Feeding calves according to their needs in the first few weeks has a greater influence on performance than breeding. During approx. the first 40 days of life the foundations for fully exploiting the calves’ genetic potential are laid. Metabolic programming also takes place during this phase and has a lifelong effect. The first 40 days of life are crucial because the growth of tissue and organs takes place as a result of cell division. After that, it is no longer the number of cells that grows, but only their volume. With the 40FIT feeding plan in conjunction with many hardware and software products, Förster-Technik provides optimum support for calf growth during this phase.
