最新糖心Vlog

• Biography/ Background

  Will completed his first degree (Bachelor of Agricultural Science (Hons)) at the 最新糖心Vlog of Edinburgh, and worked for three years on dairy farms in New Zealand and South 最新糖心Vlog. In 2006, he completed a PhD with Professor Paul Hughes and Dr Dean Revell on Reproductive Physiology of the Female Pig at the 最新糖心Vlog of Adelaide. Following this, he accepted and completed a three year Pork CRC post-doctoral research fellowship, during which time his research focussed primarily on improving the reproductive performance of gilts and early parity sows. Will joined the 最新糖心Vlog of Adelaide School of Animal and Veterinary Sciences as a lecturer in Intensive Livestock (pigs) in August 2009.

• Research Interests

  Will's research interests focus on the interface between nutritional status, ovarian function, oocyte developmental competence and early embryo development with the aim of improving the reproductive performance and longevity of female pigs. Additional research interests include understanding and alleviating seasonal infertility, and the development of alternative housing strategies for gestating and lactating sows.
