These results suggested that BPL stimulates
mammogenesis (Fig.
Effect of pre-pubertal nutrition on mammary growth : Negative effects of high feeding level in the pre-pubertal period on
mammogenesis, especially a reduced amount of parenchyma tissue and a lowered future MY have been observed in several studies in both dairy and beef heifers (Harrison et al., 1983; Capuco et al., 1995; Buskirk et al., 1996, Sejrsen et al., 2000).
The ewe that is fed poorly during the last part of gestation will have a decreased milk production potential because this is the time when
mammogenesis occurs.
Mammogenesis is influenced by the nutrition of gilts during pregnancy.
Chilliard (1992) reasoned that short-term effects led to better
mammogenesis and lactogenesis during the time around parturition, or better digestive adaptation, and that long-term effects led to a better availability of body reserves at calving.
IGF-1, which is derived mainly from the liver and GH-dependent (Breier et al., 1988; Bass et al., 1991), acts as a mediator of
mammogenesis and regulates the yield and components of milk in mammary epithelial cells (Breier and Sauerwein, 1995; Plath-Gabler et al., 2001).
Cellular localisation of GH receptor in the bovine mammary gland during
