The fatty acid and sterol compositions of different parts of Malagasy zebu (Bos indicus) were evaluated. Investigation by gas liquid chromatography using Carbowax 20 M revealed 35 fatty acids, mainly palmitic (24‐27%), stearic (13‐24%), and oleic (25‐37%) acids. Odd‐numbered, iso and anteiso fatty acids were also detected. Small differences in composition were observed between the hump and the kidney fats of B. indicus. Comparison between industrial tallow of B. indicus and B. taurus revealed slight differences in the stearic/ oleic acid ratio (0.83 and 0.46, respectively). An OV 17 column was used to separate 9 sterols, mainly cholesterol (89‐98%). β ‐Sitosterol was also found at lower concentrations in all the samples.
