Abnormal/Problematic Behavior

The epidemiology of fighting in group-housed laboratory mice

Injurious home-cage aggression (fighting) in mice affects both animal welfare and scientific validity. It is arguably the most common potentially preventable morbidity in mouse facilities. Existing literature on mouse aggression almost exclusively examines territorial aggression induced by introducing a stimulus...

Stereotypic behavior in fattening bulls

The occurrence of stereotypies in captive animals may indicate restrictions in animal welfare. In cattle, common stereotypies are tongue playing, manipulation of objects, or conspecifics. However, to our knowledge, the occurrence of stereotypies in fattening cattle was only analyzed in...

Foraging enrichment alleviates oral repetitive behaviors in captive red-tailed black cockatoos (Calyptorhynchus banksii)

The relationship between inadequate foraging opportunities and the expression of oral repetitive behaviors has been well documented in many production animal species. However, this relationship has been less-well examined in zoo-housed animals, particularly avian species. The expression of oral repetitive...

Frothy saliva—A novel indicator to assess stereotypies in sows?

The present study aimed at introducing a reliable and more feasible indicator to evaluate stereotypies in sows in comparison with the Welfare Quality® animal welfare assessment protocol for sows and piglets’. Therefore, the indicators for the assessment of stereotypies of...

Importance of basic research on the causes of feather pecking in relation to welfare

Feather pecking is a prominent issue in the commercial egg industry, associated with economic losses and welfare problems. A non-systematic literature search suggests that studies on feather pecking are predominantly concerned with applied research goals. That is to say, they...

Infrared thermography as an indicator of heat loss in fur-chewing chinchillas (Chinchilla lanigera)

Fur-chewing is a common problem in chinchilla (Chinchilla lanigera). It may affect the welfare of animals due to heat loss, thereby possibly impacting food and water intake to maintain body temperature. In this context, infrared thermography seems to be a...

Impact of a cattle brush on feedlot steer behavior, productivity, and stress physiology

The aim of the present study was to investigate the impact of environmental enrichment (EE), in the form of a cattle brush, on feedlot cattle behavior, productivity and stress physiology. Steers were blocked by weight and assigned to one of...

Pigs with but not without access to pieces of recently harvested wood show reduced pen-mate manipulation after a provision of feed and straw

In barren environments of commercial farms, pig often redirect their rooting and chewing behaviours at other pigs, which can lead to tail biting. When materials such as straw are provided, the quantity is usually too small to have an effect....

Pre-weaning socialization and environmental enrichment affect life-long response to regrouping in commercially-reared pigs

Weaning and other regrouping events as routine work in commercial farms cause stress to pigs and compromise their welfare. Several studies found positive outcomes to mitigate weaning stress when piglets were socialized (i.e. co-mingled) or raised with enrichment materials in...
