Abstract: The purpose of the study was to examine the fatty acid profiles in longissimus dorsi (LD) of buffalo heifers of breed Murrah (Bubalus bubalis) muscle. It has been subdued to three types of treatment: EH – Heifers with ovarian activity ( with fertile cycle) but empty; HOR – heifers with implantation of growth promoter ( 20 mg of stradiol benzoate and 200 mg of Progesterone); LEA – heifers with 100 spheres of lead which have been inserted into the fallopian tubes through an insemination pipette. The contents of moisture, ash, fat, crude protein and cholesterol were around 76.5%, 1.0%, 1.8%, 20.5% and 40 mg/100g, respectively, to the three types of treatment (EH, HOR and LEA). The main fatty acids detected were palmitic (C16:0), stearic (C18:0), oleic (C 18:1 9) and linoleic (C18:2 6) with concentrations varying from 22.61% (EH) to 25.85% (HOR), 20.53% (HOR) to 24.43% (EH), 35.10% (EH) to 36.65 (LEA), 3.87% (EH) to 4.96 (LEA), respectively. Palmitic (C16:0), stearic (C18:0) and EPA (C20:5 3) concentrations presented significant difference (P<0.05) among the treatments. The buffalo meat resulting from the LEA treatment showed higher concentrations of polyunsaturated (PUFA) and monounsaturated (MUFA) fatty acids and mainly higher concentrations of linoleic (C18:2 6); EPA (C20:5 3) and DHA (C22:6 3).
