“…In this study the ovine milk had a significantly lower amount of SFA (57.5%) than was detected by Ostrovský et al 13 and Revilla et al 14 (mean values 65 and 78%, respectively). In addition, the composition of SFA differed significantly from our results.…”

This is a comprehensive study of fatty acid (FA) profiles in milk from bovine, caprine, ovine, asine, and equine species. Milks from these species are universally common as constituents in a variety of different food and dairy products. We have obtained structural information on FAs, and discussed their correlation to health effects. The extracted fat from all species were derivatized to FA methyl esters for analysis by GC-MS. Large differences in the lipid content and FA composition between ruminants and non-ruminants were observed. Ovine milk showed the highest lipid content of all the animals tested, both ruminants and non-ruminants. Among the ruminants, bovine milk was richer in saturated FAs (69.7%) than ovine-and caprine milk (57.5 and 59.9%, respectively). Ovine milk contained the highest amounts of monounsaturated FAs (39.1%) and also odd-and branched-chain FAs (5.5%). Milk from the monogastric animals, mares and donkeys, were highest in polyunsaturated FAs with a content of 19.3 and 14.2%, respectively. The assumed health negative trans FAs were analyzed to be highest in the ruminant milk (0.7-1.0%). Milk from these species contained also the highest amount of the health beneficial CLA (0.4-0.7%).Practical applications: This is a comprehensive study of milk from five species analyzed under identical conditions. The different fatty acids and their derivatives are increasingly important components because of the contradictory reports on positive and negative effects on human health. New information on the composition of milk from different species is of great importance. The results may give valuable information to producers and nutritional advisors on the consumption of milk and milk products.Abbreviations: FA, fatty acid; OBCFA, odd-and branched-chain fatty acid; SFA, saturated fatty acid 1036Eur.

“…The CLA content of the Boutsiko ewes milk in this study was similar to the concentrations reported by Ostrovsk y et al (2009) with ewes from different breeds grazing fresh pasture. The CLA content in milk of pasture-grazed ewes and cows was found to be higher compared to animals fed a total mixed ration (Collomb et al 2008;Ostrovsk y et al 2009). Figure 1 shows that in the Boutsiko breed, the composition of short-, medium-and long-chain FA in milk remains constant regardless of the season, with a tendency for increasing long-chain FA in mid-and late lactation compared with the early phase of lactation in which short-chain FAs seem to have a higher proportionate.…”

In this study, the chemical and microbiological characteristics of ovine milk from three indigenous Greek breeds was assessed. The breeds selected for this study were Boutsiko, Frisarta and Karagouniko. The milk yield of each breed was recorded at the early, mid‐ and late stages of lactation for two consecutive years. Among the three breeds, the average milk compositions obtained were similar for protein, lactose and total solids; however, fat values were significantly lower in Frisarta milk compared with Boutsiko and Karagouniko milk. The major fatty acids (FAs) in ovine milk were palmitic and oleic. The microbiological quality of Boutsiko and Karagouniko milk was superior to Frisarta milk.
