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.
