[The interrelation between the secretory function of the bovine udder and the amount of prolactin receptors on the membranes of the milk fat globules during lactogenesis].
The prolactin receptors number reaches its maximal level in proestrus. The data obtained suggest a correlation between high-affinity prolactin receptors concentration on the milk fat globule membranes during proestrus and the cow milk yield. The membranes may provide a model for assessing the functional state and secretory activity of the cow mammary gland.
