Dr. Zuidhof was the first in the world to develop a transformative precision feeding system to control individual feed intake in group-housed chickens. Over the last 10 years, his research team has been able to consistently achieve very high flock uniformity (coefficient of variation for body weight < 1%). The system is also proving to be an excellent way to remove confounding body weight variation from experiments so as to better elucidate physiological and metabolic mechanisms that contribute to reproductive success in poultry. In addition to its practical commercial potential, the precision feeding system facilitates high quality research with free-run birds, directly addressing the societal issue of animal confinement.
