Reducing reproductive wastage

19 October 2016

Wool grower Greg SawyerResearch by CSU Masters of Philosophy student Greg Sawyer, under the supervision of Dr Edward Narayan, School of Animal and Veterinary Sciences, CSU and Graham Centre Director Prof Michael Friend, has provided much excitement amongst the local merino industry. Greg’s research integrates the fundamental areas of animal science (reproductive and stress physiology), to better understand how females respond physiologically to stressors while being able to maintain and/or enhance reproductive performance and quality within artificial breeding or natural joining production systems.

Applying non-invasive reproductive and stress physiological hormone monitoring techniques in combination with body temperature, wool staple length, nutrition and seasonal climate, Greg will be able to quantify the key determinants of ewe reproductive (ova) quality and wastage, while the research also has the ability to further enhance the application of drone and group management of flocks.

Greg’s desire to delve into this area of research stems from his 25+ year involvement in the industry and the long held belief that Australia needs to breed more merino ewes to increase on-farm livestock production in sustainable ways, research that will also assist sheep breeders globally to reduce reproductive wastage.
