Integrating measures of fecal glucocorticoid metabolites and giving-up densitites to assess adrenocortical activity and well-being in zoo-housed three-banded armadillos

To monitor adrenocortical activity in zoo-housed species, we propose using physiological and behavioral indicators that are non-invasive and practical to implement. We explore this model in the southern three-banded armadillo (Tolypeutes matacus; armadillo), which is a near-threatened species commonly found...

Physical injuries and hair corticosterone concentration in rabbit kits from single- and group-housed does kept on a commercial farm

In intense breeding programs, rabbits are exposed to numerous stress factors which could affect their welfare and health. It has been suggested that group housing is more comfortable for does and similar to the living conditions of European wild rabbits....

A new strategy for animal research: Attending to dissent

Increasingly, ethical concepts ordinarily reserved for the human research setting have been applied to nonhuman animals in research. This comes at the same time as concerns mount over challenges in translating the results of biomedical research with animals to human...

Housing conditions affect adult zebrafish (Danio rerio) behavior but not their physiological status

Zebrafish is a valuable model for neuroscience research, but the housing conditions to which it is exposed daily may be impairing its welfare status. The use of environmental enrichment and the refinement of methodology for cortisol measurement could reduce stress,...

Effects of castration and sterilization on baseline and response levels of cortisol—A case study in male guinea pigs

An uncontrolled reproduction of animals in human hands should be avoided. To meet this goal, animals are widely castrated, i.e., the gonads are completely removed. Since the gonads are the most important source of sex hormones, this is a serious...

Habituation to livestock trailer and its influence on stress responses during transportation in goats

This experiment was conducted to determine the effects of habituation to livestock trailers on stress responses in goats transported for long periods. Intact male Spanish goats (12-month old; BW = 31.6 ± 0.34 kg; N = 168) were separated into...

Validating the use of box training as a refinement to rabbit handling

In the wild, rabbits are prey animals and so the act of being picked up and handled can be extremely stressful for them. Yet, the most used method of handling laboratory rabbits is to grasp the animal by the scruff,...

Changes in group behaviour in response to a preferred environment reflect positive affect

When observed in their preferred environments, animals display behavioural changes, such as an increase in resting or a reduction in agonism, suggestive of positive affect and improved welfare. However, most studies focus on the behaviour of individuals or, at most,...

Effects of genotype and housing system on rabbit does’ aggressive behaviors and injuries in smallholding conditions

The objective of the study was to investigate the effects of housing (deep litter + concrete floor vs. deep litter + ground soil with the possibility to dig burrows), and genotype (Mecklenburg or Hyplus) on aggressive behaviour, social contacts, does'...
