    The aim of this project is to determine the optimal rearing intensity for calves and heifers for the cattle breeds kept in Austria.

    This means that, on the one hand, a lower first calving age is aimed for compared to previous practices in order to reduce the very high rearing costs and thus improve the economic efficiency of milk production. On the other hand, the disadvantages of too intensive breeding should be avoided and in this way the milk production capacity of the cows on the farm should be fully exploited. The most important thing is not to overdo the intensity in the critical phase of udder development (disadvantages for later milk production!) and to achieve higher animal development in the remaining phases, which leads to earlier calving and therefore lower costs. This is intended to directly improve the economic efficiency of milk production on farms.

    This project is carried out in cooperation with the following agricultural colleges and HBLAs:
