Specific areas of interest include food intake regulation, dietary effects on behavior, and dietary requirements of turkey breeders. Considerable research has been conducted on the role of various neurotransmitters on food intake regulation within the brain, and how diet can influence these neurotransmitter levels and thereby alter behavior.
Such studies involve injection of neurotransmitters directly into the central nervous system and measurement of neurotransmitter levels in response to various manipulation. In addition, studies have been conducted to examine how dietary energy and protein requirements are affected by stage of reproduction and strain in turkeys.
Finally, research is currently in progress to address environmental concerns. The
effects of dietary supplementation with phytase has shown that this enzyme can decrease
phosphorus excretion while increasing phosphorus digestibility. Further studies are
investigating whether the gene for this enzyme can be placed directly in feedstuffs and
result in improved nutrient availability.
