TLDR
In this article, the average N -acetyl neuraminic acid (NANA) content of milk from cow, sheep, goat, mare, donkey and sow (about 10 samples from each species) was found to be 17.7, 10.1, 6.4, 6·1, 12·0 and 64·0mg/100 ml.Abstract:
Average N -acetyl neuraminic-acid (NANA) content of milk from cow, sheep, goat, mare, donkey and sow (about 10 samples from each species) was 17·7, 10·1, 6·4, 6·1, 12·0 and 64·0mg/100 ml, of which 14·2, 8·4, 3·2, 3·1, 5·0 and 53·7mg/100 ml respectively was in the casein fraction. The NANA content of casein showed marked species variation ranging from an average of 2·18 % for the sow to 0·09 % for the goat. About 28 % of the casein NANA of mare's milk was liberated in the fraction soluble in 12 % TCA by the action of rennin at pH 6·6 compared with 75 and around 100 % for donkey's and sow's milk respectively; about half the total NANA in the casein of cow's, sheep's and goat's milk was released under the same conditions.read more

Protein and fat composition of mare's milk: some nutritional remarks with reference to human and cow's milk
TL;DR: Mare's milk shows some structural and functional peculiarities that make it more suitable for human nourishment than cow's milk, considering principal protein fractions and fatty acids.

Composition of milk.
TL;DR: Interspecies Differences in the quantitative composition of milk probably reflect differences in the metabolic processes of the lactating mother and in the nutritive requirements of the suckling young.

Concentrations of Sialyloligosaccharides in Bovine Colostrum and Milk during the Prepartum and Early Lactation.
TL;DR: Bovine colostrum, especially that collected immediately after parturition, may be suitable as a source of 3'SL and other sialyloligosaccharides for use as additives by the food or pharmaceutical industries.

The thiobarbituric acid assay of sialic acids.
TL;DR: This chapter discusses the different aspects of thiobarbituric acid assay of sialic acid, which is suitable for measuring the release of bound sialoic acid by sialidase and hydrolysis of sIALic acid-containing material must be carried out for the measurement of total sialsic acids.

Étude comparée des caséino-glycopeptides formés par action de la présure sur les caséines de vache, de brebis et de chèvre
Charles Alais,Pierre Jollès +1 more
TL;DR: In this article, the caseino-glycopeptides obtained after rennin digestion of different caseins contain a non-peptidic part, the amount of which varies according to the origin of the casein (cow, goat or sheep) and to its state of purity (entire casein, casein α or κ).

Sialic Acid as an Index of the κ-Casein Content of Bovine Skimmilk
TL;DR: In this paper, the sialic acid content of skimmilk proteins has been examined, using a modification of Warren's thiobarbituric acid method, and it was concluded that sial acid measurements can be used as an index of the intact κ -casein content of such mixtures.
