Dr. Hanlon’s research focuses on the integration of reproduction, endocrinology, metabolism, growth and management using molecular, biochemical and physiological approaches to support the reproductive success of poultry species and the industry. This includes investigations into the impact of lighting management, feeding regimens and housing on egg production rates in laying hens and fertilization and hatchability rates in broiler breeder flocks.
