For dairy cattle on pasture in temperate regions, it is largely unknown to what degree hot summer conditions impact energy metabolism, milk yield and milk composition and how effective shade is in reducing these negative effects. During the summer of 2012, a herd of Holstein cows was kept on pasture without access to shade (treatment NS). During the summers(More)
Environmental enrichment (EE) is used in laboratory animal housing to provide stimuli exceeding those of barren cages and is intended to improve the welfare of captive animals. It is argued that when laboratory mice can routinely retreat in sheltering objects when humans are present, they do not habituate to humans and continue to shy away, thereby(More)
The Psittaciformes are a large order of landbirds comprising over 350 species in about 83 genera. In 2009, 141 published studies implicated parrots as research subjects; in 31 of these studies, 483 individuals from 45 different species could be considered laboratory animals. Amazons and budgerigars were by far the most represented psittacine species. The(More)
Most commonly, salivary cortisol is used in pig stress assessment, alternative salivary biomarkers are scarcely studied. Here, salivary cortisol and two alternative salivary biomarkers, haptoglobin and chromogranin A were measured in a pig stress study. Treatment pigs (n = 24) were exposed to mixing and feed deprivation, in two trials, and compared to(More)
Using behavioural indicators of thermal discomfort, that is, shade seeking, panting scores (PS) and respiration rate (RR), we evaluated the effect of hot summer conditions and shade, for a herd of adult Holstein dairy cows and a herd of Belgian Blue beef cows kept on pasture in a temperate area (Belgium). During the summer of 2012, both herds were kept on(More)
Radiotelemetry has become a very popular biotelemetric tool for measuring physiological parameters such as heart rate, blood pressure, body temperature and muscle activity, as well as general behavioural activity in undisturbed, freely moving animals. In most studies using this technique, adult subjects are used. However, sometimes an ontogenetic approach(More)
Due to the high prevalence of obesity in some horses and ponies (especially in the leisure horse sector), effective and safe weight loss strategies are required. The present study evaluated the effect of two different energy restriction rates on physical, morphometric and welfare parameters in 18 obese (body condition score [BCS] 7-9/9) Shetland geldings.(More)
Pig vocalisations convey information about their current state of health and welfare. Continuously monitoring these vocalisations can provide useful information for the farmer. For instance, pig screams can indicate stressful situations. When monitoring screams, other sounds can interfere with scream detection. Therefore, identifying screams from other(More)
