30 individually fed Creole or Creole x Friesian bulls of 80 to 300 kg live weight and aged 1 to 2 years were
used to compare 5 treatments in a trial lasting 14 weeks. Treatments 1 to 3 involved supplementing
molasses containing 3% urea given ad libitum with fresh Leucaena leucocephala at 2%, 3.5% or 4.6%
(ad libitum)of live weight daily. Treatments 4 and 5 were designed to provide protein and crude fibre
intakes equal to treatments 1 and 3 respectively using groundnut cake and Ischaemum aristatum. All
animals received mineral mixture (50% Sodium Chloride and 50% Dicalcium Phosphate) ad libitum.
Intake of groundnut cake was lower than planned no that protein intakes of treatments 1 and 5 were
equal. Average growth rates for treatments 1 to 5 were 0.791, 0.737, 0.848, 0.595 and 0.744 kg/d. It is
concluded that the optimum feeding rate of fresh Leucaena for maximising gain n and molasses intake is
2.0% of live weight daily and that it appears to be a satisfactory protein and fibre source.
