Effects of Different Housing Systems during Suckling and Rearing Period on Skin and Tail Lesions, Tail Losses and Performance of Growing and Finishing Pigs

Anita Lange, Michael Hahne, Christian Lambertz, Matthias Gauly, Michael Wendt, Heiko Janssen, Imke Traulsen

Published in 2021

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.

The behavior of the sows: Can we predict it?

Paula Arroyo

Published in 2021

Technical article highlighting the importance of ethology in improving pig production. A better understanding of sow ethology can improve animal welfare, management, reproductive efficiency and, therefore, the profitability of the farm. The veterinarian has a new social and educational role to play in improving the welfare of sows and piglets. Staff also need to be trained in ethology, which will enable them to predict the behavioural profile of sows before the first farrowing, improve selection and reduce restraints on animal movement.

Horses' physiological and behavioural responses during undergraduate veterinary practical teaching classes

Lauréline Guinnefollau, Charlotte F. Bolwell, Erica K. Gee, Elizabeth J. Norman, Chris W. Rogers

Published in 2021

Scientific paper investigating the stress responses of horses used in veterinary teaching practice. The indicators measured included heart rate and behavioural indicators suggestive of stress. Limited physiological and behavioural stress responses were observed, suggesting that the horses in question might become accustomed to being handled and being in a teaching environment.

Influence of workload and weather conditions on rolling behaviour of horses and mules

Marina P.F. Luz, Caroline M. Maia, Heraldo César Gonçalvez, José Nicolau P. Puoli Filho

Published in 2021

Scientific paper highlighting that horses roll more frequently after strenuous exercise or bathing, regardless of weather conditions, whereas mules roll more often after strenuous exercise on hot, humid days or after bathing on cold, dry days. It concludes that rolling is an important and frequent behaviour in domesticated equids that should be allowed to be expressed freely on the farm.

The importance of considering age when quantifying wild animals' welfare

Luke Hecht

Published in 2021

A scientific review of work on age-related welfare levels in wild animals, which proposes a  new conceptual framework based on welfare expectancy. This quantifies the welfare of a population of wild animals using individual data on average welfare as a function of age.

Effect of transportation and social isolation on facial expressions of healthy horses

Johan Lundblad, Maheen Rashid, Marie Rhodin, Pia Haubro Andersen

Published in 2021

Scientific paper describing the facial expressions of healthy, pain-free horses before and during transport and social isolation, both of which are potentially stressful management procedures. The following facial features were observed in both cases: increased eye white, dilated nostrils, elevated upper eyelid, elevated inner forehead, exposed tongue, increased ear movements and blinking frequency. Some of these stress markers are already used as indicators of pain.
