Summary

Production of organic beef from young cattle is not very developed in Denmark, in spite of a well-established organic dairy production with male off-spring. These calves are sold to conventional production, because of low performance in organic production systems. The purpose of this study was to test a concept for production of organic beef based on crossbred animals from dairy cows sired with a beef breed. The experiment included a comparison between spring-born pure-bred Holstein bulls (HB), crossbred Limousin x Holstein bulls (CB) and heifers (CH), 15 of each group. After weaning the calves were raised outdoor on pasture the 1st summer and indoor on a low energy grass-haylage ration over winter followed by pasture the 2nd summer and slaughter at a fixed age of 16.9 mo. CB showed an improved daily gain, EUROP conformation, but not fatness compared with HB, which was inferior compared with the CH. A sensory evaluation showed more intense aroma and taste characteristics of the loin from HB compared with the other groups, whereas the tenderness of the loin and round from both HB and CB were inferior compared with CH, and is expected to be too low to fulfil consumer expectations of tender beef.
