OverviewAI-generated summary
C.R. Looney's research focuses on reproductive physiology in livestock, with a particular emphasis on cattle. Looney's work investigates factors influencing pregnancy rates and reproductive efficiency in beef heifers and cows. This includes studies on the impact of pre-synchronization of ovulation timing and the use of sex-sorted semen in artificial insemination protocols. Looney has also examined the influence of nutritional factors, such as melatonin supplementation, on pregnant beef cows grazing endophyte-infected tall fescue, assessing effects on uterine artery hemodynamics and offspring growth performance.
Further research areas include the evaluation of different artificial insemination protocols, such as CO-Synch + CIDR, and their effects on pregnancy rates. Looney's lab also explores advancements in reproductive technologies, including the establishment and functional characterization of bovine endometrial epithelial organoids and the effects of specific culture conditions on bovine oocyte maturation. Collaborations with researchers from the Arkansas Agricultural Experiment Station and the University of Arkansas at Fayetteville have resulted in numerous shared publications.
Looney holds a h-index of 23 with over 3,000 citations across more than 120 publications, recognizing a significant body of scholarly work. The researcher is identified as a "high-impact researcher" due to high citation counts and remains recently active with publications extending to 2026.
