Background

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 effects on ewe fertility, anti-hormone vaccination to improve ewe fertility and fecundity, factors affecting lamb survival and cause of death in lambs and he is also involved in research examining ewe health on grazing cereal crops.

*NSW Department of Primary Industries was formed on July 1, 2004 through an amalgamation of NSW Agriculture, NSW Fisheries, State Forests of NSW and the NSW Department of Mineral Resources.

Qualifications

  • B.AppSc. (Agric) (Hons1) – Charles Sturt University 1999
