| 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... |

| 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... |
