PERDIGAO, A.  y  ROQUETE, C.. Charolais and BBB bulls at suckling cow herds. Rev. de Ciências Agrárias [online]. 2007, vol.30, n.1, pp.190-197. ISSN 0871-018X.

The Belgian Blue White (BBB), is a beef cattle breed for terminal crossings that have come, through exposition in fairs, trying to convince the national cattleman about its interest. We are as it is logical before a marketing effect! This work intends to demonstrate, as contribution, what really happens when we use BBB bulls (by artificial insemination), still compared with the bulls of Charolesa breed, in terms of reproductive and productive reply. The increment of weaned weight through BBB was interesting (+15%), as well as almost the inexistence of distocia (all mature cows). However, about the artificial insemination, as a livestock instrument, we have to point out the increment of the difficulties of management that can discourage the producers, for the use of the BBB breed.
