Abstract

The perennial, trailing legume Calopogonium caeruleum grown with common guinea grass (Panicum maximum), was evaluated under continuous grazing at c 2.5 beasts ha^-1 over three years at Utchee Creek in the wet tropics of Queensland.
C. caeruleum was rarely eaten and by the third year the guinea grass was selectively grazed out and C. caeruleum dominated the pasture. The average daily liveweight gain declined from c 0.5 kg beast^-1 in the first two years to less than 0.2 kg beast^-1 in the third year.
