Abstract

Growth performance and seminal attributes of bull calves fed Leucaena or Desmanthus with limited concen-trate mixture were measured over six months. Growth rate was significantly higher in animals fed Leucaena (735 g day-1) than those fed Desmanthus (543 g day-1). The digestibility coefficients for dry matter, organic matter, crude protein and energy were higher for Leucaena than for Desmanthus. The concentration of sperm was significantly higher in Jersey bulls than in Holstein bulls. There were no breed or treatment differences in ejaculate volume, motility, fructolysis index, Ca, Mg, and P contents in the semen. No toxicity symptoms were observed in the animals fed on Leucaena.
