Summary

False flax (Camelina sativa) is a very beneficial oil seed in organic plant production. Its added value could be enhanced by using the oil cake in animal nutrition, which is very interesting for organic feeding due to the demand of farm grown crude protein and energy delivering plants. But European feed law does not allow such an use. An application for an amendment of the ordinance only seems promising, if it is possible to make a scientifically based proposal concerning the unproblematic amount of Camelina oil cake in the diet. Therefore in an organic feeding trial with a total of 192 broilers the effects of different amounts of Camelina oil cake (0%, 2.5%, 5% and 5% heat and pressure treated) in the diet concerning performance, carcass and meat quality were tested. The substitution of Camelina oil cake against soy cake till 5% caused inconsistent results concerning performance. Treated oil cake significantly caused poor performance and enlarged thyroid glands and livers. Carcass, meat, and fat quality remained unaffected. But anyway, a recommendation concerning the rea-sonable amount of Camelina oil cake in a broiler diet based on this single trial seems not feasible. Therefore further research has to be done.
