ABSTRACT
The use of Mulato (Brachiaria
mulato), a new improved grass that has currently been
introduced in Indonesia, in goats feeding
system is lacking. This study aimed to examine the
effects of supplementation of different legume leaves on feed intake, digestibility and daily liveweight gain of goats given Mulato grass as the basal diet. Twenty four male Kacang
goats of approximately seven months old with initial body
weight of 15.85 ± 0.56 (SE) kg were
used. The experiment was a randomized
block design with four treatments, and each treatment was
replicated six times. The goats were randomly distributed
into six groups according to their initial body weight rank. The dietary treatments tested
were: T1: Mulato grass ad libitum (M), T2: M + Desmantus pernambucanus leaves (1.5% of body weight/day) (MD), T3: M + Gliricidia sepium leaves (1.5% of body weight/day) (MG), and T4: M + Leucaena leucocephala leaves (1.5% of body weight/day) (ML). The animals were
confined in individual metabolic crates during the study, which consisted of two weeks adaptation period
and eight weeks measurement period.
Parameters measured were feed dry matter intake (DMI), dry matter digestibility (DMD), estimated
metabolisable energy intake
(MEI), metabolisable energy retention (MER) and daily liveweight
gain (DLG). Results showed that supplementation
with different legume leaves to the goats receiving Mulato grass
significantly increased (P < 0.05) total DMI, DMD, MEI, MER and DLG of the animals. Total
DMI for goats treated with T1, T2, T3 and T4 were 3.61%, 3.85%, 3.98% and 3.89% of body weight/day, respectively. Feed DMD for the
four treatments were 57.68%, 63.66%, 65.74% and 64.81% for T1, T2, T3 and T4, respectively. DLG were 51.98, 69.84, 84.92 and 75.40 g/day for goats treated with T1, T2, T3 and T4, respectively. It was concluded that supplementation
of legume leaves to Kacang goats fed Mulato grass
significantly increased feed DMI, DMD and the animals’ DLG, but there were no significant differeces among the legume leaves as feed supplements.
