The objective of this meta-analytical study was to investigate concentrations of milk saturated fatty acids (SFA) including C4, C6, C8, C10, C12, C14, C15, C16, C17, and C18 in whole raw dairy cow milk from different production systems (conventional [CVN) vs organic (ORG)] and several countries of origin. Data from 18 studies and 13 countries were used to create a data set, which was used for statistical analyses. Data are reported in milk fat percent. The average concentrations of C15 and C17 in the raw milk from ORG system were greater (1.49 vs 1.12 and 1.17 vs 0.61%, respectively) than those from CVN farms (P < 0.05). However, no differences were found with regards to concentrations of C4 (3.21 vs 3.17%), C14 (10.70 vs 10.13%), and C16 (28.69 vs 26.82%), in the raw milk between ORG and CNV systems. Also no differences were obtained in the concentration of C6, C8, C10, C12, and C18. On the other hand, country of origin affected concentrations of SFA (P < 0.05). For example, raw milk from Ireland had lower amounts of C4 compared with milk from Belgium (1.33 vs 6.26%; P < 0.05). Additionally, the greatest concentrations of C6, C8, C10, and C14 were reported in Norway (3.11, 1.95, 4.43, and 13.88%, respectively), whereas the lowermost levels of those fatty acids were reported in Germany (0.82%), Switzerland (0.95%), Mexico (0.91%), and United Kingdom (7.13%), respectively (P < 0.05). Average C12 levels varied from 1.97% (Mexico) to 4.83% (Netherlands) (P < 0.05). Likewise, milk originating from US had lower means of C15 (0.63 vs 2.53%) and C17 (0.33 vs 1.61%) compared with milk from Germany (P < 0.05). Additionally milk form Germany had greater C16 levels compared with milk from UK (15.84 vs 41.31%) (P < 0.05). Means of C18 varied from 5.49 to 13.12% (China, P < 0.05). In conclusion, data from this meta-analytical study indicated that ORG farms were characterized by greater concentrations of some of the SFA compared with CVN system of management. This study also showed high variability in concentrations of SFA in the raw milk with regards to the country of origin.
