Welfare concerns associated with pedigree dog breeding in the UK
In the UK, numerous pedigree dogs of many breeds experience compromised welfare due to the direct and indirect effects of selective breeding. Many breeds are selected to have physical conformations which, although perceived by some to be desirable, have direct negative effects upon their welfare. Dogs are regularly bred whose heads are too large and […]
Physiological and behavioural responses of laboratory rats housed at different tier levels and levels of visual contact with conspecifics and humans
Laboratory rats are typically housed in clear or opaque cages on multi-tiered racks. Clear-walled cages allow a view of the room and facilitate visual social contact with neighbouring rats but may induce anxiety due to lack of visual cover. We hypothesized that degree of visibility of humans and conspecifics affects anxiety in individually housed rats. […]
Preferences for toy types and presentations in kennel housed dogs
Toys are often provided for adult dogs housed in kennels, but their effectiveness as environmental enrichment is not well documented. At a minimum, toys need to elicit interest in the animal for which they are intended, before any “enrichment” can be claimed. In this study we have examined short-term preferences for toys with a range […]
The african wild ass conseration status in the horn of Africa
From 1989 to 1996, surveys were made in most of the historic range of African wild asses in Somalia, Ethiopia, and Eritrea. From the 1970s to the mid 1990s populations of African wild asses (Equus africanus, Fitzinger, 1857) in Somalia and Ethiopia have declined from approximately 6 to 30 per 100 km2 to 1 or […]
Home range size, habitat utilisation and movement patterns of suburban and farm cats
The movements of 10 house cats (4 desexed females, 5 desexed males and 1 intact male) living on the edge of a suburb adjoining grassland and forest/woodland habitat, and a neighbouring colony of seven farm cats, were examined using radio-telemetry over nine months. Nocturnal home range areas of the suburban cats varied between 0.02 and […]
Preferences of sheep for different types of pen flooring
In countries where the climate makes it practical with indoor housing during cold periods of the year and access to straw is limited, e.g. Iceland and Norway, housing of sheep on slats or expanded metal floors is common practice. However, European regulations for organic farming require that all animals should have access to a lying […]
Measuring salivary analytes from free-ranging monkeys
Studies of large free-ranging mammals have been revolutionized by non-invasive methods for assessing physiology, which usually involve the measurement of fecal or urinary biomarkers. However, such techniques are limited by numerous factors. To expand the range of physiological variables measurable non-invasively from free-ranging primates, we developed techniques for sampling monkey saliva by offering monkeys ropes […]
Noise in dog kenneling: Is barking a welfare problem for dogs
Noise levels (sound pressure levels, SPLs) were monitored over 24 and 48 h in a number of different types of kennels including shelters, training establishments and research laboratories. Two measures of SPL were used, Lpeak and Leq, over both low (1 Hz-20 kHz) and high (12.5–70 kHz) frequency ranges and using a linear weighting. At […]
Personality traits in the domestic dog
The domestic dog (Canis familiaris) has been subjected to a huge range of selection pressures during domestication that has resulted in a considerable diversity in morphology and behaviour. This, together with the many uses the dog is put to in our society, makes the dog an interesting model for studies of animal personality. However, only […]
Fluctuating asymmetry as an animal welfare indicator — A review of methodology and validity
It has been suggested that fluctuating asymmetry (FA) reflects an animal’s ability to cope with the sum of challenges during its growing period and, thus, is a potential welfare indicator. In this review we investigate the evidence of associations between FA and other welfare indicators measured at the level of the individual and of effects […]
