Array for turkey genotyping

Affymetrix introduces Axiom Turkey Genotyping Array, developed in collaboration with the United States Department of Agriculture – Agricultural Research Service (USDA-ARS) along with Aviagen and Hendrix Genetics.

The array will help breeders better understand the genetics of turkeys in order to improve meat characteristics and health. It will enable scientists and breeders to quickly evaluate genetic markers that can be associated with improved traits such as health outcome and fertility.

The genotyping array will also help the industry sustainably address the growing demands of consumers by reducing feed consumption and environmental footprint. Over 45 million turkeys will be served on Thanksgiving Day this year in the United States. This array is expected to help improve turkey populations broadly in the next few years.

The array development was led by Dr Julie Long of the USDA-ARS Beltsville Agricultural Research Center under a public-private partnership with Hendrix Genetics, Aviagen, and Affymetrix.

The Turkey Genome Sequencing Consortium led the efforts to sequence the turkey genome. The SNP marker discovery effort was led by Prof. Martien Groenen of the Animal Breeding and Genomics Centre at Wageningen University in the Netherlands, and was funded by USDA’s National Institute of Food and Agriculture. The SNP markers on the turkey array were selected by Dr. Curt Van Tassell of the USDA-ARS Beltsville Agricultural Research Center. The commercial launch of the array by Affymetrix allows the entire avian and animal genetics community to benefit from the effort.

“The domestic turkey is an economically important source of meat for consumers in the United States,” stated Dr Julie Long of USDA-ARS. “The research performed with this array will help advance the understanding of genetics in turkey, especially for traits that are difficult to predict such as disease resistance and fertility. Understanding turkey genetics requires evaluating large numbers of genetic markers with different sample types. We are excited about the prospect of having this array available for both research and enhancing genetic improvement of the domestic turkey.”
