<h1 class="pgc-h-arrow-right" data-track="1" > cows are usually referred to as dairy cows</h1>
People who know the cattle industry know that cattle are mainly divided into dairy type, meat type, service type, and combined use type according to their use, and there is no dairy cow classification, let alone this breed. Usually we refer to dairy cows, such as Dutch cattle, Chinese Holstein cattle are excellent breeds of dairy cattle, in a good level of feeding management under the next lactation period of milk production of more than 9000 kg. In 1980, China's milk production was only 1.14 million tons, and in 2020, China's milk output was 34.4 million tons, the main reason for the huge increase was the rapid growth of the number of dairy cattle, and the average yield of a lactation period increased from less than 3000 kg to more than 7800 kg.
<h1 class="pgc-h-arrow-right" data-track="9" > cows have male and female</h1>
Cows are mammals, so cows also have a distinction between male and female, otherwise they cannot reproduce offspring and the race cannot continue. Bulls act as fathers and reproduce offspring, and cows produce their fetuses and enter the lactation phase to produce milk. Now the artificial insemination of cattle is very mature, so after the calf is born, most of the bulls are used for fattening and go to the slaughterhouse, and only a very small number of high-quality bulls will be retained as breeding cattle.
<h1 class="pgc-h-arrow-right" data-track="10" > how do cows distinguish between male and female? </h1>
The first and second sex characteristics of cows are very obvious, and male and female can be easily distinguished by observing the physical signs.
In short, no matter what type of cow, the cow will produce milk after giving birth to the calf, but the cow is not equal to the cow that produces milk, and it is not equal to the cow, so the cow also has a very obvious male and female distinction.
