Effect of simple and low-cost enrichment items on behavioral, clinical, and productive variables of caged laying hens

Housing layers in battery cages is a practice still used by many countries but it has been criticized because of its influence on behavioral repertoire of birds. We investigated whether simple and affordable enrichment devices alone impact behavior, foot condition and performance of laying hens housed in conventional cages. Hens were divided into plain cages […]

Abdominal skin temperature variation in healthy broiler chickens as determined by thermography

Abdominal skin temperature of healthy broiler chickens was determined by thermography to estimate the normal range of between- and within-bird temperature variation. Effects of potential confounding factors, such as bird’s contention duration, abdominal side, age, and time of day, were also estimated. Mean skin temperature was estimated from thermogram pictures by computer image analysis of […]

Use of thermography to screen for subclinical bumblefoot in poultry

Thermographic imaging is a noninvasive diagnostic tool used to document the inflammatory process in many species and may be useful in the detection of subclinical bumblefoot and other inflammatory diseases. Bumblefoot is a chronic inflammation of the plantar metatarsal or digital pads of the foot (pododermatitis), or both. It is one of the major health […]

The association between infrared thermal imagery of core eye temperature, personality, age and housing in cats

Understanding individual responses to stress is a key aspect of maintaining optimal animal welfare. This is especially important where animals are being kept in sub-optimal environments or where the species may not clearly demonstrate stress. Therefore, the aim of this study was to investigate how stress varies in cats in a cattery environment in association […]

Behavioural and physiological responses of laying hens to automated monitoring equipment

Automated monitoring of behaviour can offer a wealth of information in circumstances where observing behaviour is difficult or time consuming. However, this often requires attaching monitoring devices to the animal which can alter behaviour, potentially invalidating any data collected. Birds often show increased preening and energy expenditure when wearing devices and, especially in laying hens, […]
