Livestock temperament and behaviour – the relationships between cattle temperament and productivity, product quality, physiology and welfare. Improving the understanding and measurement of temperament. Livestock welfare.
Muscling in beef cattle – selection for visual muscle score in British cattle breeds. The impacts on carcase yield and quality, maternal productivity, genetic and physiological factors.
Linda joined the Department as a technical officer at Grafton Research Station in 2002. She moved to the Armidale Beef Centre in 2005, and after completing her PhD gained a research position in 2010. With a background in ruminant nutrition and rangelands research, she has a broad understanding of livestock systems. Since the retirement of Bill McKiernan she has been the Principal Researcher responsible for the research program on the nationally recognised DPI muscling selection line cattle herd.
Linda collaborates with colleagues from DPI and other research and industry organisations, including the team at Glen Innes Research Station to ensure that this important cattle resource is utilised and applied to solving industry issues.
Linda conducted her PhD on a number of aspects of cattle temperament, and she maintains an interest in this area of research. She is interested in further developing this research to include temperament in broader cattle welfare research.
DPI Muscling Selection Line Herd – the herd is currently part of the Angus Sire Benchmarking Project. This project allows the collection of valuable data on growth, feed efficiency and carcase characteristics of steer progeny from the herd, and fertility and calving performance of the heifer progeny.
Funding is currently being sought to collect retail beef yield data on the steers to gain additional valuable information from the project. Due to the divergent body composition of the selection lines, the herd is also providing suitable animals and data for validation and development of the Beef Specs model, and for the development of 3D cameras for objective animal assessment.
Threat Perception in Cattle – this project is assessing the relationships between current cattle temperament measures and novel measures of anxiety in cattle. The aim is to gain a deeper understanding of aspects of temperament, with a view to providing improved measures in the future. Linda is collaborating with the Welfare group at CSIRO, Chiswick in this research.
