	abstract = {Neonatal calf diarrhoea (NCD) is a disease impacting
livestock industries economically and in terms of animal
health and welfare. In New Zealand, the most prevalent
pathogens associated with NCD are rotavirus and
Cryptosporidium (Mawly et al. 2015), but other common
pathogens include coronavirus and Salmonella. By the time
an animal presents with clinical signs of disease, much of
the associated tissue damage to the intestinal submucosa
may have already occurred, hence affecting production.
Therefore, there is a need to develop methods for early
disease detection, which ideally could be incorporated into
automated systems for real-time, remote sensing.
Infrared thermography (IRT) is a non-invasive method
of detecting radiated heat. The use of IRT in livestock and
veterinary applications was reviewed by Luzi et al. (2013).
Studies have shown IRT can be used for early identification
of calves with BRD (bovine respiratory disease) and BVD
(bovine viral diarrhoea), using changes in eye temperature
(Schaefer et al. 2004, 2012). Schaefer et al. (2012)
demonstrated that images could be collected automatically
at a water trough. In dairy calves, the behavioural
information (e.g. number of visits) gathered remotely at
an automatic calf-feeding (ACF) system can be used for
identification of at risk animals (Svensson \& Jensen, 2007;
Borderas et al. 2009). However, the use of these automated
systems has not been fully investigated under New Zealand
conditions, where calves are exposed to different pathogens
and management.},
