Abstract

The structure of beef production varies very much from one country to another. In some countries the calves reared for beef are mainly purebred dairy or dual- purpose calves. Other countries have adopted large-scale crossbreeding with beef bulls in dairy herds as the basis of beef production. In countries with suckler calves as the main source of calf supply some kind of a hybrid program is mainly adopted.
