title: [The optimization of group size for fattening rabbits in group housing on grids made of artificial material].
abstract: ZIKA-fattening rabbits in groups of 4, 8, 16, 32 and 64 animals (5 rabbits/m2) have been proved in 6 repetitions with all together 144 animals during the fattening period of nine weeks in regard to their fattening performance, health and behaviour. The aim was to find an optimal group size for fattening rabbits with respect to animal welfare. The results show, that fattening performance and health of the rabbits have not been influenced remarkably by group size, whereas behaviour was different in so far, as the rabbits in groups of 16 showed a greater percentage of relaxed positions as well as a remarkable smaller percentage of aggressive behaviour. Therefore the group with 16 fattening rabbits is that, which can be advised for the fattening of rabbits in the Hohenheimer group housing.
