| Summary: | This study was conducted to obtain the effects of calcium hydroxide and
moisture content level on palm leaves treated on its chemical composition and in
vitro digestibility. Ca(OH)2 level (w/w) were added in DM basis in 0%, 3%, and
6%. Moisture content are used in 40%, 50%, and 60%. Each treatments consist of
3 replications. After treatment, oil palm leaves were placed in polyethylene plastic
bag and stored for 21 days. Data were analyzed by variance (Analysis of
Variance) in 3 x 3 factorial arrangement and continued with Duncan�s multiple
range test if there were differences among treatments. Result showed the DM,
OM, CP, CF, EE, NFE, NDF, and ADF of palm leaves after treated were 37.89 -
59.52%, 87.83 � 92.96%, 8.32 � 9.84%, 35.91 � 40.63%, 5.98 � 7.47%, 34.66 �
40.06%, 64.74 � 75.39%, and 46.56 � 59.32%, respectively. The IVDMD and
IVOMD of palm leaves were 19.26 � 29.55% and 19.91 � 28.26%. It could be
concluded that each level of Ca(OH)2 and moisture content affected the chemical
composition of palm leaves, but not for its digestibility. Less effectiveness of
Ca(OH)2 as single treatment, low level of Ca(OH)2, and short time treatment
periode caused low effectiveness of Ca(OH)2 treatment on palm leaves. Ca(OH)2
6% with 40% moisture content was given the best results in this study.
