Abstract:
This Research was conducted to review the
role of oxytocin in mammary gland function and
development.
The literature reviewed , depended on
concerned books and many Journals as dairy
science , reproductive and fertility, Endocrinology
and web site.
From the results of some procedures used to detect
the role of oxytocin in milk removal and ejection,
mammary blood flow , intera mammary pressure
and milk yield .It is concluded that oxytocin
secretion is necessary for milk removal and
mammary gland development. Also oxytocin
facilitates milk ejection by inducing the contraction
of myoepithelial cell surrounding the mammary
alveoli.
Also Oxytocin together with estrogen and
progesterone stimulate the growth of
myoepithelial cells and is required for post partum
alveolar proliferation and mammary gland function.
This review also concluded that chronic oxytocin
treatment can reduce milk ejection in dairy cows.
