The fatty acid compositions of oocytes, oviductal and uterine fluids of rabbit were analyzed by gas chromatography and were compared with those of blood serum and body fat. Myristic (C14:0), palmitic (C16:0), palmitoleic (C16:1), stearic (C18:0), oleic (C18:1), linoleic (C 18:2) and linolenic (C18:3) acids were identified as the common fatty acid constituents in the objects. The fatty acid constituents of reproductive tracts fluids seemed to be quite similar to those of blood serum and body fat. In oocytes and different reproductive fluids, oleic acid composition was the highest (26.59 to 32.79%), followed by palmitic (21.83 to 25.8%), and linoleic (18.33 to 23.55%) acid. Myristic, palmitoleic, stearic and linolenic acid compositions were always low in oviductal (2.12 to 7.91%) and uterine (2.05 to 10.48%) fluids. On the other hand, myristic and stearic acid were moderate (16.66 and 14.17%, respectively) but palmitoleic and linolenic acid were not detected in oocytes. Palmitic, stearic, oleic and linoleic acids comprised more than 80% (82.24 to 86.43%) of the total fatty acid fraction in all samples analyzed.
