Biography and Research Information
OverviewAI-generated summary
E. B. Kegley's research program focuses on improving livestock production and animal health, with a particular emphasis on cattle. Kegley investigates the impact of various dietary strategies and feed additives on animal performance, growth, and disease resistance. This includes studies on the effects of different mineral supplements, such as complexed or inorganic trace minerals, and the use of feed additives like bambermycin and monensin in growing steer calves. Additionally, Kegley's work examines the influence of pasture management, including tillage methods and seeding rates for wheat pasture, on forage production and calf performance. Another area of investigation involves evaluating the efficacy of different anthelmintic regimens for beef heifers to improve postweaning performance and reproductive measurements.
Further research extends to understanding the respiratory microbiome of feedlot cattle and its association with disease, including meta-analyses of bovine respiratory disease's impact on the respiratory microbiome. Kegley also explores methods to mitigate livestock health challenges, such as using supplemental condensed tannin to address toxicosis in ewes consuming tall fescue silage. The research group led by Kegley has a strong publication record, with 257 total publications and an h-index of 31, indicating significant contributions to the field. Kegley collaborates with researchers at the Arkansas Agricultural Experiment Station, including Jeremy G Powell and Robin A Cheek.
