Our Genetics

As everyone who knows us should be aware, there are certain phenotypical traits that we will always put first and foremost in our breeding decisions here at Wilkinson Gelbvieh Ranch.  Things like moderate size, fertility, structural soundness, and disposition pretty much take priority when it comes to selecting our replacement females and herd bulls.  While we were selecting on these visual traits, we have also placed a lot of emphasis on those things that are not easily seen by just looking at the animal.  Things like EPD’s, Indexes, and Ultrasound data are important to us as well.

As with many operations, it is fun – and gratifying – to see how our herd has grown and morphed into what we have out in our pastures today.   Over the past 10-15 years, we have spent a lot of time and energy, improving the genomics side of our operation and the results have been very gratifying.  As you can see, by looking at these genetics trends in our herd, we still value a calf that comes easy, one that will perform and grade on the rail and females that will do the same job for you as they do for us.

Wilkinson’s Genetic Trends, as compared to National Averages - 2007-2025

$FPI (Feeder Profit Index)
Represents how a bull’s progeny will perform in the feedlot, when sold on grade and yield. A higher FPI means higher MB and CW.

Image

$MPI (Maternal Profit Index)
Combines growth and milk data to predict WW performance of calves. Good tool to use if you market calves and weaning and keep replacement heifers.

Image

$TPI (Total Profit Index)
Balances both Maternal and Terminal criteria, for the most diverse set of EPD’s for the overall potential for an animal in a variety of scenarios – selling at weaning, keeping replacement heifers and/or feeding and harvesting cattle on a grid.

Image

BW EPD (Birthweight)
Predicts the difference, in pounds, for BW of calves The lower the number, the lower the expected birthweight.

Image

MB EPD (Marbling)
Predicts differences in the degree of marbling within the ribeye. Greater MB numbers are an indicator of higher carcass value.

Our Herd Bulls

The 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 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.
