OverviewAI-generated summary

C.R. Looney's research focuses on reproductive physiology in cattle, particularly concerning artificial insemination, pregnancy rates, and factors influencing offspring development. Recent publications investigate methods to improve pregnancy success using sex-sorted semen, including pre-synchronization of ovulation and delayed fixed-time artificial insemination in heifers. Looney also studies the physiological impacts of grazing endophyte-infected tall fescue on pregnant beef cows and heifers, examining the effects on uterine artery hemodynamics and offspring growth. Melatonin supplementation is explored as a potential therapeutic agent to mitigate negative impacts of fescue grazing.

Further work by Looney includes research into bovine oocyte maturation and the establishment and functional characterization of bovine endometrial epithelial organoids. Other investigations assess the efficacy of different estrous synchronization protocols and fixed-time artificial insemination methods on beef heifers and cows. Looney has a significant publication record, with 117 total publications and 3,031 citations, contributing to a current h-index of 23. Looney actively collaborates with researchers at the University of Arkansas at Fayetteville, including Jeremy G Powell and Brittni P Littlejohn.
