Auswirkungen der Fütterung auf die Qualität von Mastlämmern : Hat die Fütterung im ökologischen Landbau Auswirkungen auf die Fleisch- und Fettqualität?

In 2000 to 2004 four experiments were performed with finishing lambs fed feeds produced under organic farming conditions. The protein sources were rape seed and other grain legumes. Conventional fed lambs were fed soya meal as protein source. Feeding of soya meal is not allowed under organic production conditions. We investigated the effect of different diets on the growth, meat and fat quality of finishing lambs. The growth of the lambs was better under conventional feeding conditions compared to organic farming. The meat quality was not different between both feeding systems. The influence on fat quality were related to the fatty acid composition of the feed. From the nutritional point of view no advantage for organic farming of lambs was measured according to the fat composition.
