Physiological and behavioural responses of poultry exposed to gas-filled high expansion foam

June 10, 2013June 25, 2013adminLeave a Comment

Disease control measures require poultry to be killed on farms to minimise the risk of disease being transmitted to other poultry and, in some cases, to protect public health. We assessed the welfare implications for poultry of the use of high-expansion gas-filled foam as a potentially humane, emergency killing method. In laboratory trials, broiler chickens, […]

Physiological responses to low atmospheric pressure stunning and the implications for welfare

June 3, 2013May 28, 2013adminLeave a Comment

In low atmospheric pressure stunning (LAPS), poultry are rendered unconscious before slaughter by gradually reducing oxygen tension in the atmosphere to achieve a progressive anoxia. The effects of LAPS are not instantaneous, so there are legitimate welfare concerns around the experience of birds before loss of consciousness. Using self-contained telemetry logging units, high-quality continuous electroencephalogram (EEG) and […]

The role of extensionists in Santa Catarina, Brazil, in the adoption and rejection of providing pain relief to calves for dehorning

April 18, 2013adminLeave a Comment

The majority of dairy calves around the world are dehorned with methods that cause them pain and distress. In some dairy production systems, extensionists may influence dehorning practices used on farm through their advisory and knowledge-transfer role. The aims of this study were to investigate Brazilian extensionists’ knowledge, beliefs, and behavior regarding dehorning dairy calves. […]
