It may seem paradoxical that male cows do not produce milk, but are called "cows". In fact, the name cow derives from its historical use. In ancient times, it was discovered that cows secrete milk after giving birth to calves, so cows began to be domesticated to produce milk. Over time, breeds of cows have been developed specifically for milk production.
However, there is no breeding selection for bulls during the breeding process. Therefore, male cows are very similar to female cows in terms of appearance, physiological characteristics, etc., but they do not have the ability to produce milk.
Despite this, it is still Xi to refer to both cows and bulls as "cows". This may be because cows play a more prominent role in milk production, while bulls are seen more as tools for breeding. In addition, in agricultural production, bulls and cows are often referred to collectively as "cattle" for ease of management and statistics.
In conclusion, even though male cows do not produce milk, they are still referred to as "cows". This reflects the historical and cultural background of humans in the domestication and cultivation of animals, as well as the rich diversity of languages and cultures.
