Crib biting and equine gastric ulceration syndrome: Do horses that display oral stereotypies have altered gastric anatomy and physiology?

Equine gastric ulceration syndrome (EGUS) and crib biting (CB) are two separate conditions suffered by horses. Previous research has hypothesized causal relationships between these two conditions, whereby the behavior is driven by a requirement to stimulate saliva production to buffer gastric juice. However, to date, there is limited empirical evidence to support this notion. To […]

Intermittent stress in pigs: Effects on behavior, pituitary — Adrenocortical axis, growth, and gastric ulceration

Ninety-six pigs, half females and half castrated males from 12 litters, were housed in 24 groups of four litter mates. From an age of 115 days half of the groups were subjected to chronic stress for 33 days consisting of a schedule of unpredictable, inescapable electroshocks, and half served as controls. Behavior and performance were […]

Behaviour and stress responses in horses with gastric ulceration

Only little is known about behaviour and stress responses in horses with gastric ulceration, despite the high prevalence of this condition. Our objectives in the present study was to (i) describe the severity of gastric ulceration in horses, housed under relatively standardised conditions, and (ii) to investigate whether horses with severe glandular gastric ulceration have […]
