ABSTRACT


Germán Klee G.1 e Ignacio Ruiz N.2
 

During 2 years (1971-73) an experiment was carried out to develop a beef production system based on 7 month old European X American Holstein autumn-born calves. A ladino white clover-perennial ryegrass mixture, mainly for grazing, and red clover alone, mainly for hay, were utilized. Likewise, some stilbestrol treatments were imposed to the steers during the different grazing periods.
