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

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. The rations had different parts of inland feedstuffs (grain, grain legumes, grass meal) and components from foreign countries (soybean, sesame cake). High energy compositions had a larger part (ca.28%) of foreign feedstuffs. The part of foreign components could be reduced about 10% by decreasing energy content. Ascending costs for the feedstuffs resulted in greater increase of costs for those mixtures with greater amounts of foreign feedstuffs. It would be necessary to search for more solutions in order to strengthen inland feedstuff production and regional organic energy consume.
