USAID program to develop disease-resistant chickens

Published on: Oct 31, 2013

A new program that will identify genes crucial for breeding chickens that can tolerate hot climates and resist infectious diseases — specifically the devastating Newcastle disease — has been launched under the leadership of the University of California-Davis.

The global economic impact of virulent Newcastle disease is enormous. The project is particularly important for Africa, where infectious diseases annually cause approximately 750 million poultry deaths.

The new effort, called the "Feed the Future Innovation Lab for Genomics to Improve Poultry," aims to dramatically increase chicken production among Africa's rural households and small farms, advancing food security, human nutrition and personal livelihoods. The innovation lab recently was established with a $6 million grant from the U.S. Agency for International Development (USAID) as part of Feed the Future, the U.S. government's global hunger and food security initiative.

Huaijun Zhou, principal investigator for the program and an associate professor of animal science in the University of California-Davis College of Agricultural & Environmental Sciences, noted that disease resistance is one of the most economically important traits for poultry production but also challenging to achieve through genetic selection and traditional breeding alone.

"We are thrilled by the opportunity to apply cutting-edge technology and advanced genomics to solve this problem in poor, developing countries," said Zhou, whose research focuses on the relationship between genetics and the immune system.

"Developing a chicken that can survive Newcastle disease outbreaks is critical to increase poultry, meat and egg production in Africa and in other regions of the world," said David Bunn, director of the new innovation lab. "Increasing the production of chickens and eggs can have a dramatic impact on the livelihoods of poor rural communities."

Homestead and small-scale poultry production is considered to have tremendous potential for alleviating malnutrition and poverty in Africa's climate-stressed rural communities. Improving the productivity of such poultry operations also promises to improve incomes and nourishment for women and children, who typically raise poultry for both income and food in Africa, an announcement said.

Collaborating with Zhou and Bunn at UC-Davis are Rodrigo Gallardo, an assistant professor in the School of Veterinary Medicine, and Ermias Kebreab, a professor in the department of animal science. Also involved are Iowa State University animal science professors Sue Lamont and Jack Dekkers; Boniface Kayang, head of the department of animal science at the University of Ghana; poultry health expert Peter Msoffe of Sokoine University of Agriculture in Tanzania, and Carl Schmidt, a professor of animal science at the University of Delaware.

    We appreciate such scientific explorations which will help alleviate hunger, poverty and vulnerability. I wish we could have access to such/those chickens before the end of the year here in Zambia. With these positive developmental strides towards feeding the future, many hungry billion people will be afforded a chance of survival. Thumbs up to California University - Davis.
