My specific areas of research interest include the effects of nutrient intake and feed ingredient quality on performance and product quality in broilers and broiler breeders. Specific research areas within these topics include; the effects of feed ingredient contaminants (i.e. mycotoxins, bacteria, etc.) on broiler performance, nutritional and environmental factors influencing broiler meat yield and carcass grade, and the effect of nutrient intake patterns on broiler breeder performance. Novel approaches of current interest to the poultry industry include trials examining nutritional and environmental impacts on broiler yield and health, trace mineral influences on avian cellulitis and immunity, and feeding program influences on broiler breeder egg production and body composition.
