Cows are one of the important agricultural animals, mainly used to produce milk and meat. As mammals, cows belong to the order even-toed ungulates and are relatively docile, adaptable and fertile. Across the globe, there are several different breeds of dairy cows that differ significantly in appearance, milk yield and meat quality.

The body of a cow is usually large, strong limbs, hair divided into multiple colors, such as black and white, brown or all black. Cows have a complex digestive system in their stomachs, including four stomachs, namely rumen, reticulum, umasum and abomasum, which enable them to efficiently digest coarse fiber-rich forage. This feature of the digestive system allows cows to utilize a wide range of plant resources, especially in grasslands and pastures, to maximize their energy.

The main value of cows is in the production of dairy products. Rich in protein, fat, vitamins and minerals, milk is an important part of the human diet. With proper feeding and management, cows can produce a lot of milk every day. With the development of science and technology, modern dairy industry has adopted various advanced methods to improve milk yield and milk quality of cows.

In addition to producing milk, meat from cows also occupies an important position in the global market. Beef is an important part of many cultural diets and is widely recognized for its nutritional value and taste. In order to meet the growing market demand, many farms adopt scientific breeding methods to improve the growth rate and meat quality of beef cattle.

In the breeding process, the health management of dairy cows is particularly important. They have high environmental requirements, and ideal temperature, humidity and a clean living environment are key to keeping cows healthy. At the same time, regular veterinary check-ups and vaccinations can effectively prevent diseases and ensure the normal production of cows.
