Happy hormone injections for cows help make milk more delicious and nutritious

The cows raised in the present era are always under great pressure to meet the production of human milk.

One of the main reasons why we drink milk is because of calcium - this element will make your bones and teeth strong, stronger muscles (including the heart muscle) and stimulate blood circulation.

In a recent study, scientists at the University of Wisconsin-Madison discovered a method that could increase calcium levels in milk by giving cows regular milk injections of serotonin. This hormone is thought to be able to create feelings of happiness.

If you think that the life of a dairy cow is quite fun and relaxed, just wandering the green grass under the cool fresh sky, you must be wrong.

The increase with the dizzying speed of dairy and dairy enterprises is currently the most unnatural production. Modern dairy farms cram hundreds or even thousands of cows. Each animal is bred so that it can produce an average of 6 to 7 times more milk than the cows of the previous century. Cows are continually pregnant to produce milk. And after about 3 to 4 years, when their milk production declines, they will be resold, slaughtered to make hamburgers.

It is this kind of feeding that causes dairy cows to have many different problems. About 5-10% of American dairy cows suffer from low calcium levels, also known as hypocalcemia . This disease causes digestive problems in cows, reducing their ability to fight disease and fertility. Since then, they produce less milk.

Laura Hernandez, a professor of biology leading the research program and her team conducted tests on 24 crossbred cows between Jersey and Holstein breeds. After serotonin treatment, cows began to produce significantly higher levels of calcium.

After serotonin treatment, cows began to produce significantly higher levels of calcium.

At the time, farmers and scientists tried other methods to improve the mood of the cow, including giving them relaxing music and even reading poetry. These methods all show that the amount of milk has increased significantly because of reduced stress in cows. However, the quality of milk is still not much improved.

The method of serotonin use for treatment results in the opposite. Although it makes milk more nutritious, it does not significantly affect the cow's milk production.

Serotonin is mainly found in the gastrointestinal tract and central nervous system. About 80% of the total serotonin of the human body is in the intestine, used to regulate intestinal movement, the remaining 20% ​​is synthesized in central nervous cells, where it has many different functions: conditioning Mood correction, appetite, sleep, muscle contraction and some cognitive functions.

Serotonin is impaired, leading to feelings of boredom, decreased desire, reduced interest or easy anger, difficulty in completing the job.
