Ash, H., Smith, T. E., Buchanan-Smith, H. M. 2021. The long-term impact of infant rearing background on the behavioural and physiological stress response of adult common marmosets (Callithrix jacchus). Applied Animal Behaviour Science 234, 105169.

Although triplet litters are increasing in captive colonies of common marmosets, parents can rarely rear more than two infants without human intervention. There is however much evidence that early life experience, including separation from the...

Zobel, G., Proudfoot, K., Cave, V. et al. 2020. The use of hides during and after calving in New Zealand dairy cows. Animals 10(12), 2255.

Isolation during calving is a common dairy cow behavior, however it has not been examined in large outdoor group settings. The provision of “hides” was monitored for its impact on calving location and cow–calf behavior...

Loftus, L., Bell, G., Padmore, E. et al. 2020. The effect of two different farrowing systems on sow behaviour, and piglet behaviour, mortality and growth. Applied Animal Behaviour Science 232, 105102.

Farrowing crates have traditionally been used to reduce occurrence of piglet mortality as a result of sow crushing. However the utilisation of traditional farrowing crates has been suggested to contribute to negative welfare for both...

Freitas-de-Melo, A., Ungerfeld, R. 2020. The sex of the offspring affects the lamb and ewe responses to abrupt weaning. Applied Animal Behaviour Science 229, 105008.

Female lambs have a stronger attachment with their mothers and show a greater susceptibility to stressors than male lambs. Male lambs grow faster than female lambs do, achieving a greater nutritional independence from their mothers...

Ceballos, M. C., Góis, K. C. R., Parsons, T. D. 2020. The opening of a hinged farrowing crate improves lactating sows’ welfare. Applied Animal Behaviour Science 230, 105068.

Concerns about the welfare of lactating sows housed in farrowing crates have emerged because crates physically restrict the sows and possibly compromise their behavior and comfort. The aim of this study was to identify how...

Andrade, B. M.T., Freire-Filho, R., Bezerra, B. 2020. The behaviours of a female blonde capuchin (Sapajus flavius) towards her dead infant. Behaviour 157(14/15), 1231-1238.

Here we describe the behaviour of a female blonde capuchin (Sapajus flavius) towards her dead infant and discuss possible explanations linked to the anecdotal event. We conducted our study in a fragment of Atlantic forest...

Maschat, K., Dolezal, M., Leeb, C. et al. 2020. Duration of confinement and pen-type affect health-related measures of welfare in lactating sows. Animal Welfare 29(3), 339-352.

Temporary crating is considered as a step towards improved welfare in lactating sows. Therefore, the aim of this study was to investigate effects of confinement period (CP) and farrowing pen-type (PT) on health-related measures. Four...

Nordquist, R. E., Zeinstra, E. C., Dougherty, A. et al. 2020. Effects of dark brooder rearing and age on hypothalamic vasotocin and feather corticosterone levels in laying hens. Frontiers in Veterinary Science 7, 19.

Chickens cannot independently thermoregulate at hatch and lack opportunity to behaviorally thermoregulate with a hen in the egg layer industry, thus barns are heated to thermoneutral temperatures. Dark brooders are low-energy-consuming hot plates, which may...

Brown, M. E., Torkelson, M. R., Olsen, G. H. et al. 2020. Comparison of fecal glucocorticoid metabolite concentrations in hand‐ versus parent‐reared whooping cranes (Grus americana). Zoo Biology 39(4), 276–280.

Endangered whooping cranes (Grus americana ) have been produced in captivity for reintroduction programs since the 1980s, using techniques such as artificial insemination, multiple clutching, and captive‐rearing to speed recovery efforts. Chicks are often hand‐reared...

Bailoo, J. D., Voelkl, B., Varholick, J. et al. 2020. Effects of weaning age and housing conditions on phenotypic differences in mice. Scientific Reports 10, 11684.

Poor reproducibility is considered a serious problem in laboratory animal research, with important scientific, economic, and ethical implications. One possible source of conflicting findings in laboratory animal research are environmental differences between animal facilities combined...
