Einfluß der Preisentwicklung von Einzelfuttermitteln in den Jahren 2005, 2007 und 2008 auf den Preis von 100% Bio- Legehennen-Alleinfutter

Summary

Four layer-mash rations based on 100% agricultural feedstuffs of organic origin and
with different levels of energy content were tested at the University of Kassel some
years ago. Now it is to investigate the influence of different parts of the feedstuffs in
the composition of the rations on the cost of the 100% layer-mash in three years with
different costs for the feedstuffs. It is obvious to see, that the price of protein sources
like soy-products or some oil cakes (sesame) and the grain legumes ascended about
100% from 2005 to 2008. Layer mash with the highest energy level is in all years the
most expensive variant. The facts due to concern, that regarding to actual price trends
of organic protein sources, it is favourable to reduce energy content of layer mash,
leaving static tradition and act sparingly with organic feedstuff resources.
