Behavioural and brain gene expression profiling in pigs during tail biting outbreaks – evidence of a tail biting resistant phenotype

Abnormal tail biting behaviour is a major welfare problem for pigs receiving the behaviour, as well as an indication of decreased welfare in the pigs performing it. However, not all pigs in a pen perform or receive tail biting behaviour and it has recently been shown that these ‘neutral’ pigs not only differ in their . . . → Read More: Behavioural and brain gene expression profiling in pigs during tail biting outbreaks – evidence of a tail biting resistant phenotype

Tail biting in pigs – causes and management intervention strategies to reduce the behavioural disorder – a review

One of the largest animal welfare problems in modern pig production is tail biting. This abnormal behaviour compromises the well-being of the animals, can seriously impair animal health and can cause considerable economic losses. Tail biting has a multifactorial origin and occurs mainly in fattening pigs. High stocking densities, poor environment and bad air quality are . . . → Read More: Tail biting in pigs – causes and management intervention strategies to reduce the behavioural disorder – a review

Brain gene expression differences are associated with abnormal tail biting behavior in pigs

Knowledge about gene expression in animals involved in abnormal behaviors can contribute to understanding of the underlying biological mechanisms. The present study aimed to explore the motivational background to tail biting, an abnormal injurious behavior and severe¬†welfare problem in pig production. Affymetrix microarrays were used to investigate gene expression differences in the hypothalamus and prefrontal cortex . . . → Read More: Brain gene expression differences are associated with abnormal tail biting behavior in pigs
