In vitro digestibility study was conducted to determine the effectsof supplementing fractionated Refined,Bleached and Deodorized Palm Stearin(RBDPST) on ruminal digestion. Fractionated RBDPST was soaked in incubation medium consisting of distilled water, buffer solution, trace element solution, micro and macro mineral solution, as well as rumen liquor that was collected from slaughtered cattle. This experiment was conducted at 39°C with an incubation period of 24 hours. Dried napier grass was used as control treatment. Gas producedwas recorded and collected to measure the methane gas produced. Methane gas produced from fractionated RBDPST was found to be relatively lower than control. This indicates that fractionated RBDPST had the ability to function as rumen bypass fat as it was not fully digested in the rumen.

Refined, Bleached and Deodorized Palm Stearin (RBDPS) is a solid fraction obtained from Refined, Bleached and Deodorized Palm Oil after fractionation by crystallization at controlled temperature. Fractionated RBDPS was found to be enriched with C16 fatty acids,
lacking in trans fat and has a high melting point. The fractionated RBDPS produced had an iodine value of 13.1 gI2/100g, C16 content of 79.7% and melting point 60°C .These characteristics indicate fractionated RBDPS has potential as a rumen bypass fat as well as providing desirable carbon chain composition for good milk characteristics.
