Abstract
We fed broiler breeder hens on a diet according to the standard without and with a straw portion of 19% to test the influence of fibre on the Fe, Cu, Mn, Zn and Cd status. The amount of concentrated feed per animal and day was the same. The trial lasted 4 months. The high straw portion did not influence laying performance, eggshell stability, and the health of animals. The Fe, Zn, Mn, Cu and Cd contents were not significantly influenced in some reference organs. It can be deduced from these investigations that a very high fibre content in the ration does not influence the mineral status of laying hens in the long run.
