Topic:Behavior
Equine behavior encompasses the study of horses' actions, reactions, and interactions within their environment and with other living beings. It includes the examination of innate behaviors, such as grazing and herd dynamics, as well as learned behaviors influenced by training and human interaction. Understanding equine behavior is essential for improving horse welfare, training methods, and management practices. This topic covers a range of behaviors, from social structures and communication to stress responses and problem behaviors. This page compiles peer-reviewed research studies and scholarly articles that explore the various aspects of equine behavior, including factors that influence it and its implications for horse management and welfare.
The use of hay nets and slow feeders as feeding methods in horse management: A semi-systematic review.

Assessment of olfactory sensitivity in horses using positively conditioned scent. Differences in the ranges and capacities of sensory modalities cause horses to perceive their surroundings differently than humans. To date, the horses' sense of smell has been studied mainly regarding social and reproductive behaviour. The role of olfaction in horse management and use also seems to be of utmost importance. The aim of this study was to determine the response to a scent of different intensities by horses of different sexes and types (warmblood horses vs ponies). The study involved 21 adult mares and geldings, of which 15 subjects learned how to complete the required task and we...
What if Horses Were Humans? Comparing Rein Tension and Bit Pressures to Human Pressure Pain Thresholds. Bit pressure and rein tension-induced mouth pain in horses have recently become a significant welfare concern, fueling debates within the equestrian community and beyond. Evidence indicates that bits can cause pain-related behaviors and even oral lesions. Although studying pressure-induced pain in animals is challenging, the similarities in the physiology of pain processing (nociception) across mammals suggest that it is reasonable to assume that pain perception in humans and horses is principally comparable. Therefore, we compared human pressure pain detection thresholds (PPDTs) to reported r...
