The aim of the project is to develop tools which can be used for individually adapted lactation lengths based on the biological conditions of the cow. Today a one year calving interval and a short lactation period, is recommended. The recommendations are based on 30 years old information and do not take into account individual variations between cows. In this project 20 large dairy herds will be included. We will gain information from the individual cows in each herd related to milk yield, fertility and health and validate the tools as predictors of cows which benefit from an extended lactation. We will test the tools by selecting primiparous cows based on the developed predictive tools. We will create genomic breeding values which can be used to identify cows which benefit for an extended lactation. We envision that farmers who adopt the concept of individually adapted lactation lengths will experience better health and welfare, fertility and productivity in their herds.
Syftet med projektet är att utveckla verktyg som gör att man individuellt anpassa laktationens längd hos kor beroende på deras biologiska förutsättningar. Rådgivningen i dag förespråkar ett kalvningsintervall på 12 månader. De beräkningar som rådgivningen grundas på är 30 år gamla och förutsättningarna idag är annorlunda. De beräkningarna tar inte hänsyn till de stora variationerna mellan kor avseende ämnesomsättning och mjölkavkastning. Vi att samarbeta med 20 mjölkkobesättningar och studera individanpassade laktationslängder hos förstakalvare i besättningarna. Syftet är att utveckla och verifiera ett koncept för individuellt anpassad laktationslängd baserat på information främst från mjölk. Vi kommer också att skapa genomiska avelsvärden för att identifiera kor som passar för en längre laktation. Resultaten kommer att bidra till en ökad lönsamhet och bättre djurhälsa och fruktsamhet i de besättningar som använder de nya verktygen.

Humus is an important indicator of soil quality and soil organic carbon (SOC) sequestration is a cost-effective measure to reduce the climatic impact of food production systems. The national soil-monitoring program (SMP) show an upward trend in SOC during the past 20 years, mostly attributed to an …

Consumers appreciate onions in all kinds of cooking. Onions can be grown in Sweden with good results. Onions can be stored for a long period. There is a potential to increase the self-sufficiency in onions. To achieve this, a better knowledge of long-term-storage potential indicator factors that …

Acquired equine polyneuropathy (AEP) is a devastating neurologic disease affecting Nordic horses. Characteristic histopathological changes have been shown in the peripheral nerves of horses euthanized due to the disease. These include re- and demyelination as well as hypertrophy of perikaria and …

A few years ago, media reported on a 7 year-old girl who was killed during a riding lesson. The accident evokes questions about children, horses and safety. Children are small and horses big, and the horse is a herd and prey animal whose behaviour is partly controlled by instincts. Today, many …

Soft tissues around the kneecap (patella) as a cause of equine lameness is an area yet to be scientifically investigated but that is often clinically treated with “alternative” methods without an established diagnosis. In human medicine, patellar tendinosis is a common verified diagnosis. …

A cornerstone of the Swedish Food Strategy is trust in Swedish food production. Yet each year Swedish farmers and food processors lose both money and trust due to food fraud, especially for non-Swedish meat relabelled as Swedish. Most fraud remains undetected. A recent analytical development, Rapid …

Cannabinoids have potential to induce analgesia and muscle relaxation which would be beneficial for equine practice. Today there is no drug labelled for veterinary use containing these cannabinoids, but there are some herbal oil products which unofficially have been reported to be used in horses, …

This project aims to modify existing sensor systems for adapted nitrogen fertilization to consider water stress at
supplementary fertilization in cereals. Different approaches to consider sensor data and soil information will be tested
in field trials. Current commercial systems interpret water …
