摘要：The objectives of this study are to determine and compare the individual fatty acids profile of camel milk fat contents
and their correlation with the production systems, breed (Kenana, Butana, Nefidia), parity, and stage of lactation.
Camel milk fat samples were analysed for estimation of 37 fatty acids by using Gas Chromatography-Mass
Spectrometry (GC-MS). Fatty acids were divided into: Short Chain Fatty Acids (SCFAs) from C4:0 to C12:0, Medium
Chain Fatty Acids (MCFAs) from C13:0 to C16:1 and Long Chain Fatty Acids (LCFAs) from C17:0 to C22:6n3 and
their indices in milk of Sudanese Arabi camels (Kenana, Butana, Nefidia) were evaluated. The statistical model
included the effects of management systems, breed, parity and stage of lactation on fatty acids (FAs) within and
between breeds. First to second parity had relatively higher proportions of SCFAs in the milk of Kenana and Nefidia
camels as compared with Butana camel. Camel milk fatty acids composition were varied with stage of lactation, the
proportions of SCFAs were high at early and late stage of lactation compared to middle stage of lactation. LCFAs
(especially oleic (C18:1n9t) and Elaidic (C18:1n9c) showed an opposite trend to that of SCFAs and MCFAs. Although
no significant differences in camel milk fatty acids composition during the different parities were observed, the results
confirmed that parity order and stage of lactation contribute to the variations in camel milk fat composition.
