Objektiv måling av øvre luftvegs obstruksjon i Norsk og Svenske travhester

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.

Nya rotsjukdomar i korn och vete- okända hot mot svensk spannmålsodling
Lars Persson

Projektnummer: O-20-20-472 • Status: Pågående • Ansökningsår: 2020

Crop production

Cereal production is limited by many different factors. Leaf diseases are often well known, while diseases on roots are more difficult to identify. Root diseases are often caused by oomycetes, fungus-like microorganisms that live for years in soil and on old root debris, parasitizing the roots of …

Optimering av svämtäcke som biofilter för minskad avgång av växthusgaser och ammoniak från gödsellager

Meat
Milk

It is well known that storage of animal manure and digestate causes emissions of methane (CH4), nitrous oxide (N2O) and ammonia (NH3). A crust on liquid manure acts both as a physical barrier for NH3 and as a biofilter that oxidize CH4 and NH3. However, N2O can be formed in some crusts, and there …

Insulin dysregulation and hyperinsulinemia is a horse welfare problem that also increase the incidence of the severely painful condition laminitis in horses. Today, no pharmacological treatment is available but recent weak evidence suggest that Sodium-glucose cotransporters (SGLT) inhibitors (e.g. …

Meat

The bacterium Lawsonia intracellularis causes the disease proliferative enteropathy. The bacterium is present in >40% of the Swedish piglet-producing herds and production losses are estimated to 2 900 SEK per sow and year. The disease is spread by faeces and the pigs are usually affected after …

It is generally accepted that muscle enzyme activity (CK and AST) levels in plasma may increase in Standardbreds and Thoroughbreds after exercise and racing, indicating muscle damage. However, in one recent study on healthy Standardbred trotters fed a forage only diet muscle enzyme activity levels …
