Hva gjør vi med slakteklare verpehøns?

Summary

Spent laying hens are sometimes killed by gas and incinerated, due to a lack of rendering plants to produce meat and bone meal. An alternative could be to utilize the hens for fertilization purpose. This study was conducted to explore the decomposition of chopped complete hens in soil, and to measure the fertilization effect of residues after hydrolysation of grinded, slaughtered hens. Results are shown in this paper.
