Our experience with the GDC could not have been better.

I just wanted to send you a note of thanks for your professionalism, dedication and expertise. As you know, McDonald Ranches bulls recently completed the Genetic Development Center’s Bull Development Program and we could not be more pleased with the data, the condition/health of the bulls and the overall program. Please allow me to explain what prompted us to enroll our bulls.

It is our belief that in attempting to maximize profits, one area we, as producers, have neglected is controlling inputs. While it is important to push and maximize production numbers, it is equally important that we improve efficiencies. We feel like we need to concentrate more on this aspect of production as we move forward in the beef cattle business.

As I am sure you are aware, feed costs account for over 60% of the variable costs in producing beef. As such, it is of paramount importance that we develop cattle that produce more on less. Until recently, we have not had an economical, readily-available means for determining and comparing feed efficiency. The Genetic Development Center and the GrowSafe System provide producers the ability to measure residual feed intake. Research has shown definitively that efficiency is a highly heritable trait. In fact, efficiency can be improved 10-15% in only 3 generations.

With that in mind, McDonald Ranches went in search of a place where we could get that kind of data, compare our bulls to each other and compare our bulls within and across breeds. In the south-central US, there is only one place capable of providing that service; the Genetic Development Center.

Our experience with the GDC could not have been better. We enthusiastically look forward to a continued partnership with the GDC. You run a first-rate program with a top-notch staff and provide data that will help us be more profitable…….can’t beat a deal like that.

With Warmest Regards,

The results received at GDC increased our profit margin when we sold those animals and helped us determine which animals would best serve our breeding program.

Kay Ranch is a seed stock producer of fullblood Wagyu and Wagyu/Angus F-1’s. We have been in the cattle business for close to 40 years. The cattle market has changed dramatically during this time. Today’s market is highly competitive, data driven and we know we need tools to ensure that our business stays up to date. The Genetic Development Center provides us with those tools. When we first visited the facility before their first test, we were impressed with the state of the art equipment, the well planned pen system and the knowledge base of the management. The entire team was eager to make our animals as good as they could genetically be. We have had animals in tests at other facilities, but the results fell short of what we received in our first time at GDC. We were kept up-to-date all along the way, and at the end received valuable feed intake measurements, weights, and ultrasound results. Our bulls came back as the best set of bulls we have ever raised. The results received at GDC increased our profit margin when we sold those animals and helped us determine which animals would best serve our breeding program. We are back again this year looking forward to another positive experience.

Data collected at the Genetic Development Center not only allows for better herd management, but also gives customers additional confidence in their seed stock purchases.  At the 2014 Texas Wagyu Association’s “The Steaks are High” sale open heifers that had been through the Genetic Development Center’s gain test averaged 22% higher prices over those that had not.  This difference demonstrates the value of data to the producer and the customer.
