of positive emotions and affect that cumulatively contribute to the scaffolding for positive …

In animals, including humans, free access to high-quality (generally energy-dense) food
can result in obesity, leading to physiological and health problems. Consequently, various …

The qualitative assessment of animal behaviour summarizes the different aspects of an animal's

Qualitative assessments of behaviour integrate and summarize the different aspects of an

Post-mixing aggression in commercially housed pigs can be intense and often results in the
accumulation of skin lesions. The number of lesions (lesion score, LS) has often been used …

In attempting to understand the mechanisms underlying the development of stereotypic
behaviour patterns it is important to determine those environmental factors that contribute to the …

Nest-building in the pig is thought to be stimulated by a pre-parturient surge in prolactin. There
is concern that sows in crates may experience psychological stress as a result of physical …

Maternal undernutrition in pregnancy results in low birth-weights and impaired postnatal
survival in sheep. Largely anecdotal evidence suggests that the expression of appropriate …

Extensively managed animals, often living in harsh and unfavourable environments, need
specific adaptations that promote survivability. This is particularly important at parturition and …
