|---|---|
 breast development and maturation | -begins during puberty -differentiation into laborular structure -no functional alveoli |
| pregnancy; breast development and maturation | stimulates growth and proliferation of duct system and formation of large lobules |
| synthesis and secretion of milk components (lactation) | -stimulated by prolactin -stimulated by suckling |
| ejection of milk form the gland (lactation) | -release of milk into large glands -stimulated by oxytocin -stimulated by suckling or baby's cry |
| colostrum | -produced during the first 2-3 days -rich in protein, particularly IgA and minerals -lower in CHO and fat |
| transitional milk | -produced between the 3rd and 6th day -fairly high in protein -lower in CHO and fat |
| mature milk | -established between the 10th day- 1st month -lower in protein, higher in lactose and fat |
| foremilk (initial) | lower in fat, rich in other nutrients |
| hindmilk (later) | -higher in fat -promotes satiety |
| milk volume lactation (first 6 months) | 750 ml/day |
| milk volume lactation (second 6 months) | 300-900 ml/day |
| milk volume lactation (second year) | 200-600 ml/day |
