All horses grazing freely are at risk of parasitic diseases. Due to a growing problem with drug resistance in parasites, there is a need to improve the diagnostic methods. One important problem with today's situation is that one diagnostic procedure costs significantly more than one treatment, both in terms of money and in working hours. Thus, there are strong driving forces to treat "just in case" rather than giving treatment only in cases where it is strictly motivated.
We therefore propose a diagnostic system based on microfluidic separation of fecal samples. The samples are treated in different steps so that the eggs of interest can be sorted and then analyzed using primarily cellular phone-based microscopy which is very easy to use for the horse owner, but also using impedance spectroscopy, and DNA analysis.
We expect our microfluidic system for the diagnosis of fecal samples is faster, easier to use, more sensitive, more accurate and less expensive than today's systems.
Alla hästar som betar fritt utsätts för risk att drabbas av parasitsjukdomar. På grund av ett växande problem med läkemedelsresistens hos parasiter finns det ett behov av att förbättra diagnostiken. Ett viktigt problem med dagens situation är att en diagnostisk analys kostar mångdubbelt mer än en behandling, såväl i reda pengar som i arbetstid. Det finns alltså starka drivkrafter att behandla ”för säkerhets skull” snarare än att behandla enbart i de fall då det är strikt motiverat.
Vi föreslår därför ett diagnossystem som baseras på mikrofluidisk separation av träckprover. Proverna behandlas i olika steg så att de ägg som är av intresse sorteras fram och sedan analyseras med främst mobiltelefonbaserad mikroskopi som är ytterst enkel att använda för den enskilde hästägaren men också med impedansspektroskopi och DNA analys.
Vi förväntar oss att vårt mikrofluidiska system för diagnos av träckprover är snabbare, enklare att använda, mer känsligt, mer precist och billigare än dagens system.

Effective communication between driver and horse via rein signals is essential for safety and horse welfare. Good driveability should at best reflect the absence of unnecessary harsh equipment. Yet, many trotters suffer from mouth lesions but associations with equipment, rein tension and motion …

Human athletes that perform strenuous exercise in cold climates have a high prevalence of chronic airway inflammation and airway hyper-reactivity. Cold weather exercise can also cause inflammation in equine airways. The Swedish Animal Welfare Act and the equine sport industry have regulations for …

Racing unshod improves the speed, but not all horses have sufficient hoof quality to run barefoot repeatedly without risking health problems. If measures of the ability to race barefoot based on routinely recorded data can be used as a genetic selection tool, it will improve animal health and …

The work in horse stables is commonly characterised by heavy and monotonous work, a low degree of
mechanisation and often outdated and worn facilities, and studies have shown a high prevalence of musculoskeletal
complaints for employees at riding schools. The objective of this study is to evaluate …

The amount and nutritive content of forages has major impact on equine behaviour, health, and disease. In the Nordic countries, forages for horses consist almost exclusively of grasses, and to a limited extent of legumes. Legumes contain more crude protein than grasses, hence locally produced …

The equine roundworm, Parascaris, is the major pathogenic parasite of foals, but has also been suggested to be involved in mild equine asthma (EA) in young Standardbreds. We intend to develop a serodiagnostic test with a saliva based sampling method for detection of early Parascaris infection. …

Equine asthma is a disease with a significant negative impact on horse welfare and performance. Novel biomarkers for the disease have the potential to support diagnosis and prediction of treatment response. In a previous study we discovered genes that were significantly upregulated in lung …

The Swedish dairy industry has made significant improvements in welfare, feeding, disease control and management. However, diagnosis and prevention of a very common metabolic disorder, subacute ruminal acidosis (SARA), remains a challenge. Even in well-managed dairy herds 11 to 26% of SARA cases …

Forage crops occupy a dominant part of the agricultural landscape in Sweden and form the basis of ruminant diets. Farmers aim to maximize harvest yield while maintaining a high level of forage quality. The proposed project is a partnership between SLU and Dataväxt, and aims to develop a decision …

The goal with this project is to increase the profitability and production efficiency on Swedish dairy farms by renewing
the genetic evaluation of the breeding value of temperament in dairy cows. We want to investigate if automatic
recordings of behaviour using SLU Gigacow on farm level can improve …
