First genomics breeding program to benefit poultry industry
WEST LAFAYETTE, Ind. - |
Purdue University animal sciences professor Bill Muir is project co-director for the multimillion dollar research effort to determine the viability of using whole genome DNA selection to improve the accuracy and efficiency of breeding methods.
The project will test a novel way to select poultry for traits that are difficult or costly to measure or are not highly hereditary. Traits of interest include bone density, productivity, animal well-being, feed efficiency, yield, egg quality, growth, robustness and disease resistance.
"Finding individual genes responsible for these traits is terribly difficult," Muir said. "Our solution is to use a genomics strategy that is effective because it gets us simultaneously close to all genes and for all possible traits."
This new strategy is called whole genome selection.
Muir is partnering with Hans Cheng of the U.S. Department of Agriculture and two of the largest international poultry breeding companies, Hendrix Genetics in the Netherlands and Cobb-Vantress Inc. of Siloam Springs Ark. The participating companies represent about half of the world's poultry industry.
Using blood to extract DNA from a chick, the breeding value of a particular bird is calculated based on a panel of 60,000 genetic markers that are evenly spaced throughout the chicken's genome. This technique could be used on other species, but is being tested first on poultry due to their short gestation period.
"Poultry has the shortest generation interval of the major agricultural species, and improvements in poultry breeding have tremendous economic potential," Muir said.
The USDA is providing $2.5 million for the research, with another $2.5 million match from the companies. The corporations also are supplying additional research resources, such as birds, facilities and labor, making the true value of the effort in excess of $10 million.
In the last 40 years, poultry production has grown more than fivefold, making it the primary meat consumed in the United States. U.S. poultry producers are the largest exporters of poultry meat in the world.
