    The colostrum of horses (thoroughbreds) was extracted and fractionated to yield Gal(β1-4)GlcNAcα1-phosphate, which has not previously been detected in any mammalian milk or colostrum, as well as Neu5Ac(α2-3)Gal(β1-4)Glc. The structures of these saccharides were established by NMR spectroscopy and MALDI-TOF mass spectrometry.
