Abstract

<abstract abstract-type="main"> <title>Abstract</title> <p>The study appraised the effects of Carotino oil on <italic>in vitro</italic> rumen fermentation, gas production, metabolism and apparent biohydrogenation of oleic, linoleic and linolenic acids. Carotino oil was added to a basal diet (50% concentrate and 50% oil palm frond) at the rate of 0, 2, 4, 6 and 8% dry matter of the diet. Rumen inoculum was obtained from three fistulated Boer bucks and incubated with 200 mg of each treatment for 24 h at 39°C. Gas production, fermentation kinetics, <italic>in vitro</italic> organic matter digestibility (IVOMD), volatile fatty acids (VFA), <italic>in vitro</italic> dry matter digestibility (IVDMD), metabolizable energy and free fatty acids were determined. Carotino oil did not affect (<italic>P</italic> > 0.05) gas production, metabolizable energy, pH, IVOMD, IVDMD, methane, total and individual VFAs. However, Carotino oil decreased (<italic>P</italic> < 0.05) the biohydrogenation of linoleic and linolenic acids but enhanced (<italic>P</italic> < 0.05) the biohydrogenation of oleic acid. After 24 h incubation, the concentrations of stearic, palmitic, pentadecanoic, myristic, myristoleic and lauric acids decreased (<italic>P</italic> < 0.05) while the concentration of linolenic, linoleic, oleic and transvaccenic acids and conjugated linoleic acid (CLAc9t11) increased (<italic>P</italic> < 0.05) with increasing levels of Carotino oil. Carotino oil seems to enhance the accumulation of beneficial unsaturated fatty acids without disrupting rumen fermentation.</p> </abstract>
