Fatty acid profile in milk of Busha, Cika and Simmental breed

In this research the fatty acid profile in Busha’s, Cika’s and Simmental’s milk was investigated. For research purpose 42 milk samples were collected during July (Busha, n = 15; Cika, n = 17 and Simmental, n = 10). All cows were held in outdoor system. Busha’s milk had significantly (P < 0.05) lower content of SFA, as well as significantly (P < 0.05) higher content of MUFA and PUFA in regard to Cika’s and Simmental’s milk. Lower SFA/MUFA, SFA/PUFA and n-6/n-3 PUFA ratios, but higher content of n-6 PUFA in Busha’s milk in regard to Cika’s and Simmental’s milk was also determined. Statistically significant differences were not found (P > 0.05) in cows milk in regard to n-3 PUFA content. However, in Busha’s milk higher content of DHA (P < 0.05) in comparison to Cika’s and Simmental’s milk was found. Cika’s milk had statistically significantly higher content (P < 0.05) of CLA than Busha’s milk. Significant differences in fatty acid profile between Busha’s milk and milk of Cika and Simmental breed were determined, but for assessment of effects of system of keeping and keeping altitude, lactation stage and parity, as well as of other possible effects on milk fatty acid profile, further investigation is needed.
