Our Genetics
WILKINSON HERD BULLSThe Wilkinsons place great value on the bulls that are walking their pastures. Over the years, they have worked to align these herdbulls with their program’s genotypical and phenotypical needs. Although AI is used extensively, the Wilkinsons still use 2 herd sires for each pasture group. This guarantees that all cows will be covered, no matter how spread out the feed and water sources are. So, all of their herd sires must be carefully chosen to represent the overall goals of their Program, bringing each generation closer to their ideal herd.
The Spring of 2024 brought the first calves out of Barcelona, Kansas, Kachina and Whitewater, and the results were exciting. Their phenotype and genotype meshed perfectly with the Wilkinson cows, resulting in calves that were “good from the start” and had that “spread” between the Calving Traits and Performance numbers, that all beef producers desire.

The WILKINSON’s BREEDING PROGRAM
The Wilkinsons consider a variety of factors in their breeding and management decisions, but the rough arid environment of Southeastern Colorado is probably the most important one. Typical stocking rate is between 75-100 acres/cow, so their cows and bulls must be structurally sound in order to walk the miles they need to for water and grazing. In addition to soundness, the Wilkinsons emphasize strong maternal traits, for which Gelbviehs are known. Cows must have moderate milk production, with good teat and udder structure. Cows calve unassisted out in the pastures and the calf must get up and suck immediately, which is why teat size is so important. Predation can also be an issue so having a good mother is extremely important, as well.
When making breeding decisions, bulls are chosen for their potential maternal, performance and carcass characteristics. Because they are trying to push the envelope with performance, without sacrificing birthweight or mature size and carcass, this selection process is always a challenge. Additionally, not only do the Wilkinsons want to produce more pounds for their customers, but they also want their customers to keep their own replacement females. That is one strong characteristic of the Gelbvieh and Balancer cattle -- they are dual-purpose in that they produce outstanding mamas, as well as performance-oriented steers. Bull selection for their herd sires is based on these basic principles, whether they are selected from their own herd or purchased from other Gelbvieh/Balancer breeders. Over the years, they have found that running multi-sire groups results in an almost 100% breed-up. The added expense of sire testing is easily covered by the increased conception rate.
Heifers are bred to start in March, whereas the cows start in early April. The hope is to avoid the severely cold winter storms while getting closer to green grass. The Wilkinsons normally hold back 45-50 replacement heifers (registered and commercial) and develop them on a heifer development ration, then synchronize and AI breed them to calving ease sires, usually Angus or higher percentage Balancer sires. After one round of AI, they are turned out with calving ease herd sires.
Roughly 75% of the registered cows are also AI bred, allowing them to "customize" each potential calf. They generally look at three specifics: 1) the desire to increase or decrease the Gelbvieh make-up in the calf, 2) the genotypical characteristics to complement the cow's EPD profile, and 3) moderate and structurally correct cattle, with some eye appeal. As with the heifers, the cows are turned out with our herdsires after one round of AI.
The Wilkinsons spend many hours, using the AGA Registry’s Progeny Calculator planning the mating of their cow herd. They start with potential AI sires for each care, matching both the predicted genotype (from the Calculator) and potential phenotype (using knowledge of each cow and heifer). After selecting the AI sire, each cow is paired with a herdsire group, also anticipating optimum genotype and phenotype profile.
