The Calvex Company’s Passion – Work with Calves. The first two months of a calf’s life is the most important period in which the difference between success and failure in the future is determined. Therefore, it is precisely in this period of time that it is necessary to lay the basis for future incomes. Calvex is trying every day to learn more about how to grow calves. They do this partly due to the acquisition of the latest scientific technology and knowledge in this area. At the Calvex Gaarden Demonstration Farm they produce their own beef, Calvex constantly tests various innovations and innovations in management – all to find a way to success.
