Description

Two experiments were conducted to evaluate the value of leucaena (Leucaena leucocephala) as a supplement to low quality roughage of spear grass (Heteropogon contortus) hay fed to goats and sheep. In the first experiment using goats, a basal diet of spear grass (SG) was supplemented with urea (SG + U) or Jeucaena (SG + L). Daily organic matter (OM) intake was significantly greater on the SG + L diet (38 g/kg BW0•75) than on the SG or SG + U diets (21 and 23 g/kg BW° 75 respectively). Non ammonia nitrogen (NAN) flowing from the abomasum was also greater on the SG + L diet (4.9 g/day) than on the SG or SG + U diets (2.4 and 2.8 g/day respectively). In the second experiment using sheep, a basal diet or spear grass with urea and minerals (SG + U/M) was supplemented with leucaena in the diet (SG + U/M + L) or with casein infused into the abomasum (SG + U/M + C). Daily OM intake from Jeucaena supplement (38 g/kg BW0•75) and casein infusion (39 g/kg BW0•75) were both significantly higher than from the basal diet (29 g/kg BW0•75). The NAN flowing from the abomasum with Jeucaena supplement (11.1 g.day) and casein infusion (13.4 g/day) were also both significantly higher than from the basal diet (5.1 g/day). It is suggested that the enhanced feed intake from leucaena supplementation in both experiments was associated with an improved flow of amino acids into the intestines.
