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 are suspected in cows in the early to mid-lactation period, resulting in significant economic losses and poor welfare. Being subclinical, SARA lacks clear symptoms, and is therefore difficult to diagnose with existing methods and markers. We propose to fill this gap by identifying metabolites in bio-fluids associated with the onset and progression of SARA using state-of-the-art metabolomics techniques and developing a novel paper-based test for early detection. The development of tests for early detection of SARA could facilitate timely intervention and prevent clinical welfare implications.

The Swedish dairy industry has made significant improvements in animal welfare, feeding, disease control and herd 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 are suspected in cows in early to mid-lactation period, resulting in significant direct and indirect economic losses, and leading to suffering in domesticated cows. SARA lacks clear symptoms, and is difficult to diagnose with existing methods. We propose to fill this gap by identifying metabolites in bio-fluids associated with the onset and progression of SARA using state-of-the-art metabolomics techniques and developing a novel paper-based test for early detection. Our goal is to provide a novel detection method for SARA, support cattle welfare, make the dairy production more sustainable and efficient and promote climate-friendly production through optimal feed conversion.

Glyfosatfritt vallbrott utan ökat växtnäringsläckage
Helena Aronsson

Projektnummer: O-21-23-618 • Status: Pågående • Ansökningsår: 2021

Crop production
Milk

To grow with reduced use of glyphosate is of great concern driven by the requirements for integrated pest management, the risk of herbicide resistance and a potential coming ban on glyphosate. It requires balancing between environmental effects and impact on yield and economy. The project's goal is …

Vallen i nordiskt perspektiv
Johanna Wallsten, Sveriges lantbruksuniversitet

Projektnummer: R-21-41-605 • Status: Pågående • Ansökningsår: 2021

This project aims to create a popular scientific review of the use of leys for livestock. Target groups are the agricultural
sector and industry. The project has five work packages (WP); administration, crop production, harvest and
conservation, feed value for different animals, and economy. The …

Från parcell till kommersiell – samarbete för en uppskalning av svenska proteingrödor
Johanna Olsson, RISE

Projektnummer: JTI-21-82-610 • Status: Pågående • Ansökningsår: 2021

In Sweden, there is both a great potential and a great need for increased cultivation and processing of plant-based foods from alternative protein crops. The overall aim of the project is therefore to increase the production of Swedish plant proteins for food. The objective is to identify …

Travsporten ur ett vetenskapligt perspektiv: körbarhet som ett koncept för att förstå kopplingar mellan beteende, val av utrustning, optimal prestation och god hästvälfärd
Elke Hartmann, Swedish University of Agricultural Sciences (SLU)

Projektnummer: R-22-47-677 • Status: Pågående • Ansökningsår: 2022

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 …

Träning och tävling av travhästar vid kyla och dess påverkan i luftvägar
Miia Riihimäki, Swedish University of Agricultural Sciences

Projektnummer: R-22-47-700 • Status: Pågående • Ansökningsår: 2022

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 …

Bättre hov, bättre häst?
Susanne Eriksson, Swedish University of Agricultural Sciences

Projektnummer: R-22-47-675 • Status: Pågående • Ansökningsår: 2022

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 …

Ergonomi och arbetsställningar hos anställda på ridskolor - en ny mätmetod med smarta arbetskläder
Cecilia Lindahl, RISE Research Institutes of Sweden

Projektnummer: H-22-47-721 • Status: Pågående • Ansökningsår: 2022

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 …

Grovfôr som et lokalprodusert protein- og energirikt fôr til hester
Rasmus Bovbjerg Jensen, Norwegian University of Life Sciences

Projektnummer: H-22-47-714 • Status: Pågående • Ansökningsår: 2022

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 …

Är migrerande spolmasklarver en del av etiologin bakom luftvägssymptom och nedsatt prestation hos unga travhästar? Utveckling och tillämpning av ett serodiagnostiskt test för spolmaskdiagnostik.
Frida Kristina Martin, Swedish university of agricultural sciences

Projektnummer: H-22-47-712 • Status: Pågående • Ansökningsår: 2022

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. …

Validering av nya biomarkörer för hästens astma i flytande vätskebiopsier
Amanda Raine, Uppsala University

Projektnummer: H-22-47-717 • Status: Pågående • Ansökningsår: 2022

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 …
