Heat stress is expected to be of major concern in Swedish animal production systems in the future. The air temperatures in parts of Sweden are expected to correspond to today's temperatures in southern Europe, where livestock experience heat stress today. Excessive thermal load affects the welfare and health of pigs negatively. Confined pigs have limited physiological and behavioural abilities to loose heat. In an effort to loose heat during warmer periods pigs often choose to lay on the cooler slatted floor resulting in pen fouling, increased workload, disturbance of the pigs' resting behaviour and increased agonistic behaviours. Pen fouling also has negative impacts on the air quality (ammonia, airborne bacteria and respirable particles). Floor cooling in pens for fattening pigs has the potential to enhance the thermal and gaseous environment in the fattening pig barns resulting in improved pig welfare, performance and health as well as the working environment.
Värmestress förväntas bli ett stort problem inom svensk animalieproduktion i framtiden. Lufttemperaturerna i delar av Sverige förväntas motsvara dagens temperaturer i södra Europa där produktionsdjur upplever värmestress idag. Bl.a. påverkar alltför hög värmebelastning grisars välfärd och hälsa negativt. Inhysta grisar har begränsade fysiologiska och beteendemässiga möjligheter att göra sig av med överskottsvärme. Redan idag väljer ofta grisarna att lägga sig på det svalare spaltgolvet under varma perioder. Detta leder till nedsmutsning av boxarna, ökad arbetsbelastning, störning av grisarnas vilobeteende och ökade agonistiska beteenden. Smutsiga boxgolv har även en negativ inverkan på stallmiljön som påverkar grisarnas hälsa samt arbetsmiljön negativt. Golvkylning i boxar till slaktsvin har potential att förbättra den termiska och gasformiga miljön i slaktsvinsavdelningar som i sin tur leder till förbättrad djurvälfärd, produktion och hälsa likväl som förbättrad arbetsmiljö.

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 …

About 200 dairy farms in Sweden use recycled manure solids (RMS) as bedding material and the number is increasing. Advantages is low price, reliable availability and good cow comfort. The main disadvantage is the risk of increased bacterial growth on the lying area affecting especially udder health …

The project aims are to use the information about cow's DNA profile to estimate the severity of fertility problems caused by specific genetic defects in the Swedish Red (SRB) and Holstein dairy breeds, and to estimate the economic impact of pregnancy losses caused by these genetic defects. Our goal …

Every year, about 500,000 claw trimmings are recorded in Swedish dairy cattle. The aim of claw trimming is to detect, treat and prevent painful claw lesions. However, the claw trimming in itself can be harmful and cause claw lesions if it is not done correctly. The aim of the project is to develop …

Harness racing is hazardous as horses are running in close proximity at high speeds. Thus, an effective communication between driver and jockey-horse via rein signals to the bit is essential for safety reasons and horse welfare. However, scientific studies on rein tension in Standardbred trotters …

Just going to the bathroom is contributing to algae blooms and climate change. Sweden alone releases roughly 15400 tonnes of N and 240 tonnes of P into lakes, rivers and seas, through municipal wastewater (including after treatment). Urine contains 80% of the plant nutrients found in wastewater and …
