“…Fatty acid profile and proximate composition of meat vary can be influenced by breed, feed, age and sex of animal [4] [5]. Age of animal and breed in particular influence the concentration of MUFA in beef by affecting Stearoyl-CoA Desaturase (SCD) gene expression and activity [6].…”

This study was conducted to determine proximate composition and profile of fatty acid of beef from Arsi, Borana and Harar Cattle breeds in Ethiopia. A total of 39 bulls with three age categories were used for the study. The bulls were purchased from mixed crop livestock system (Arsi and Harar cattle breeds) and Ranch (Borana cattle breed). Complete randomized design was used for the study. Longissimus dorsi muscle was used to evaluate proximate composition and profile of fatty acid. The result of the study indicated that mean of percentage of dry matter, ash, crude fat and crude protein were ranging 22. 43 -24.26, 0.32 -1.28, 4.32 -7.88, 17.21 -22.76, respectively. At age younger than 3 years, Harar bulls contain more crude fat compared to Arsi bulls while the vice versa was true for crude protein. The concentration of polyunsaturated fatty acid (PUFA) was higher than saturated fatty acid (SFA) in the three breeds studied across all age categories. However, significantly higher (P < 0.01) PUFA and lowest (P < 0.05) SFA found in Harar breed whereas the opposite hold true for Arsi bulls. Ratio of n-6: n-3 in the muscle of bulls under the study was ranged from 2.10 to 2.57. Concentration of PUFA and MUF in muscle of the three breeds were significantly affected (P < 0.05) by age. From the study it was concluded that Arsi, Boran and Harar bulls under the three age categories contained more than 3% minimum crude fat that is required to insure palatability of the beef. The higher concentration of PUFA over SFA in all breeds across age categories indicated that the meat from these cattle breeds has less risk hazard to human health.
