Sheep

What can the quantitative and qualitative behavioural assessment of videos of sheep moving through an autonomous data capture system tell us about welfare?

Sheep can be exposed to a variety of challenges and failure to adapt to these challenges can compromise their health and wellbeing. Regular monitoring of stock on large-scale or extensive systems may not always be possible, although recent technological advancements...

Development of an automated pain facial expression detection system for sheep (Ovis aries)

The use of technology to optimize the production and management of each individual animal is becoming key to good farming. There is a need for the real-time systematic detection and control of disease in animals in order to limit the...

The effect of electrical head-to-chest stunning on the EEG in sheep

Head-to-body stunning is regarded as ‘best practice' stunning for sheep. The benefits are loss of consciousness followed by cardiac arrest, death, prevention of animal movements post stun/kill and improved meat quality. Commercial equipment places electrodes on the head and back,...

Thermography as a non-invasive measure of stress and fear of humans in sheep

No data have been published on the use of infrared thermography (IRT) to evaluate sheep emotions. We assessed whether this technique can be used as a non-invasive measure of negative emotions. Two voluntary animal approach (VAA) tests were conducted (and...

Positive perception of human stroking by lambs: Qualitative behaviour assessment confirms previous interpretation of quantitative data

Qualitative behaviour assessment (QBA) was used to validate previous published interpretation whether human stroking has beneficial effects on lambs prematurely separated from their mothers. For a period of 8 weeks a familiar human (FH) subjected 22 Romane lambs to a...

Self-administration by consumption of flunixin in feed alleviates the pain and inflammation associated with castration and tail docking of lambs

It can be impractical for farmers to provide pain relief to livestock following husbandry procedures such as castration and tail-docking, particularly in pasture-based systems because animals need to be repeatedly gathered to handling facilities and restrained. We investigated whether voluntary...

Coding and quantification of a facial expression for pain in lambs

Facial expressions are routinely used to assess pain in humans, particularly those who are non-verbal. Recently, there has been an interest in developing coding systems for facial grimacing in non-human animals, such as rodents, rabbits, horses and sheep. The aims...

Animal-based measures to assess the welfare of extensively managed ewes

The reliability and feasibility of 10 animal-based measures of ewe welfare were examined for use in extensive sheep production systems. Measures were: Body condition score (BCS), rumen fill, fleece cleanliness, fleece condition, skin lesions, tail length, dag score, foot-wall integrity,...

The use of a mechanical non-penetrating captive bolt device for the euthanasia of neonate lambs

A non-penetrating captive bolt device, powered by a 1-grain 0.22″ cartridge delivering a calculated kinetic energy of 47 Joules was tested as a euthanasia method on 200 neonate lambs (Ovis aries) of 4.464 kg (SD (Standard deviation) ± 1.056) mean...

Lambs show changes in ear posture when experiencing pain

Ear posture, or the frequency of postural changes, may reflect various emotional states of animals. In adult sheep (Ovis aries), the 'forward' ear posture has been associated with negative experiences whereas the 'plane' posture has been associated with positive ones....
