Ideally, it is around 10 months long.
Lactation is the production of milk by the mammary glands and occurs during pregnancy and after birth if the offspring are being fed their mother's milk. The lactation period of sheep depends upon how long they are allowed to feed their young or how long they are milked for. When either of these cease, so does milk production.
Breastfeeding period.
Pigs have a gestation period of 114 days.
Lactation is just a more scientific term for "milking period." In other words, cows are producing milk for their calves or, in a dairy environment, for human consumption. Lactation can last as long as a calf is suckling which is typically 6 to 10 months or longer.

Time period within which the mammary glands produce milk.
Lactation is a term for the time period that a cow, or any other female mammal, is able to produce milk. What defines such a period is by seeing how tight and swollen the udder is on that cow. If the udder looks tight and swollen and all four teats look full, then she is obviously in her lactation period. This goes for all types of cows, beef and dairy alike.
Pigs have a gestation period of 114 days.
For beef and dairy cows, lactation period begins immediately after a calf is born. For beef cows, the lactation period ends when their calves are weaned off of them. For a dairy cow, the lactation period ends when she is not longer being milked and allowed to dry up so that she can focus on putting energy into growing the calf inside her. The dry period for a dairy cow is shorter than a beef cow's: two months for a dairy cow, and four to five months for a beef cow.
"Per lactation" refers to each period that a cow is producing milk. The majority of cows lactate for 6 to 10 months of the year, depending on the type of cow (beef versus dairy) and how long a producer wants her to be lactating for.
PRL (prolactin) __________ Stimulates lactation. The chief function of lactation is to provide nutrition and immune protection to the young after birth. Plus, lactation induces a period of infertility, which serves to provide the optimal birth spacing.
