OverviewAI-generated summary
C. F. Rosenkrans' research focuses on animal reproduction and nutrition, with a specific emphasis on cattle and sheep. Recent work has investigated the efficacy of different estrous synchronization protocols, such as CO-Synch + CIDR, on pregnancy rates in beef heifers and cows. Additionally, studies have examined the physiological changes, specifically in cytochrome P450 expression, in Katahdin ewes fed endophyte-infected tall fescue seed diets during different seasons. This work contributes to understanding factors influencing livestock health and reproductive success.
Rosenkrans holds a strong academic record, indicated by an h-index of 22 and over 2,200 citations across 145 publications. Collaborations within the University of Arkansas at Fayetteville include work with Ken Coffey, Brittni P. Littlejohn, Nicole Noga, and C.R. Looney, evidenced by shared publications. The researcher maintains an active lab website and leads a research group, suggesting ongoing scholarly activity and mentorship. Recent publications in 2021 and 2026 demonstrate continued engagement in research and educational topics.
