Upper respiratory tract (URT) collapse during exercise is one of the most common causes of poor performance in
sporting horses worldwide. Evaluation of laryngeal/ pharyngeal collapse during exercise in horses is currently graded
subjectively from videoendoscopic recordings on a treadmill or from overground endoscopy. Pilot studies in Equine
clinical cases performed at NMBU reveal that it is possible to measure URT obstruction objectively with pressure
transducers in either the trachea or nasopharynx during treadmill endoscopy. This has allowed us to start categorizing
different forms of URT obstruction as inspiratory/ expiratory, or combined. It has also allowed us to grade obstructions
as barely measurable (change in pressure 0 to 5 cmH20), mild (5 to10 cmH20), moderate (10 to 20 cmH20), severe (
> 20 cmH20). This project seeks to broaden our understanding of Equine airway physiology, and provide an objective
tool to assess the need for surgical treatment & response thereafter.

Kollaps av øvre luftveier under anstrengelse er en av de mest vanlig årsaker til nedsatt prestasjon hos sports hester
globalt sett. Evaluering av kollaps i svelget er gjort subjektivt fra video opptak tatt under tredemølle eller «overground»
undersøkelse. En «pilot studie» nylig utført ved NMBU viste at det er mulig å måle inspiratorisk/ ekspiratorisk lufttrykk i
trakea og svelget i kliniske kasus. Dette har gjort av vi kan begynne å kategorisere ulike typer av øvreluftveis kollaps
som inspiratorisk/ ekspiratorisk, eller begge deler. Vi kan også begynne å gradere ulike alvorlighetsgrad av kollaps
som: 1) så vidt målbar (forandring i luft trykk 0 til 5 cmH20); 2) mild (5 til10 cmH20); 3) moderat (10 til 20 cmH20); eller
4) markant (> 20 cmH20). Dette prosjektet vil øke vår kunnskap i luftveienes fysiologi, og gi oss en objektiv måte til å
vurdere behov for operasjon eller respons på eventuelle inngrep.

Flea beetles are serious insect pests in spring oilseed rape. After neonicotinoid seed treatments were restricted, no effective chemical control methods are currently available for flea beetle control. Crop protection has therefore become a serious limiting factor for growing the crop. In an …

Motor laterality, such as left or right-handedness, is a well-known asymmetric phenomenon in both humans and animals, incl. horses. Concurrently, lameness caused by orthopaedic injury is a common cause for asymmetry. In our study of riding horses in training, 73 % had motion asymmetries, warranting …

Many horses in training show motion asymmetries, but it is not known if these are due to pain caused by training; or due to individual biological variations. The aim of this project is to initiate three cohort studies where changes in motion symmetry will be monitored over time in riding horses and …
