When do cows lactate?

Summary:

At 15 months of age, a heifer (young female cow) is ready to breed and has never produced milk before. A young female cow (heifer) has her first calf at about 2 years of age. Once she has calved she starts her lactation cycle, which can last up to 12 months, but production of milk declines after around 10 months of lactation., and more items.

How do cows lactate?

The actual lactation begins at calving. It doesn’t only involve the production of milk, but also the development and function of the mammary gland, the metabolic and reproductive status of the cow, and the development of the calf.

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.

STAGE 1 – EARLY LACTATION – 14 TO 100 DAYS In early lactation, milk production begins at a high rate which continues to increase for three to six weeks after calving. This is known as peak milk production.
