Three groups of dairy cattle were compared under different grazing
managements viz. strip-grazed on pure ruzi grass (Brachiaria
ruziziensis), strip-grazed on mixed pasture between ruzi and leucaena
(Luecaena luecocephala) and strip-grazed on pure ruzi and
supplemented with lablab (Lablab purpureus). The results showed
that the animals that received the legumes through supplementary or
mixed with the grass produced higher in daily milk yield (13.63 and
13.26 kg/cow) and fat percentage (4.7 and 4.5) than that of the pure
grass alone (12.00 kg/cow for milk yield and 4.2 % for fat). This
advantage was due to the greater crude protein levels compared with
that of pure grass alone. It is concluded that growing tree legumes
with grass or sowing of pure herbaceous legumes can be
recommended as dairy cattle pasture in Thailand.
