Overview


Overview

Piglets suckling a sow.

The integration of the reproduction and lactation processes is particularly evident at the time of parturition. Parturition marks the time when the mammalian fetus is born and it is completely dependent upon the mother's ability to lactate in order to survive. The parallel timing of parturition and initiation of lactation (lactogenesis) is cirtical to the success of lactation and the immediate survival of the newborn. If the young is born prematurely, then the mammary gland may not have developed sufficiently to satisfy the developmental needs of the young. Conversly, if the gland begins lactating prematurely, then it may undergo involution before the neonate is born. In this Mother & Neonate Resoource, the sections on lactogenesis, or the mammary changes that occcur to initiate lactation, are combined with the sections about the newborn and about the first mammary secretion consumed by the newborn, the colostrum.

This Mother & Neonate Resource includes discussions on Lactogenesis, including Principles of Lactogenesis, Mammary Cytology Associated with Lactogenesis, Hormonal Changes Associated with Lactogenesis, Progesterone Involvement in Lactogenesis, and The Lactogenic Complex of Hormones: Insulin, Glucocorticoids, and Prolactin, as well as the effects of Estrogen, Growth Hormone, Local Effects, and the Extracellular Matrix, and the Hormonal Induction of Lactogenesis.

The Resource also contains sections on The Neonate and the Intestinal Absorption of Immunoglobulins, and on Colostrum, including Colostrum Formation, Immunoglobulin Transport in the Mammary Gland, Intestinal Protective Factors in Colostum and Milk, Bioactive Factors in Colostrum and Milk. In addition to supplying nutrients and factors directly involved in protection against pathogens, colostrum and milk contain a many components that may affect the growth and development of the neonate. This Lesson also includes information on colostral Enzymes, Growth factors, Carrier proteins, Immunoglobulins, Hormones, Immunomodulators, Steroids, Leukocytes, Intestinal protective factors, and Bioactive peptides.
