A note on: On-farm testing of the behavioural response of group-housed calves towards humans; test–retest and inter-observer reliability and effect of familiarity of test person
In this study, a test of the behavioural response of group-housed calves towards humans has been evaluated regarding inter-observer and test–retest reliability as well as effect of familiarity of test person. On seven commercial farms, 186 group-housed calves at the age of 30–183 days were tested when fed concentrate in their manger. A test person […]
Understanding avian vision: The key to using light in bird management
Vision is a primary and highly developed sensory pathway in birds. Light, both diffuse and wavelength-specifc (e.g., as produced by lasers) has recently been demonstrated as a potential means of effecting changes in timing and consistency of flock response to an approaching vehicle (simulating an aircraft) and as an avian dirsal method. However, in experiments […]
