DNA Program : Prime Pursuits

Why is Prime Pursuits interested in DNA?

The goal of this project is to better predict the potential of cattle in our supply chain so that they can be managed to their optimum end point. We hope this information is also valuable to you, the producer, as you make future genetic decisions for your herd.

Prime Pursuits has a unique set of specifications for the carcasses in our program. This means that it is more important to have a consistent carcass than it is to have a carcass with extreme attributes.

By harvesting cattle closer to the ideal carcass specs, the bell curve narrows and outliers that complicate the fabrication process are minimized.

We are pleased to be able to provide information on 5 carcass traits, based on proprietary genetic data from Prime Pursuits supply chain.

The following information will provide details on interpreting your results and answer the popular question: How do my cattle compare?

From Tissue Sample to DNA Insights

An exciting part of our genetic testing program is that all of our models are built based on data collected by Prime Pursuits. Prime Intelligence (PI) data has been used to train models for each of the 5 traits you see in this report. The original dataset was built on records from 2400 animals harvested in 2023. A model was then built using best practice tools for Genomic Selection based on genotypes generated on the LGC 24k Flex platform by Gencove, a leader in genomic technology.

In 2024, we analyzed over 24,000 samples and are excited to continue to incorporate the latest data to the model going forward. Thanks to the data supplied across the PI system, we have a model optimized for Prime Pursuits genetics, environment and practices. With this years’ genotype collections and subsequent harvest data, we anticipate future growth of the model, allowing incremental accuracy improvements. As with all genetic prediction models, this will come with some potential for changes in trait scores. We will be providing guidance ahead of time as we update the model in future years.

This is a unique industry program, and we’re looking forward to learning together with you, our partners how this tool can best be used.

Each animal will have a Genomic Breeding Value (GEBV) for each trait. You can think of a GEBV like an EPD to compare animals to each other within a group. A GEBV of 0 represents the average of the animals tested in the original dataset. All GEBV’s are presented in the units of that trait.

Marbling-

Marbling is important for quality grade, consumer appeal, and a positive eating experience. Prime Pursuits aims to produce an upper 2/3 choice steak, this correlates to a marble number of 500-690.

Yield Grade-

Yield Grade helps to describe the composition of a carcass and percentage of retail product. A lower yield grade indicates less fat to be trimmed resulting in a more valuable carcass.

Backfat-

Backfat is a key component of yield grade but can also indicate the level of finish on a carcass.

Carcass Weight-

Unlike many programs, uniform but moderate sized carcasses are most desirable. This ensures the customer is getting a consistent size product every time they shop.

Ribeye Area-

Like carcass weight, at Prime Pursuits biggest isn’t best. A 13.5 sq. in. ribeye is exactly what the retail customer ordered.
