Influence of testosterone on the docility of German Simmental and Charolais heifers during behavior tests

In beef cows, docility is important for animal welfare reasons, the farmer’s and veterinarian’s safety as well as for economic reasons. The hormone testosterone is often mentioned in the context with aggressions and docility. The present study tested the hypothesis that higher testosterone levels in beef cows are associated with more aggressive behavior and lower […]

Coat and claws as new matrices for noninvasive long-term cortisol assessment in dogs from birth up to 30 days of age

The last stage of fetal development and the neonatal period represent the most critical phases for the mammals’ offspring. In the dog, the knowledge about the final intrauterine fetal development and biology, as well as about the neonatal physiology, remains scarce. Hormonal changes occurring in the last intrauterine fetal phase and during the early neonatal […]

Cumulative stress in research animals: Telomere attrition as a biomarker in a welfare context?

Progress in improving animal welfare is currently limited by the lack of objective methods for assessing lifetime experience. I propose that telomere attrition, a cellular biomarker of biological age, provides a molecular measure of cumulative experience that could be used to assess the welfare impact of husbandry regimes and/or experimental procedures on non-human animals. I […]
