Från hav till mule - alger minskar metanemissioner från mjölkkor

The purpose of this project is to investigate to what extent substances in algae inhibit microbial methane formation in cows. Several substances, so-called bioactive substances, in red, green and brown algae, have a significant methane reducing effect. These are promising results but in order to reach a commercial product with efficient methane-reducing effects, knowledge of the effect on the cows' microflora by these substances is needed. This study will use algae substances, which in already funded projects have been identified to give effects when fed to cows, and further investigate the impact on these on the rumen microbial community. In addition we aim to investigate the possibility of optimizing the substances in algae through a more controlled cultivation. Reduced methane production will strengthen the ompetitiveness of the dairy and also beef industry.

Syftet med detta projekt är att undersöka i vilken omfattning substanser i alger hämmar mikrobiell metanproduktion i kor. Flera substanser, s.k. bioaktiva substanser, i röda, gröna och bruna alger har en signifikant metanreducerande effekt. Detta är lovande resultat och för att kunna ta fram ett effektivt kommersiellt metanreducerande preparat behövs kunskap om effekten på kornas mikroflora av dessa substanser. Denna studie planerar att nyttja resultat från redan finansierade studier där effekten av utfordring av alger på ko-nivå identifieras. Utifrån dessa studier vill vi i detta projekt undersöka olika bioaktiva substanser och deras inverkan på mikroorganismerna i vommen och om det går att optimera innehållet av substanserna i algerna genom en mer kontrollerad odling. En minskad metanproduktion kommer kunna stärka konkurrenskraften inom mjölk-, men även köttbranschen.

Selektiv avmaskning mot blodmask – risker och möjligheter
Eva Tydén, Sveriges Lantbruksuniversitet

Projektnummer: H-15-47-097 • Status: Pågående • Ansökningsår: 2015

Development of resistance to anthelmintics is a threat to equine welfare. As with antibiotics, restrictive use with anthelmintics in order to retain the effect is essential. Current recommendation for deworming is targeted selective treatment to individuals shedding a certain amount of parasite …

Hösilage"intolerans" hos häst?
Cecilia Müller, Sveriges Lantbruksuniversitet

Projektnummer: H-15-47-063 • Status: Pågående • Ansökningsår: 2015

The purpose is to examine haylage 'intolerance' in horses, which is expressed as diarrhoeic faeces in some horses when they are fed haylage (sometimes also when fed hay). A typical appearance is two-phase faeces - one solid and one liquid. It is not known why or how this condition appears, and it …

Medicintekniska produkter – innehåll och effekt på ledinflammation
Maria Löfgren, Sveriges Lantbruksuniversitet (SLU)

Projektnummer: H-16-47-182 • Status: Pågående • Ansökningsår: 2016

Joint inflammation (osteoarthritis) is a common cause of lameness in horses. There is a need for safe and effective treatments of the disease. Blood derived autologous biological products such as autologous conditioned serum (ACS) and platelet-rich plasma (PRP) are used as intra-articular …

Från unghäst till atlet -förändringar över tid av rörelsesymmetrin hos trav- och ridhästar.
Marie Rhodin, Sveriges Lantbruksuniversitet

Projektnummer: H-16-47-178 • Status: Pågående • Ansökningsår: 2016

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 …

Hälta eller lateralitet: när är en rörelseasymmetri betydelsefull?
Marie Rhodin, Swedish University of Agricultural Sciences

Projektnummer: H-17-47-286 • Status: Pågående • Ansökningsår: 2017

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 …
