Centuries
Humans have been using cows to produce milk
Although all cows can produce milk
But there are only a few breeds of cows
Used by farmers for production
Milk for human consumption
In the United States
Holstein cows are the most popular dairy breed
It accounts for more than 90 percent of dairy production in the United States
Average milk production of Holstein cows
About 23,000 pounds
It is the crown of all cows
And it can be at 23 months old
The first calf was born
There is a strong demand for dairy products
India alone is a country
There are more cows than any other country
In India
There are about 60 million cows
According to 2019 data
The EU needs close to 155 million tonnes of milk each year

Now 2021
Human demand for dairy products
It will only rise, not fall
Although people's demand for milk is increasing day by day
But knowledge of dairy cows
But it is too poor
Today
It is widely believed that cows can produce milk for the rest of their lives
And the milk is like a tap
Open it
But in fact
Just like human mothers
Cows can only produce milk after they have given birth to calves
Milk is prepared for their babies
For the continuous production of milk
Cows are constantly conceiving
On a factory farm
Cows are usually 25 months old
The first conception is carried out using artificial insemination
After childbirth
Cows produce milk for about 10 months
Cows are selectively bred
And is given growth hormone to produce more milk
Until milk production drops
They are then artificially conceived again
This cycle continues until the cow is about 6 years old
Then their bodies are considered to have been used
No longer useful for this industry
Waste cattle are slaughtered and sold as low-grade beef
or for other purposes
The lifespan of naturally grown cows
Can reach 15 or even 20 years old
But the vast majority of cows raised by humans
The life expectancy cannot exceed 6 years
If you are sick before the age of 6
For example, lameness or mastitis
They will be slaughtered as waste cattle earlier
The death of the cow represents the end of human exploitation
Ironically
When you and I drink a cup of pure milk
The cow that produces this cup of milk
Maybe it's no longer in this world
