Well, hormones and the removal of milk from the udder are the two key components that contribute to the maintenance of lactation. In order for lactation to begin again the cow must be bred to produce calves each year. Therefore, lactation is the result of having a successful reproductive program.

One article stated that a dairy cow will tend to lactate for 10 months or 305 days, post-calving. She is bred 90 days (or more, depending on the success rate for rebreeding her is) into her lactation period, and is pregnant for the remaining 6 or 7 months. She’s then dried off for the last two, before calving and starting the lactation cycle over again.
