If cows are not milked, will they leak? It depends on the volume of milk produced daily and on the anatomy of the teat.A dairy cow can easily give 40 liters of milk a day. This large volume cannot be absorbed. The teats will eventually leak, and the cow will be in severe distress and pain if not milked.
Other breeds of cattle that are not bred for milking produce just enough milk to feed one or two calfs. If the calf dies the milk production will be stopped whithout so much problems and most of the milk will be reabsorbed.
Leaking of milk under normal husbandry circumstances does occur sometimes, just before the normal time of milking. The reason is that the conditioned stimuli (sound of the milking machine) will cause the milk to 'rush in' and 'want out'. Farmers don't like this, because the milk on the outside is a great feeding ground for all kinds of bacteria. And these bacteria could make the milk go sour or infect the udder thus leading to mastitis.
And finally there is something called 'dry cow management'. This means that cows are not milked for 6 weeks or more prior to the next calfing.
Hope this helps
