bulls within the same breed. If one bull has a weaning weight EPD of 75 and another has an EPD of 85, the second is expected to sire calves averaging 10 lbs. heavier at weaning, assuming comparable circumstances. That is a predicted difference between their progeny, not a guarantee for every calf.

Breed comparisons require extra care because EPD scales differ among breeds. Across-breed adjustment factors can help translate those differences into a more meaningful comparison. Otherwise, a buyer could mistakenly rank two bulls using numbers that are not directly equivalent.

Their broader advice was to seek balance rather than chase a single impressive statistic. A bull with exceptional growth figures may not deliver the maternal qualities a producer needs. One with outstanding carcass potential may not suit a herd struggling with structural soundness. And a bull selected exclusively for low birth weight could sacrifice valuable growth if the producer overlooks the rest of his genetic profile.

Beyond the numbers, a bull must pass the physical test. Felmley emphasized fertility as a fundamental requirement, urging producers to obtain a breeding soundness examination before purchasing a bull or turning an existing sire out with cows.

A bull that performed last season may have suffered an injury or developed a problem since then. Discovering that failure after most of the breeding season has passed can leave a producer with open cows and a scattered calving schedule. A veterinary examination is a relatively small expense compared with the potential loss.

Sound structure is equally important. Strong feet and legs help a bull travel, mount cows and remain productive over several breeding seasons. Adequate muscle, masculine characteristics and a suitable body shape also matter. Structural weaknesses that seem minor in a young bull can become serious liabilities as he gains weight.

Felmley cautioned producers against overworking young bulls. A mature, healthy bull may handle around 30 cows, while a yearling’s capacity is considerably lower and depends on age, condition and fertility. His practical guideline was roughly one cow per month of age, with actual assignments adjusted to the individual animal. Too few bulls for the workload can mean missed pregnancies and an extended calving season.

The financial discussion brought the selection process into sharp focus. With cattle prices elevated, quality bulls can carry substantial price tags. Yet Felmley argued that buying cheaply is not the same as buying economically.

He offered a useful rule of thumb: The value of approximately five feeder calves can provide a starting point for estimating a reasonable bull budget. Producers should also consider the sale value of their outgoing sire, the number of cows a replacement will breed and the years of service expected.

The math can be compelling. In one example, a bull producing an additional 25 lbs. of weaning weight per calf across 20 cows for three years would generate an additional 1,500 lbs. of calf weight. At an illustrative $3.50/lb., that represents $5,250 in added gross calf value. While actual returns will depend on market prices, the example showed how modest genetic improvements can accumulate.

The calculation also explains why a bull’s purchase price should not be judged in isolation. Buyers must account for feeding, veterinary care, breeding evaluations and the time required to develop a sale-ready animal. A reputable breeder invests in those services and should be willing to stand behind the bull after the sale.

Crossbreeding offers another route to stronger performance when it is carefully planned. Heterosis, or hybrid vigor, can improve traits such as fertility and growth. Matching complementary breeds can also help producers combine maternal strengths with muscle, growth or carcass advantages. However, indiscriminate crossing can produce inconsistent cattle and undermine the original breeding objectives.

The presenters returned to a simple principle: use the whole toolbox. Study EPDs, inspect the animal, verify breeding soundness, understand the breed and choose a reputable breeder who knows the cattle and will offer support. Establish a realistic budget, then resist the temptation to buy a bull that fails to meet the operation’s needs.

A herd sire influences far more than the next calf crop. His genetics can shape replacement females and production for years to come. That makes bull selection one of the most consequential decisions on any farm.
