  • Management and nutrition impact on welfare and productivity of commercial poultry species

Brief Biography

Karen Schwean-Lardner is an Assistant Professor at the University of Saskatchewan, working with turkeys, broilers and laying hens. Her work is often multi-dimensional, and examines how various management practices impact not only the welfare and productivity of birds. Her PhD investigated the impact of daylength on broiler production and welfare and her findings are used for broiler lighting program recommendations worldwide. Karen’s other research interests include the stocking density implications for turkeys, impact of daylength on turkey productivity and welfare, effects of toe treatments on commercial turkeys, beak treatment for leghorns, nutrition and behaviour interface for hens, and light intensity for broiler production.
