Faye B., Konuspayeva G., Narmuratova M., Loiseau G.. 2008. Journal of Camelid Science, 1 : p. 49-54. International Conference of the Society of Camelids Research and Development, 2006-04-15/2006-04-17, Al-Ain (Emirats arabes unis).

Samples of camel milk both from Bactrian and dromedary were collected in 4 regions from Kazakhstan at different seasons. The fatty acid composition of those milk samples from different species of camel was compared by taking in account the proportion of the major part of the saturated, mono-unsaturated and poly-unsaturated fatty acids and compared with literature data. The results showed a higher part of saturated fatty acids in cow (78.6%) and goat (75.3%) compared to camel (68.6 for Bactrian and 69.7% for dromedary) and mare (50.6 % only) milk fat. The mono-unsaturated fatty acids are in highest proportion in camel (29.3 % for Bactrian and 27.6% for dromedary) compared to mare (25.8%), goat and cow (20.7 and 20.8% respectively) milk fat. At reverse, camel milk fat is the lower in poly-unsaturated fatty acids in our sample (2.0 and 2.5% respectively for camel and dromedary) compared to goat and cow (3.4 and 3.8 % respectively). Mare milk is particularly rich in linoleic and linolenic acid (11.3 and 11.9% respectively). In camel, the mono-unsaturated fatty acids are in lower proportion in autumn and higher quantity in summer. No differences were observed according the regions. (Résumé d'auteur)
