Physiological and behavioral indicators of heat stress in cattle are time- and labor-intensive to measure, and difficult to observe in extensive feedlot and pasture settings. We proposed to record respiration rate and standing behavior using unmanned

Use of unmanned aerial vehicles (UAVs) and photogrammetric image analysis to quantify spatial proximity in beef cattle

Autor: John S. Church, David J. Hill, Justin Terrance Mufford, Nancy J. Flood

Publikováno v: Journal of Unmanned Vehicle Systems. 7:194-206

Spatial proximity is an important metric in cattle behaviour, which is used to study social structure, dyadic relationships, as well as grazing and maternal behaviours. We developed an efficient, novel, non-invasive method to quantify the spatial pro

PSI-8 Comparison of heat stress behaviour between different Canadian Bos taurus cattle breeds using unmanned aerial vehicles

Autor: Mark Rakobowchuk, Stefany Rasmussen, Carmen Bell, Matt W. Reudink, John S. Church, Justin Terrance Mufford

Publikováno v: J Anim Sci

Heat stress is an emerging cause of mortality and production loss in Bos taurus beef cattle production in North America. Despite the recent occurrence of extreme heat events in Canadian pastures and feedlots, there is very little heat stress research

The development of a non-invasive behavioral model of thermal heat stress in laboratory mice (Mus musculus)

Autor: Nancy J. Flood, Chris Miller, Mark Paetkau, Justin Terrance Mufford, John S. Church, Gilly Regev-Shoshani

Publikováno v: Journal of Neuroscience Methods. 268:189-195

Background Many behavioral and physiological studies of laboratory mice employ invasive methods such as radio telemetry to measure key aspects of behavior and physiology. Radio telemetry requires surgical implants, which may impact mouse health and b
