Guests
Professor Peter Hansen
Peter J. Hansen is a faculty member of the Dept. of Animal Sciences at the University of Florida, where has worked since 1986. He is currently a distinguished professor and L.E. “Red” Larson Professor of Animal Sciences. His research focuses on the biology of early pregnancy and development of methods to improve fertility and assisted reproductive technologies in cattle. Emphasis is placed on elucidating pathways by which the mother regulates preimplantation development, minimizing effects of elevated temperature on fertility and identifying genes controlling embryonic survival and thermotolerance. Hansen received the B.S. in Agricultural Sciences from the University of Illinois in 1978 and the M.S. and Ph.D. degrees from the University of Wisconsin in 1980 and 1983. He did a postdoctoral fellowship at the University of Florida from 1983-1984 before joining the faculty at Florida as an assistant professor in 1984

Dr Gordon Refshauge
Gordon Refshauge is a Research Officer in the field of Maternal Efficiency and is based at Cowra Agricultural Research and Advisory Station. He joined NSW DPI in 2008 as a site scientist managing the Sheep CRC2 resource flock, the Information Nucleus Flock (INF).
Gordon's recent studies include examining heat stress on ewe body temperature and pregnancy rate; post-conception feed intake on pregnancy rate; anti-hormone vaccination to improve ewe fertility and fecundity; cause of death in newborn lambs; mineral health of twin bearing ewes grazing cereal crops, mineral health of twin bearing ewes grazing pastures and the National lambing density study.
