Milk ejection during automatic milking in dairy cows

Abstract

Tactile stimulation (manual or mechanical) of the mammary gland causes alveolar milk ejection through a neuro-endocrine reflex arc (Dzidic et al., 2004). Oxytocin is the hormone that induces the contraction of the myoepitelial cells surrounding the alveoli.
