Zebrafish (Danio rerio) is a widely used vertebrate animal for modeling genetic diseases by targeted editing strategies followed by gross phenotypic and biomarker characterization. While larval transparency permits microscopic detection of anatomical defects, histological adult...
Studies have been carried out on the effect of large-volume blood harvesting from horses, but they were performed on nonpregnant horses of various breeds other than Icelandic horses. This study aimed to investigate the effect...
Fueled by the recent and controversial brain-wide association studies in humans, the animal neuroimaging community has also begun questioning whether using larger sample sizes is necessary for ethical and effective scientific progress. In this opinion...
In the UK and Republic of Ireland, the European badger (Meles meles) is considered the most significant wildlife reservoir of the bacterium Mycobacterium bovis, the cause of bovine tuberculosis (bTB). To expand options for bTB...
Behavioural scientists are increasingly recognizing the need to conduct experiments in the wild to achieve a comprehensive understanding of their species’ behaviour. For domestic dogs (Canis familiaris), such progress has been slow. While the life...
When disease progression or treatment effects are investigated, pigs are frequently used for imaging studies. We recently showed that prolonged anesthesia with intensive blood sampling and road transportation affect internal organs in non-recovery imaging studies...
Medicating large production animals, such as sows, individually can be challenging, especially when repeated treatments are needed. Intramuscular (i.m.) injections have been shown to be aversive, and an increased reaction could be expected over consecutive...
Many of the fear tests used in the welfare assessments of broiler chickens assume that birds will withdraw from a given stimulus if they are fearful. However, fear test responses may also depend on the...
Sleep is an important contributor to good physical and mental health and an important component of post-surgical recovery. The assessment of dark phase (‘nighttime’) behavior can provide insight into the efficacy of analgesic treatments and...
The Guide for the Care and Use of Laboratory Animals recommends mice be pair or group housed and provided with nesting materials. These provisions support social interactions and are also critical for thermoregulatory behaviors such...
