Grupo Bertin, one of Brazil's top meat processors, has bought a majority stake in the controlling shareholder of local dairy firm Vigor.

Bertin said earlier this week that it had acquired a 56% stake in Goult Participacoes, which controls 74.7% of Vigor.

The acquisition will give Bertin input into the day-to-day running of Vigor, which produces dairy products, oils and sauces.
