© 2019 The Author(s) The article highlights the experimental results on calf demand provision by mammary gland secretion during the first days of post-natal development. Changes in mammary gland secretion content during the transition process from colostrum to natural milk were showed. Lactoferrin level changes were demonstrated. Population-based composition of colostrum somatic cells was determined. A hypothesis concerning apoptosis role of the somatic cells and neutrophils’ burst was presented. The present study highlights calf provision with mammary gland secretion during the first 10 days of the postnatal development.
