The aim of this project is to investigate individual differences in the rate of passage of feed, feed efficiency, microbial flora and methane production in cows with different ability to consume large proportion of roughage.
Our previous studies show that methane production differs between cows with the same intake and that individual differences are greater than the effect of the diet. This variation could make it possible to breed cows with lower methane production and more energy for milk production. However, it is important to identify the reasons for the difference, otherwise there is a risk of selecting cows that produce less methane due to of less digestion of feed. This study plans to use cows in an already funded project where the individual's ability to utilize roughage is studied. We want to collect the data on methane production, microbial composition, passage rate and genetic markers for methane production in order to evaluate the potential for selection of efficient cows.
Syftet med detta projekt är att undersöka individuella skillnader i passagehastighet av foder, foderutnyttjande, mikrobflora och metanproduktion hos kor med olika förmåga att konsumera stor andel grovfoder.
Våra tidigare studier visar att metanproduktionen skiljer mellan kor med samma intag och att de individuella skillnaderna är större än effekten av foderstaten. Denna variation skulle kunna göra det möjligt att avla på kor med lägre metanproduktion och mer energi att utnyttja till mjölkproduktion. Det är dock viktigt att först ta reda på orsakerna till skillnaden, annars finns det risk att man selekterar för kor som producerar mindre metan för att de utnyttjar fodret sämre. Denna studie planerar att nyttja kor i ett redan finansierat projekt där individens förmåga att utnyttja grovfoder studeras. Vi vill samla data om metanproduktion, mikrobiell sammansättning, passagehastighet och genetiska markörer för metanproduktion för att utvärdera möjligheter för selektion av effektivare kor.

Knowledge of disease development in wheat is a prerequisite for good advice on economically and environmentally
adapted control strategies. This project is based on knowledge from a previous SLF project about molecular detection
and spore traps, which showed that the different spore traps catch …

We are facing a protein shift in which a portion of the animal based protein in our diet needs to be replaced by plant proteins to reduce the climate impact from the food sector. Many agricultural by-streams contain high value proteins not used to their full potential. We aim to recover proteins …

Disease and production disturbances in a herd are often silent, and may cause major losses if they remain undetected. Continuous analysis and monitoring of data already recorded at the farm level can improve profitability. This project will develop methods for monitoring trends in production and …

The purpose of the project is to analyse stable cultures in cyberspace in Sweden and Norway. In recent years, questions about the welfare of horses have been debated in social media and norms for horse-keeping are created on Internet. In this project, these norms are conceptualised as stable …

Correct assessment of hind limb lameness is a challenge, also for most experienced vets. This causes incorrect diagnoses and faulty treatment interventions which lead to unnecessary suffering for the horses and an unnecessary financial burden for owners and insurance companies. The aim of this …

Icelandic horses are increasingly popular in Sweden and Norway. Their strength lies in their unique gaits, however, in lame horses this trait becomes a weakness. Evaluating not only lameness but also the leg of origin for lameness in any gait other than trot is exceptionally challenging. Today, we …
