Definition of colostrum in English:



  • The first secretion from the mammary glands after giving birth, rich in antibodies.

    ‘Antibodies acquired through colostrum at birth are critical to the newborn's health, but only last three to six months and while present can block the immune response to a vaccine.’
    • ‘Similar proportions of mothers in both groups began breast feeding within 12 hours of birth and reported feeding colostrum.’
    • ‘As the first milk that comes from a cow's udder, colostrum is rich in growth factors, antibodies and high-quality protein, making it a potentially valuable supplement for bodybuilders.’
    • ‘For example, for the first few days after delivery, a woman's breasts produce a thick, yellowish form of milk called colostrum.’
    • ‘During the first 2 to 3 days of life, your baby will get a special kind of thick milk called colostrum.’
    • ‘It is unlikely that the small amount of colostrum ingested during the first feeding will significantly alter the birth weight.’
    • ‘Samples of serum, whole blood, colostrum, and milk were frozen until analysis.’
    • ‘The colostrum supplies antibodies needed by the foal to fight off disease, and these antibodies are absorbed through the gut only during the first 24 hours of life.’
    • ‘Lambs which drink sufficient colostrum soon after birth will be protected from a disease common in intensive indoor lambing flocks in Pembrokeshire.’
    • ‘A mare has only a limited supply of colostrum, which contains antibodies essential for the foal.’
    • ‘It is critical that the calf receives adequate levels of colostrum immediately after birth.’
    • ‘A woman with normal breasts produces sufficient colostrum during the last trimester and at delivery to sustain twins or a large term baby until her milk comes in.’
    • ‘We therefore implemented a new system, whereby all our newly-calved heifers are milked immediately for their colostrum.’
    • ‘Many people do not realise the importance of continuing to give colostrum, mixed with milk replacer, for the first two weeks.’
    • ‘The colostrum that mothers produce in the first few days after birth is not actually ‘milk’ at all, but an immensely important golden syrup rich in nutrients and immunoprotective proteins.’
    • ‘Although absorption of antibodies via the intestine declines rapidly, the feeding of colostrum is still beneficial after 24 hours as it provides local protection in the intestine.’
    • ‘It is most important that lambs get an adequate supply of colostrum as soon as possible after birth.’
    • ‘The immunity to disease passed through the mother's colostrum called ‘maternal immunity’ usually lasts for several weeks in the puppy's system.’
    • ‘I was told that my baby was not getting enough to eat because my milk had not come in yet and that colostrum was not enough.’
    • ‘One day I inadvertently put donor milk that had a high content of colostrum in the bottle.’
