The effects of space allowance during transportation and duration of a mid-journey lairage period on measurements of stress, injury, dehydration, food restriction and rest in young calves were assessed during and after transport. Groups of calves were transported for two 9-h journeys (at a space all...

The effects of several aspects of transportation on the behavioural and physiological responses of red deer (Cervus elaphus) were studied. In two experiments conducted in winter and summer, two groups of five adult male castrated red deer (housed at a space allowance of 2.7 m² per deer) were subjec...

In a 2×2 factorial experiment, groups of 6 sheep were moved from individual pens where they had access to hay and water to environmental chambers kept at either 14°C or 21°C. Within each chamber, half the sheep had access to water but they were all kept at a space allowance of 0.41 m²/sheep with...

An operant crate and a push-door were used to measure feeding motivation in Suffolk sheep (2-4 years of age) after 0, 6, 12, 18 and 24 h without feed. In experiment 1 (n=12), sheep had to push a panel with their noses to obtain a feed reward. In experiment 2 (n=14), sheep had to run a race and push ...

Most sheep sent for slaughter in the United Kingdom are sold through livestock markets. This study counted the potentially bruising events at 2 markets handling 12 119 sheep from 549 groups and recorded the bruises on carcases of sheep from these markets. There were 1324 and 744 potentially bruising...

The bruising of sheep carcases results in economic losses to the meat industry and is one indicator of welfare problems before slaughter. In this study the numbers of potentially bruising events and the transport conditions of sheep taken directly from farms to a slaughter house were related to the ...

The resting behaviour of 64 groups of sheep was observed in the lairages of 2 slaughterhouses after transport for about 4 hours in a commercial livestock transporter. The sheep were watched at 5 minute intervals for the initial 3 hours in the lairage pen. The median percentage of time spent lying pe...

Biochemical measurements of stress and injury were determined in 112 groups of sheep arriving at a commercial abattoir either from farms (71 groups, n=1829), local markets (21 groups, n=2125) or distant markets (20 groups, n=3145). Sheep from farms had significantly fewer bruises (0.08/sheep) than t...

Scan samples of the postural, eating and drinking behaviours of 92 groups of cattle, and focal samples of the eating and drinking behaviour of 378 individuals, were made during the initial 3 h in a commercial slaughterhouse lairage. Cattle which arrived from markets spent more time drinking and lay ...

The handling of 39 cattle during unloading and movement to slaughter of 163 was observed at a commercial abattoir. Most potentially traumatic events and handling events occurred while the cattle were in the race. During the initial 3 hours in the lairage pen, 28 cattle from markets spent significant...

This study quantified potentially traumatic events during handling (350 groups; n=3296), and the effect of source and sex class on the occurrence of carcass bruising of cattle (339 groups; n=3270) at 2 commercial slaughterhouses. A mean of 0.13 and 0.97 potentially traumatic events per animal occurr...

Methods to assess changes in the mental state of animals in response to their environment can be used to provide information to enhance animal welfare. One of the most profound changes of mental state observable in mammals is the change between wakefulness and sleep. Sleeping mammals have characteri...

Groups of sheep were observed in a slaughterhouse lairage in order to investigate the factors affecting their ability to rest. 34 groups were observed using a video camera and recorder from arrival to dusk (evening) and from dawn to removal (morning). 19 groups were transported by road to the slaugh...

Protecting farm animals from hunger and thirst is central to good welfare. However, there are a large number of situations where farm animals are exposed to nutrient restriction. Some of these, such as the effects of prenatal nutrition have received insufficient recognition as welfare issues. Genera...

The prevalence of bovine viral diarrhea virus (BVDV) persistency was examined in 12 Holstein dairy herds in Charlottetown, Canada, from Feb. 2009 to Oct. 2009. A total of 469 serum and ear notch biopsy pairs were collected. Depending upon the age and vaccination status, the sampled animals were divi...

Real-time quantitative polymerase chain reaction (qPCR) testing for Mycobacterium avium subspecies paratuberculosis (MAP) in fecal samples is a rapid alternative to culture on Herrold egg yolk medium (HEYM), the traditional antemortem reference test for MAP. Although the sensitivity and specificity ...
