Fatty acids synthesized in vitro were estimated in bovine adipose tissue and compared with the fatty acid composition of corresponding tissue. Tissues were taken from outer and inner layers of back fat, perirenal, omental and intermuscular sites of Holstein bullocks weighing 278, 385 and 528 kg. Bovine back fat had a higher percentage of unsaturated fatty acids, 16:1 and 18:1 than the perirenal and omental which had a higher percentage of saturated fatty acids, 14:0, 16:0, 18:0. The percentage of saturated fatty acids was similar to that of the unsaturated fatty acids in the intermuscular adipose tissue. Large bullocks weighing 528 kg had a higher percentage of unsaturated fatty acids than the small and medium sized. Composition of the fatty acids synthesized in vitro was similar to that present in the tissue, except that more 18:0 and less 18:1 were synthesized in comparison to amounts contained in the tissue.
