ABSTRACT
The use of leguminous trees to supply livestock with a source of nitrogen and protein during the dry season has recently increased in the tropics and sub-tropics. Of the numerous legumes available, one of them, Leucaena (L. glauca), has been given pride of place as a versatile legume adapted to areas with an average annual rainfall varying from 600-1800 mm (National Academy of Sciences, 1977). The meal obtained by grinding the dried leaves of the Leucaena tree has a protein content of nearly 30%. Therefore, it may be possible to use leucaena leaf meal as a means of meeting the amino acid requirements of pigs fed in the tropics.
