Summary: | This research was aimed to observe the effect of sereh leaves
(Cymbopogon citratus) addition as essential oil (EO) source in diet
towards rumen microbes population and ruminal nutrient digestibility in
vitro. Essential oil were added 0, 25, 50,75, and 100 mg/l. Substrates for in
vitro fermentation contained crude protein 9.94% and total digestible
nutrient 88.5%. The treatment�s had 3 replication. Data collected were
rumen microbes population, dry matter digestibility (DMD), organic matter
digestibility (OMD), crude protein digestibility (CPD), and crude fiber
digestibility (CFD). The collected data was analyzed by one way variance
analysis. The difference between mean was tested by Duncan�s new
Multiple Range Test (DMRT). The result showed the addition of sereh
leaves equal to EO level as much as 25, 50, 75, and 100 mg/l decreased
rumen microbes population as much as 69.19%, 79.29%, 86.36%, and
95.96% (P<0.01) respectively. Crude protein digestibility increased
(P<0.01) as much as 17.64% in fermentation with EO level as much as 25
mg/l. The supplementation of sereh leaves at EO level as much as 50 mg/l
and 100 mg/l decreased CPD (P<0.01) i.e. 2.52% and 29,65%
respectively. Whereas, the addition of sereh leaves at EO level 50, 75,
and 100 mg/l decreased OMD 9.71%, 9,14%, and 10.79% towards the
control and decreased DMD (P<0.01) as much as 7.54%, 15.90%,
14.75%, 18.12% with addition of sereh leaves equal to EO level 25, 50,
75, and 100.mg/l in diet. Supplementation EO in diet didn�t affect CFD
significantly. From this research, it could be concluded that addition of
sereh leaves as source of EO in diet is at level 25 mg/l because it didn�t
affect the CFD and OMD.
