How does lactation work in a cow? A simple mechanism that surprises.
This, why do cows still give milk, can be misleading only at first glance. A cow does not produce milk continuously throughout its life, but in lactation cycle closely related to reproduction. Milk production starts after calvingwhen the body responds to hormonal changes that prepare the calf to eat. A key role is played by prolactinwhich stimulates the mammary gland cells to produce milk, and oxytocin, responsible for its flow from the udder during suckling by the calf or milking. This is the regular emptying the udder maintains lactation: the more often milk is removed, the stronger the signal to continue production. When milking stops, the body gradually reduces milk secretion and goes into the dry period. Therefore, the answer to the question, why do cows still give milk, is: not "continuously," but for a specific period after parturition, thanks to the interaction of hormones, the animal's condition, nutrition, and regular milking. In practice, high lactation efficiency also requires good udder hygiene, proper perinatal care, and support for metabolic health, which is of great importance for the well-being and quality of milk.
Why Cows Still Give Milk - Facts That Debunk Popular Myths
To the question why do cows still give milk, the answer is simple: a cow does not produce milk "by itself" endlessly, but starts lactation? After calving, like other mammals, milk is produced in the udder under the influence of hormonal changes, and its further production depends on the regular emptying of the mammary gland. This is why regular milking is so important – if milk is not removed regularly, the body gradually limits its production.
This, why do cows still give milk on the farm also results from proper nutrition, access to water, comfort of living and care for health. High milk yield The importance of proper nutrition is not a coincidence: a cow needs a well-balanced feed ration, support during the post-calving period, and effective milking hygiene and udder care. The Ruminta brand develops precisely such solutions for dairy cattle breeding – from supplements that support metabolism and regeneration to post-milking hygiene products that help protect the milking process. udder health and maintain good milk quality.
It's also worth clearing up another myth: the constant presence of milk on the market doesn't mean that a single cow is in uninterrupted lactation throughout her life. In practice, continuity of production in a herd is the result of reproductive planning and managing the subsequent lactations of individual animals. Therefore, why do cows still give milk should be understood not as a biological "infinity", but as the result of physiology, regular milking, proper care and a well-run farm.
What supports healthy and efficient lactation - nutrition, hygiene, and modern prevention
If we ask, why do cows still give milk, it is important to remember that the scale and stability of lactation is determined not only by the hormonal mechanism itself, but also by daily practice in the barn. Correct energy balance, especially after calving, when energy requirements increase rapidly. The feed ration should support dry matter intake, rumen function and reduce the risk of ketosis, therefore a well-selected diet is important. supplementation of dairy cows ? energy, vitamins, minerals and preparations supporting metabolism. Support in around calving, when the risk of dehydration, loss of appetite and metabolic disorders increases.
Equally important is milking hygiene and regular udder careClean teats before and after milking, proper drying, and the use of protective preparations help limit microbial pressure and reduce the risk of mastitis, which reduces milk yield and quality. Hygiene of bedding, milking equipment, and installations is also important, because healthy lactation begins with limiting sources of infection. A practical example of this approach is the ruminta.eu offer, including solutions for dairy cows, goats, and sheep - from energy and electrolyte preparations to post-milking hygiene and care products. Products such as Energymax Vit, Maxdrink, and Iodinedip are part of modern prevention that supports udder health, the condition of the animals and the continuity of milk production.
