Pengaruh Proteksi Aldehid Untuk Meloloskan Poly Unsaturated Fatty Acid Pada Menir Kedelai dan Minyak Ikan Lemuru Secara In Vitro
Abstrak: This research was
aims to determine the effect of formaldehyde using as a protective material in
the soy groats and lemuru fish oil mixtured to escape of the protein and poly
unsaturated fatty acid (PUFA) by in vitro. The rumen fluid was derived from
donor of the Ongole crosbred fistulated as much as 3 heads. The experimental
design used completely randomized design factorial 2x3 pattern consists of two
factors:the first factor (soybean groats:lemuru fish oil in the ratio 2:1 and
4:1) and the second factor (the use of formaldehyde at levels of 0%, 2% and 4%
base on the dry matter) and was repeated 5 times. The parameters are consist of
the nutrient content, the substrates soybean groats and lemuru fish oil the
rumen fluid fermented PUFA content by in vitro. Results of the study are levels
of protein, fatty acids oleic, linoleic
and arachidonic much available on soybean groats:lemuru fish oil protected
formaldehyde at levels of 2% and 4%. The difference between the ratio of
soybean groats with lemuru fish oil had no significant (P≥0,05) but
significantly different at different levels of formaldehyde (P≤0,05). The
conclusion are formaldehyde content of 37% with a level of 2% can be used for
protection the soybean groats and lemuru fish oil with a ratio of 4:1 and is
able to provide protein as well PUFA.
