Different feed mixtures with reduced dietary energy level (< 12 MJ AME/kg) and reduced content of essential amino acids were investigated. In case of reduction a constant ratio of amino acids to energy was considered. Under the future European law for organic products all raw materials used for the feed were of organic origin. The feed consumption of the different feeding groups ran conversely proportional to the diets energy level. The obtained fattening performance and carcass yield reached a high level under the circumstances of organic production.
