Enclosed versus ring feeders: Effects of round-bale feeder type on horse behavior and welfare

In an effort to minimize the amount of hay wasted from a round bale, horse owners generally surround the bale with a round-bale feeder. While often necessary as a supplemental feed source, this feeding technique restricts the space each horse...

Equid assessment, research and scoping (EARS): The development and implementation of a new equid welfare assessment and monitoring tool

The assessment of animal welfare poses numerous challenges, yet an emerging approach is the consolidation of existing knowledge into new frameworks which can offer standardised approaches to welfare assessment across a variety of contexts. Multiple tools exist for measuring the...

Equine Facial Action Coding System for determination of pain-related facial responses in videos of horses

During the last decade, a number of pain assessment tools based on facial expressions have been developed for horses. While all tools focus on moveable facial muscles related to the ears, eyes, nostrils, lips, and chin, results are difficult to...

Evaluation of stress response under a standard euthanasia protocol in horses using analysis of heart rate variability

The effects of a standard protocol for euthanasia on heart rate variability (HRV) as a consequence of stress response were analyzed in this prospective clinical study. The HRV was determined in 40 horses undergoing euthanasia due to various reasons, at...

Skin swabbing is a refined technique to collect DNA from model fish species

Model fish species such as sticklebacks and zebrafish are frequently used in studies that require DNA to be collected from live animals. This is typically achieved by fin clipping, a procedure that is simple and reliable to perform but that...

Spontaneous color preferences in rhesus monkeys: What is the advantage of primate trichromacy?

Color perception and color signaling play an important role in various aspects of animal behavior. However, in mammals, trichromatic vision characterized by three retinal photopigments tuned to peak short, middle and long wavelengths is limited only to some primate species....

Systematic analysis of severity in a widely used cognitive depression model for mice

Animal models in psychiatric research are indispensable for insights into mechanisms of behaviour and mental disorders. Distress is an important aetiological factor in psychiatric diseases, especially depression, and is often used to mimic the human condition. Modern bioethics requires balancing...

The influence of different types of outdoor access on dairy cattle behavior

Pasture access for dairy cows is highly valued both by cows and the public at large. When pasture access is not feasible, farmers can provide cows with alternative forms of outdoor access, such as an outdoor bedded pack, that may...
