mammary secretion

The visual appearance and somatic cell count of mammary secretions collected from primigravid heifers during gestation and early postpartum.

Despite the terminology used by consumers, it is illegal to sell soy milk under that name in the European Union, where - with certain exceptions - EC Regulation (1898/87) has restricted the term 'milk' to mammary secretions since 1987; in such countries the term 'soy drink' is commonly used.
