Abstrak: Increased of
ruminants energy intake can be conducted by increasing the energy density of
feed by using fat (oil). Protein intake can be enhanced by increasing of
protected protein that escapes degradation by rumen microbes. The Aim of this
research was to evaluate protected of feed supplement based on dry matter
digestibility (KcBK), organic matter digestibility (KcBO) in vitro in the rumen
and post-rumen. Protected feed supplement was produced from sardine fish oil
and hydrolyzed blood , throught two protection methodes. It was saponification
and microencapsulation. This research uses a completely randomized design with
3 treatments (feed supplements protected, soybean meal and pangola grass),
which each treatment was repeated 5 times. The results in the first step
(rumen) of the protected feed supplement showed that has dry matter
digestibility 24.46% and organic matter digestibility 57.17%, soybean meal has
dry matter digestibility 75.20% and organic matter digestibility 75.66%, and
pangola grass has dry matter digestibility 50 , 81% and organic matter
digestibility 59.21%. In the second step (post rumen) the digestibility of
protected feed supplement has dry matter digestibility 69.04% and organic
matter digestibility 66.71 72.76%, soybean meal has dry matter digestibility
90.38% and organic matter digestibility 88.23%, and the grass pangola have KcBK
63.24% and KcBO 59.21%. The results could be concluded that in the rumen
protected feed supplementation is the most microbial degradation resistant
compared the other and it can be degraded and digested in the abomasum to the
small intestine.
