Poultry have a strong motivation for foraging and spend most of the day pecking and searching for food. In commercial conditions, the birds are fed a pellet diet, which is consumed very quickly. Consequently, hens spend a large part of the day engaging in abnormal non-food related pecking activities such as feather pecking. Therefore, the aim of this project is to test the use of Black Soldier Fly larvae (Hermetia illucens) as a novel environmental enrichment to promote foraging behaviour and reduce feather pecking in laying hens. A secondary aim is to use larvae, which are rich in protein and are grown in Sweden using local blue mussel by-products, as an alternative food source for laying hens. The use of larvae in poultry feed has, therefore, the potential to improve the welfare of laying hens and promote the sustainability of the Swedish egg industry by reducing the use of imported soy and introducing a circular system, regaining lost nutrients back into the food production loop.
I naturen använder fjäderfän stor del av sin vakna tid till picka och krafsa för att hitta ätbara frön och levande insekter. I kommersiell äggproduktion ges hönan ett pelleterat foder i ett tråg och kan snabbt stilla sin hunger. Därmed finns mycket tid över till att utföra andra beteenden, vilket kan leda till att oönskade beteenden som t.ex. fjäderplockning uppkommer. Syftet med detta projekt är att undersöka om levande larver av svarta soldatflugan (Hermetia illucens) kan ge möjlighet att tillfredställa hönans naturliga motivation att söka föda och därigenom minska förekomsten av fjäderplockning. Syftet är även att använda lokalt odlade blåmusslor som substrat för larverna och på så sätt i ett kretslopp återföra näring från sjöar och hav till lantbruket. Med larver, som odlats på blåmusslor, som proteinkälla i hönsfodret kan hönornas välfärd förbättras, övergödningen av sjöar och hav minskas och behovet av soja reduceras, vilket leder till ökad hållbarhet i svensk äggproduktion.

Healthy seeds are a prerequisite for sustainable food systems. The seed-borne plant disease, common bunt (CB) in wheat, caused by the fungi Tilletia tritici and T. laevis, is a major problem in agriculture. Efficient chemical seed treatments exist, but it is often difficult to keep up with autumn …

A sustainable use of phosphorus fertilizers has engaged a large number of researchers, especially how to measure
the soil content of available phosphorus. However, the development of results to useful methods for agriculture has
not been a priority. The recommendations are based on extraction with …

Fruit tree canker, caused by the fungus Neonectria ditissima, has become a threat for Swedish apple production. No efficient protective measures are available and no complete genetic resistance is known in apple. However, apple genotypes differ in the level of partial resistance which must be fully …

Cereal production is limited by many different factors. Leaf diseases are often well known, while diseases on roots are more difficult to identify. Root diseases are often caused by oomycetes, fungus-like microorganisms that live for years in soil and on old root debris, parasitizing the roots of …

The rollback of insecticides exposes Swedish horticulture to a multitude of pests. Targeted and sustainable innovations are sorely needed. Here we target several pests of fruits, onion, cabbage, beans and salad and aim to develop 1) species-selective lures using a novel olfactomics platform, 2) use …

Spread of barnyard grass, growing in southern Sweden has accelerated during the last decade and is rapidly moving northwards. No herbicide-resistant populations have been reported from Sweden thus far, but it is only a matter of time before barnyard grass will develop herbicide resistance in …

This interdisciplinary project examines how Swedish dairy farmers, given different types of policy instruments, are affected by the ongoing structural transformation in the primary production. The study will improve our understanding about how the ongoing structural change affects profitability in …

We need to remediate the capacity of agricultural landscapes to retain water, nutrients and sediments to make them
more resilient to the increasing frequency of flooding, drought and pollution expected with the climate change. It can
be done by remediating existing narrow ditches into ditches with …

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 …

Colibacillosis is a common disease in poultry and includes both local and systemic infections. Increased knowledge is necessary for development of effective methods to prevent disease, such as improved management routines, modification of environment, and vaccine development. The first study (WP1) …
