The objective of this study was to compare the fatty acid and terpene profile of ovine and caprine milk from animals raised under a semi-extensive production system in commercial farms located in Northwest Greece. Regarding fatty acid profile, ovine milk had a higher percentage of conjugated linoleic acid (CLAcis-9, trans-11) as well as higher percentages of both n-6 and n-3 fatty acids in relation to caprine milk. Terpene profile analysis showed a high frequency of appearance for α-pinene, d-limonene, β-pinene in both types of milk. β-Caryophyllene was detected in the majority of the examined ovine and caprine milk samples suggesting that its presence could be used as a potential biomarker of grass feeding. The relative frequency of appearance was higher in caprine milk for the majority of identified terpenes. Ovine milk had better nutritional value in comparison to caprine milk that had an enriched terpene profile than ovine milk.
