Biography and Research Information

OverviewAI-generated summary

R.L. Drysdale's research focuses on animal nutrition and physiology, particularly concerning nutrient digestibility, bioavailability, and the effects of diet on livestock and poultry. Recent publications investigate the determination of calcium digestibility and bioavailability in various limestone sources using broiler chickens and laying hens. Drysdale has also examined the metabolizable and bioavailable energy of soybean gums and soap stocks in different feeding regimens of roosters and broiler chickens. Further research includes quantifying secretory IgA and mucin excretion in roosters and exploring interactions between phytase, protease, and anti-nutritional factors in soybeans. Collaborations include B.W. Parsons, S.C. Wells, M.T. Kidd, and L.S. Parisi, all from the University of Arkansas at Fayetteville, with whom Drysdale has co-authored multiple publications.
