In this project feather meal from chicken feathers was hydrolysed to increase the digestibility. The chemical content of the feather meal was examined as well as amino acids composition. The Icelandic feather meal was also compared to results of researches conducted elsewhere on feather meal. Feather meal has an 80% protein content and its digestibility is comparable to fish meal. Feather meal has been used for a long time in feed in North and South America and has in recent years been pushing itself as a cheap protein source for farming animals in Europe.
