When you picture a cow, you’ll most likely visualize a farmer sitting down beside her holding a bucket as they milk her. Whether it is done by hand or through modern technology, the action of milking is an important part of owning milk-producing cows. But do cows really need to be milked?
The age, breed, and purpose of the cows are important factors in determining whether or not she needs to be milked.
A dairy cow who is kept for milk production and does not have a calf by her side needs to be milked daily because she is a breed of cow that produces a lot of milk. This prevents pressure from building up in her udder.
A dairy cow who has a calf at her side does not necessarily need to be milked daily because the nursing calf will prevent issues with excessive milk buildup in the udder. A cow bred for meat production never needs to be milked as she will typically produce just enough milk for her calf.
Why is Milking Cows Important?
It is important for a cow to be routinely milked to keep her healthy and promote continued production of milk in the future. Dairy cow breeds are chosen because of the high amount of milk that they produce. Their calves don’t need milk for as long as the cows produce it, so the excess is usually collected for human consumption.
Once cows are milked, they’ll create more milk and need to be milked again to reduce the weight on the udders.
What Happens to a Cow If You Don’t Milk It?
Failure to milk a dairy cow who is kept for the sole purpose of milk production and does not have a calf by her side will result in pressure building up in her udder. This could lead to discomfort, bruising, udder injury, swelling, engorgement, rupture of the skin, and potentially life-threatening conditions, such as mastitis.
Do Cows Produce Milk When They are not Pregnant?
Cows need to be pregnant and give birth in order for milk production and release to occur. The production of milk in cows is triggered by the complex interaction of several hormones, which come into play during pregnancy.
Typically, during the second and third trimesters of a cow’s pregnancy, hormones such as estrogen and progesterone are produced, which stimulate the development of the milk duct system in the udder.
Another notable hormone produced is oxytocin, which allows the secretion of milk to occur. The levels of prolactin (a protein) are stimulated when the cow’s udder is milked by the milking machine and this needs to take place to ensure the continuation of milk production.
Can a Cow Die If Not Milked?
If a cow’s udder bursts and becomes infected, she could die. Furthermore, if the cow develops mastitis and is not treated in good time, she could die due to complications from the condition.
However, keep in mind that this is more likely to occur in cows that are solely kept for milk production and don’t have calves by their side, because they require daily milking.
Do Cows Feel Pain When Milked?
Healthy bovines don’t feel pain when milked especially if it’s done on a routine basis. A cow’s udder is made by nature to withstand a calf’s suckling, and by extension, to a human or machine milking. However, there are circumstances when the milking process might be painful for cows:
This is an inflammation of the mammary gland that is caused when bacteria enter the udder.
- Lesions on teats
If a cow has suffered damage to her teats, milking will be painful.
- Infrequent milking
If for one reason or another, a cow isn’t milked at the usual intervals, buildup will occur in the udder and milking will be painful.
How Often Do Cows Need to Be Milked?
How often a cow needs to be milked depends on the age, breed, and purpose of the cow:
- Dairy cows strictly intended for milk production need to be milked at least once a day. Most farmers milk their cows two to three times a day.
- A dairy cow who has a calf at her side may produce enough milk to allow for milking once a day. That said, she does not necessarily have to be milked daily because her nursing calf will prevent issues arising from excessive milk buildup in the udder. When the calf is naturally weaned, you may need to increase the frequency of milking especially if the cow’s milk does not dry up naturally.
- A meat breed cow does not require milking. When the calf is weaned, her milk supply will dry up on its own in two to five weeks.
How Many Years Can Cows be Milked?
The lifespan of an average cow is about 18 to 20 years. Cows start producing milk from the age of 2-3 years, that is after she gives birth to her first calf. In commercial settings, dairy cows are typically retired when they are 6 to 7 years old and/or their milk production stops (whichever comes earlier)
In small farm settings, you can often find a 10+ years old cow still producing milk regularly. The longevity of a cow’s milk production depends on several factors, including overall health, breed, and access to quality feed.
Why are Cows Milked So Early in the Morning?
Some of the reasons why cows are cows milked so early in the morning include:
- Cows are easier to handle early in the morning when they are still sleepy.
- In a commercial setting, it’s so that the milk can be pasteurized and shipped out for sale in good time.
- If cows don’t get milked on time, they can get very uncomfortable, cranky, and noisy.
How Do Wild Cows Milk Themselves?
Wild cows simply nurse their cows and don’t need to find any other way to milk themselves. In the wild, cows don’t produce as much milk as domesticated cows since they eat grass and food that is lower in nutritional value.
Additionally, they have not been specifically bred to produce that much milk. As a result, they only produce enough milk to sustain their nursing calves.
