Overview
Background
Kieren McCosker has expertise in tropical beef production. Kieren completed an Agriculture Science - Animal Science degree (University of Queensland) and later a PhD (School of Veterinary Science, University of Queensland) deteriming the factors associated with reproductive performance in northern Australia beef cows, otherwise known as the Cash Cow project while working in the Agriculture Division of the Northern Territory Government's Department of Industry, Tourism and Trade. In 2021, Kieren commenced working with the Centre of Animal Science, Queensland Alliance for Agriculture, Food and Innovation and comes with approximately 20 years of experience investigating production issues across many facets of the northern beef production system and south-east Asia. Some of his current projects examine the impact of shade and paddock infrastructure on calf mortality, and utilising remote technologies to remotely detect key production events, such as calving and associated maternal behaviours.
