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.

Resistance to anthelmintic drugs is a threat to equine welfare. Like antibiotics, is restrictive use of anthelmintics necessary to retain their effectivity. Thus, targeted selective treatment, based on individual deworming, was introduced a decade ago. However, we have shown that the prevalence of, …

The purpose of this project is to define the amount of slaked lime needed for a given clay soil. We hypothesise that the amount of slaked lime needed for minimal phophorus loss is dependent on the clay content of the soil. The study will be conducted in a field with a drainage system and measuring …

Increased production and export of products with high added values, e.g. long-ripened hard cheeses, are considered important steps for a positive development of the Swedish dairy sector. Increased investment in Swedish premium cheese will, however, require increased volumes of high quality raw milk …
