Physiology of milk let-downafter beta-receptor stimulation it is still unclear. Is it the relaxation of teatsphincter or better release and flow of milk from alveoli throughout themammary ducts?The autonomic reflex plays an important role in the regulation of milktransfer within mammary gland especially related to conditioning ofejection reflex like stereotype of milking routine. There is no cleat evidencefor conditioning of oxytocin release before teat stimulation.ReferencesBruckmaier, R.M. & M.
