Abstract
3 group feeding experiments were carried out with the glycopeptide antibiotic avoparcin. Avoparcin was added to salt licks (2.5 g per kg lick stone) and offered to 30 (experiment I), 80 (experiment II), or 20 (experiment III) growing cattle ad libitum over 210, 122, or 281 days. Control animals consumed unsupplemented lick stones. The avoparcin intake amounted to 60 (experiment I), 145 (experiment II), and 100 mg (experiment III) per cattle per day. The daily weight gain increased from 750 to 808 (experiment I), 553 to 649 (experiment II), and from 812 to 822 g per animal per day (experiment III) when avoparcin was added. Avoparcin is a safe feed additive and should be supplemented to various lick stones to improve ruminant performances under tropical rangeland conditions. 15 to 30 mg avoparcin per kg dry matter intake are recommended.
