What comes first…the chicken, the egg, or the bad attitude?

rcher in the Department of Agricultural Food and Nutritional Science at the University of Alberta.

Individual assessments have identified a small number of 'super-hens' that have an incredible growth potential and are also capable of producing many more chicks than usual. The more typical pattern is for the hen to lose some body weight to support egg production. "The trouble with this is that these 'martyr birds' may eventually suffer from burnout when they don't balance their own needs well enough," Dr. Renema said.

Discovery of the exceptional "super-mom" birds that don't fit the textbook norm has opened new doors in the research program. "If the offspring of these special hens are also more efficient, the broiler industry could move forward in leaps and bounds.

As a result of their findings, Robinson, Renema and Zuidhof have broadened their research focus to include exploration of links between hen reproductive attitude and broiler quality. Their work will contribute to the production of high-quality broilers and to the growing research focus on development of high-quality, value-added poultry products.
