Simplot Land & Livestock offers a cooperative Genetic Evaluation Service for Charolais breeders focused on making genetic improvement in terminal sires.
This system combines industry standard purebred phenotyping, commercial production data, and genomic profiles to deliver accurate EPDs and a terminal-sire selection index focused on producing commercial calves with superior genetic merit through the feeding period. We are dedicated to making long-term improvements to the genetic merit of Charolais terminal sires for both commercial and purebred applications.
The value in our Genetic Evaluation Service™ is derived from an exclusive and extensive database of accurate phenotypes on both purebred and commercial animals specific to Simplot Land & Livestock and a limited number of cooperating Charolais breeders.
There are currently 2,271 Charolais bulls and 1,275 Charolais females with phenotypes and genotypes in our exclusive Simplot Land & Livestock database. Additionally, commercial phenotypes from weaning to harvest have been captured on 15,380 genotyped commercial calves. Individual feed intakes are measured at an in-house GrowSafe System in Grand View, Idaho. A full list of traits in the genetic evaluation with the average EPD accuracy and heritability is shown in Table 1.

Offering a cooperative genetic evaluation allows for the capture of maximum genetic variation represented in the Charolais breed. This allows purebred producers to have access to a set of EPDs where every sire is informed by accurate commercial data and a genomic marker panel, which is not offered by the current model of National Cattle Evaluation. Commercial sires in the evaluation average 17 calves with production phenotypes directly informing the EPD.
Our Genetic Evaluation Service™ returns a full suite of EPDs accompanied by individual accuracy estimates in addition to a terminal-sire index for feeder calf profitability, $FCP. This index combines purebred and commercial performance to return a selection tool revealing overall genetic merit in commercial calves. The result is an accurate suite of selection tools informed by an extensive database of reliable production data.
Breeders can participate with phenotypes collected on contemporary groups of sires accompanied by a DNA sample or a historical genomic SNP profile. We are happy to discuss custom applications to fit your breeding program.
A full progeny test provides access to accurate selection tools to create a comprehensive genetic evaluation. This service includes:
Includes all the service features of the Tier 1 Full Progeny Test with the deduction of GrowSafe Feed Intake measurement.
Includes all the service features of the Tier 2 Full Progeny Test with the deduction of calving data collection.
Purchase of the basic evaluation only requires phenotypes (breeder provided) on a contemporary group of 10 or more Charolais bulls and hair samples for DNA profiling. Phenotypes that can be incorporated into the EPD prediction include BW, WW, ADG, FI, and ultrasound measurements (FAT, REA, MARB).
The evaluation will provide EPDs with accuracy estimates for all traits in Table 1 along with the terminal sire index for feeder calf profitability, $FCP. This evaluation produces accurate EPDs informed by the full database of traits including the commercial production data collected through harvest.
While Simplot Land & Livestock will use comprehensive tools and prediction models to assess criteria for making genetic improvements to a breeder’s Charolais herd, the Simplot Land & Livestock Genetic Evaluation Services™ are based upon information and data provided by the breeder. We therefore cannot and do not guarantee any results or specific outcomes and disclaim any and all implied or express representations and warranties. Breeder grants permission to incorporate breeder data into Simplot Land & Livestock’s exclusive proprietary database in order for Simplot Land & Livestock to perform Genetic Evaluation Services™. Data will not be shared with any outside party without prior written consent from the breeder.
