João Henrique Cardoso Costa
After two short term visits (2009 & 2011) as a visiting scholar, João joined the UBC Animal Welfare Program full time in 2012 as a Ph.D. student. For his doctoral studies (completed in 2016) João focused on understanding the development of feeding behavior and nutrition of calves and the effects of early life environment and experiences on feed preferences, food neophobia and grazing behavior. This work has contributed to the development of strategies to minimize the negative impact of diet changes and the understanding of practices associated with successful group-housing of calves. In his post-doctoral research, João is conducting a large-scale survey of intensive, high-producing dairy farms in Southern Brazil, with the objectives of quantifying the prevalence and incidence of lameness in free-stall, compost bedded pack and mixed housing farm systems, and to identify environmental risk factors for lameness in this region.

Jennifer received her Ph.D. in 2015 from the interdisciplinary Animal Behavior graduate program at the University of California-Davis, where she also completed a postdoctoral scholarship in the Department of Animal Science. In addition, she has a bachelor’s degree in Psychology from Harvard University. Jennifer’s research on improving cattle welfare has spanned topics including cooling dairy cows efficiently in the summer while conserving potable water, evaluating the welfare implications of muddy underfoot conditions, understanding the motivation of feedlot cattle to consume dietary fiber, and validating behavioral data collection techniques.
