Ketahanan Asam Lemak Tidak Jenuh dalam Crude Palm Oil Terproteksi terhadap Aktivitas Mikrob Rumen Domba in Vitro
Abstract: The experiment was
aimed to study the composition of unsaturated fatty acid, fermentation
parameter and microbial activity in the rumen-buffer mixture when protected CPO
with casein and formaldehyde was incubated in the in vitro fermentation. CPO
and milk powder (1:2) were mixed, added technical formaldehyde 0%, 1%, 2%, and
3% by weight of blend, mixed again to form CCPO. The amount of 0% (0 mg), 1.5%
(4.5 mg), 3% (9 mg), 4.5% (13.5 mg) and 6% (18 mg) CCPO was inserted into
fermenter bottles containing napier grass and rice bran (60:40), was tested in
vitro. The data were analyzed by completely randomized design with factorial
pattern 4 x 5 (level of formaldehyde as factor A and level of CPO as factor B).
The different of treatments were tested by Duncan's new multiple range
test. Result shows that the increase of
formaldehyde level could increase unsaturated fatty acids content, CMC-ase
activity, microbial protein and number of protozoa, but decreased NH3, VFA, and
pH of rumen fluid. The increase of CPO level also increased fatty acid
composition and microbial protein, but decreased NH3, VFA, and pH, CMC-ase
activity and number of protozoa in rumen fluid. It can be concluded that
encapsulated CPO with formaldehyde increased unsaturated fatty acid composition
and microbial activity, but decreased fermentation parameters.
