A scientific paper assessing the welfare of calves in the holding areas of abattoirs in New Zealand, using group and individual animal-based indicators. It proposes relevant indicators, recommending that they should be systematically incorporated into the protocols used to assess the welfare of calves at slaughter.

Scientific paper to determine the percentage of pregnant cows and heifers slaughtered in a medium-sized Austrian slaughterhouse. The observed prevalences are much higher than estimated (6.4% as against an estimated 2.5%). The article recommends that measures should be taken to avoid sending pregnant cows to slaughter for ethical and public health reasons.

A scientific paper to determine the influence of temperature and air enthalpy variations in live pig transport vehicles using welfare indicators. It shows that such variations are greater in winter, and are associated with higher cortisol and lower blood glucose levels in pigs, both indicators of heat stress.

Scientific paper to evaluate the impact of strepsirrhinia education programmes in North American zoos. Respondents consider that these programmes increase positive human-animal interactions, psychological well-being and staff awareness of animal behaviour. The paper suggests that further work on their impact on the welfare of strepsirrhinia is required.

Scientific paper comparing the influence of two ventilation systems (natural and mechanical) on the behaviour and welfare of fattening pigs. It concludes that the mechanical system is associated with a more positive emotional state in the pigs, but that in both systems high temperatures are associated with heat stress, and that the welfare state of the animals decreases during the last phases of fattening.

Scientific paper presenting and testing computational fluid dynamics models under 4 different sets of ventilation conditions to simulate airflow in cage-free chicken houses. The transition to cage-free rearing calls for changes to environmental conditions to ensure the best quality of animal welfare.

A scientific review of the state of the art of 3D imaging systems and 2D cameras as an efficient means to identify pig behaviour. It describes automated methods for the monitoring and study of feeding, watering, lying, locomotion, aggression and reproductive behaviour in pigs.

Scientific paper on work to assess the effects of heat stress on the behaviour of dairy cows using activity sensors to record 6 different behaviours, ambient temperature and humidity. It shows that raised temperatures and a higher heat index lead to an increase in general activity, changes in feeding habits and a decrease in rumination and resting behaviours, all of which are detrimental to animal welfare.

Scientific paper showing that the provision of environmental enrichment for kenneled police dogs has a stress-reducing effect (reduced levels of cortisol metabolites in the stool) and that access to a grassed area reduces the frequency of stereotypic behaviours in dogs with strong stereotypical tendencies.

Scientific paper investigating the impact of pig housing conditions on the incidence of tail lesions. It shows that keeping piglets in their farrowing pen during the lactation period significantly reduces the incidence of tail lesions and mortality in full-tailed pigs.
