Abstract
Changes in the sialoglycoconjugate content of cow, goat and ewe milks during the different stages of lactation were studied. Total and ganglioside sialic acid contents were high in the colostrum and decreased thereafter until the end of the period analysed in the three ruminants considered. Goat milk shows a total sialic acid content higher than cow and ewe milks, whereas cow milk contained approximately 10 times more ganglioside sialic acids than goat and ewe milks. Regarding N-glycolylneuraminic acid content, ewe and goat milks have percentages (in the total sialic acid content) of 60-80% and 30-60% respectively, whereas cow milk has 6-30%. The distribution of the different sialoglycoconjugates has also been determined in cow milk pointing out a content of oligosaccharide-bound sialic acid higher in colostrum than in mature milk.
