Background

John Wilkins commenced his career in Agriculture in 1966 with a traineeship to study at the University of Sydney. There followed over 35 years in sheep and cattle research (production and reproduction) - with his first appointment in 1971 - working at various DPI locations including Glenfield (now EMAI), Trangie, Tamworth, Grafton and Wagga Wagga, with a period at University of WA for PhD studies.

John has extensive research experience in animal production - diagnosing causes and formulation of strategies to improve sheep fertility; effects of selenium deficiency on growth, wool production and reproduction; development of the technique for diagnosis of pregnancy and litter size in sheep using ultrasound imaging; factors controlling ovulation rate and embryo loss in sheep; induction and management strategies for twinning in cattle; development of immunological control of ovulation rate in cattle; examination of factors controlling follicle development in cattle; use of ultrasound imaging for reproduction and live body composition studies.

Recent research in Beef CRC projects has focused on the interactions of genetics, nutrition and meat science, specifically examining effects of growth paths and differing genotypes on carcass traits and meat eating quality, involvement in development of models to predict growth and body composition, leading to the use of electronic technology for live and carcass composition.

Overseas projects have been a significant component of John’s work involving several projects in China (PRC) – AusAID project on sheep production in Urumqi, Xinjiang Province, PRC; training programs for Kunming Municipal Peoples Government/Animal Husbandry Bureau, Kunming, Yunnan Province, PRC; and most recently ACIAR Projects  - initially, “Increasing Milk Production from Cattle in Tibet”, which led to “Integrated crop and dairy systems in Tibet Autonomous Region”, with a further project “Developing profitable dairy and sheep meat production systems in Central Tibet” (including “Evaluation of ‘new’ pasture species in NSW”), all centred at Lhasa, Tibet Autonomous Region, PRC.
