The exact time of initiation of milk secretion was determined in pregnant rats killed on the 15th, 20th, 21st and the day of parturition as was done in earlier experiments (13). The day following the finding of spermatozoa in the vaginal smear was defined as the first day of pregnancy.

Lactogenesis: Initiation of Milk Secretion. Stage I lactogenesis starts approximately 12 weeks before parturition and is heralded by significant increases in lactose, total proteins, and immunoglobulin and by decreases in sodium and chloride, and the gathering of substrate for milk production.
The rate of milk secretion in the early postpartum period (Figure 1) started low, less than ml/day up to 36 hr postpartum, then began to rise almost linearly to level off at about ml/day at 96 hr postpartum (Neville et al., ).The concomitant change in the citrate concentration is shown in Figure 5 replotted from Neville et al.

Concentrations and secretion rates of macronutrients and major ions in human milk during lactogenesis (birth to 8 d) and late lactation (greater than 6 mo postpartum) are reported. Lactation, secretion and yielding of milk by females after giving birth.
The milk is produced by the mammary glands, which are contained within the breasts. Pituitary hormones play a central role in lactation.

Around this time, the breasts become engorged, tense, tender and feel warmth. When the progesterone and estrogen are withdrawn following delivery. Lactation describes the secretion of milk from the mammary glands and the period of time that a mother lactates to feed her young. The process naturally occurs with all post-pregnancy female mammals, although it predates humans the process of feeding milk is also called breastfeeding or n infants often produce some milk from their own breast tissue, known colloquially.

Folley. The book that contains this article and many other articles of great historical interest, Lactogenesis: The Initiation of Milk Secretion at Parturition (Philadelphia, University of Pennsylvania Press,) was, at this writing, still available in the antique book market and is well worth examination.
By Lactogenesis is the onset of milk secretion. During the second half of pregnancy, secretory activity accelerates and colostrum is produced. Comprises of two phase: Stage I: capacity of the breast to secrete milk during later pregnancy Stage II; onset of copious milk secretion occurs after birth (days two or three to eight postpartum).
The pathways for milk secretion and synthesis by the mammary epithelial cell. I: Exocytosis of milk protein, lactose, and other components of the aqueous phase in Golgi-derived secretory vesicles. II: Milk fat secretion via the milk fat globule. III: Direct movement of monovalent ions, water, and glucose across the apical membrane of the cell.
Initiation of Milk Secretion or Lactogenesis • Although small amount of milk secretion occurs at later months of pregnancy, a free flow of milk occurs only after the delivery of the child.
• The milk, which is secreted initially before parturition is called colostrum. Artificial Intelligence Engines: A Tutorial Introduction to the Mathematics of Deep Learning Paperback by James V Stone on *Best Price online*.

Milk production is essential for optimal feeding of infants and has a direct impact on growth, development, and health in neonatal period .Breastfeeding is influenced by nutritional and nonnutritional factors (associated with endocrinology, health, climate, and management) that affect milk synthesis and secretion.
Parturition In Domestic Animals: A Review. Author(s): Purohit G. Abstract. Parturition is the process of delivery of the fully grown fetus on the completion of the normal pregnancy period. Parturition is an interesting biological process in the sense that the uterus that was quiescent during the entire pregnancy starts contracting and the cervix.
Lactogenesis, defined as ''the onset of copious milk secretion around parturition" (Neville and Neifert,p. ), is believed to be triggered by the decrease in progesterone following parturition.
Incomplete delivery of the placenta has been shown to delay lactogenesis, presumably because it is accompanied by continued high levels of. After parturition, elevated levels of prolactin and withdrawal of estrogens and progesterone results in the onset of milk secretion (lactogenesis).
The breasts must have undergone appropriate growth and development beginning in puberty and completed during pregnancy for milk secretion to occur.

Cohen and Massey () have pointed out that in animal reproduction ‘much more passes between the generations than simple information coded for by DNA’. In mammals, quite apart from factors such as ‘cultural inheritance’, the observation acquires tangible validity in the secretion of milk.
Lactogenesis II is the initiation of copious milk secretion and is triggered by the delivery of the placenta at birth, and the resulting withdrawal of progesterone from circulation. “Since it is the delivery of the placenta that initiates the fall in progesterone, lactogenesis II is therefore delayed until progesterone clears from the.

conclusion that the initiation of lactation began in two stages: first the gland developed the ca-pacity to synthesize the unique milk con-stituents such as lactose during pregnancy, and then at parturition there was a rapid initiation of copious milk secretion.5 These events were subsequently termed lactogenesis I and II, re-spectively.
Revised and updated, the eighth edition ofAnatomy and Physiology of Farm Animals remains the essential resource for detailed information on farm animal anatomy and physiology.

Milk consists of water, protein, lipids, carbohydrates (mainly lactose), minerals and vitamins, and is the secretory product of mammary epithelial cells (MEC) in all lactating mammals [1–62] (Table 1).The mammary gland is a compound, tubulo-alveolar structure with a merocrine/apocrine mode of secretion .Proteins, some amino acids (AA), and fats are synthesized and secreted by MEC in.

Immunoglobulins form an important component of the immunological activity found in milk and colostrum. They are central to the immunological link that occurs when the mother transfers passive immunity to the offspring.
The mechanism of transfer varies among mammalian species. Cattle provide a readily available immune rich colostrum and milk in large quantities, making those secretions.Background. Milk consists of water, protein, lipids, carbohydrates (mainly lactose), minerals and vitamins, and is the secretory product of mammary epithelial cells (MEC) in all lactating mammals [1–62] (Table 1).The mammary gland is a compound, tubulo-alveolar structure with a merocrine/apocrine mode of secretion .Proteins, some amino acids (AA), and fats are synthesized and secreted by.Early milk, produced from approximately 16 weeks of pregnancy into the first postpartum days; rich in antibodies, higher in protein, and lower in fat than mature milk, with laxative effect to clear meconium and promote excretion of bilirubin.
