Charolais on Feed:
The Genetics of Feed Efficiency Field Day

August 22, 2013 • Urbana, Illinois

The American-International Charolais Association, co-hosted along with the University of Illinois and the National Program for Genetic Improvement of Feed Efficiency in Beef Cattle, the Charolais on Feed Field Day which offered an opportunity for breed enthusiasts to learn about emerging technologies that could soon benefit producers.

Charolais breeders, commercial cattle producers and other beef industry leaders from across the United States and Mexico attended the event. Click here to view complete coverage.

AICA 50K Genotype Project

The American-International Charolais Association has been working to build a research database of 50K genotypes. This database will serve as the research base to help make the incorporation of DNA into genomically enhanced EPD (GE-EPD) for AICA.

AICA already has available to them 50K (and High Density, HD) genotypes on some animals through various research projects including the Weight Traits Project and
the Bull 2000 project with the Meat Animal Research Center (MARC).

The initial recommendation for AICA to move forward is to establish a research database on 1000 progeny proven sires. This should allow AICA to develop an effective panel with the ability to predict GE-EPD and improve accuracy of selection, especially on younger bulls and females.

Research projects of this size require a breed-wide effort and the cooperation of Charolais breeders is needed to help build the discovery population. The AICA Board of Directors is asking for membership support to submit DNA samples (50K SNP test) on their herd sires as well as those high accuracy sires they've owned in the past.

The results of this project will be of benefit to every member of AICA and those commercial producers using Charolais genetics through GE-EPD that have higher accuracy values for animals at younger ages.

We have worked to build a list of those animals already known to have 50K genotype available so that as few animals as possible are genotyped more than once.

Please see the lists of specific animals that have already been tested in addition to the list of those animals which are of high accuracy and for which 50K's are desired. This list of desired sires was made available through the Animal Breeding faculty at Iowa State University based on informative accuracy in the current AICA genetic evaluation. Genotypes through this project in the discovery population will be owned by the AICA to be used for research and genetic prediction.

While the AICA Board of Directors appreciates that many breeders will cover the cost to 50K genotype those sires listed on the "Desired" list AICA has directed funds get AICA to the targeted number of 1000 informative sires.

Please check these lists periodically as they will be updated as more animals are genotyped. When possible AICA will add more animals to the "Desired" list as funds permit.

For more information regarding sample collection, sample handling and submission of samples please contact the AICA office.

With more than 2,900 active members, the AICA is one of the most dynamic and innovative breed organizations in the country! Members are eligible to participate in a variety of livestock shows, industry conferences, association activities, and educational meetings. The AICA is the official registry of Charolais and Charbray cattle in the United States. In 2007, the AICA had 64,000 active females reported.
