It is a large domestic animal belonging to the order Artiodactyla and family Oxidae in the mammalian class. Known for its milk production capacity, it is the main source of global dairy production. Breeding has a long history, as early as ancient Egypt in BC, humans began to domesticate and utilize dairy products from cows. Dairy products are not only nutritious and contain high-quality protein, calcium, and vitamins, but also have a wide range of uses and can be processed into various dairy products such as milk, cheese, butter, etc. The living habits are relatively mild, usually grazing on pastures or raising in captivity. It also holds a place in culture and is often seen as a symbol of diligence and abundance.

It is a dairy cow breed originating from the Netherlands, renowned for its high milk yield and excellent milk quality. Cattle have a large body size and strong adaptability. Their fur color is usually black and white patches, with a few being red and white patches. The fat content of milk is usually between 3.5% and 4.5%, while the protein content is around 3.0%. Due to its excellent milk production performance, Holstein cattle have become one of the most important breeds in global dairy farming. Holstein cattle not only play an important role in dairy production, but their meat performance cannot be ignored. Due to its large size and well-developed muscles, Holstein beef is also popular in the market.

Cows are mammals belonging to the family Taurus in the order Artiodactyla. They are tall and have a well proportioned structure, thin skin, low fat content, short capillaries, and often have distinct black, white, or yellow fur. Chinese Holstein cattle are the main dairy cow breed in China, currently distributed throughout the country, mainly in northern grassland areas such as Heilongjiang, Inner Mongolia, and Xinjiang, while other areas are distributed in urban and suburban areas and some suburban rural areas. Cattle are mainly fed with coarse feed, silage feed, energy feed, and protein feed. Adding seasonings such as spices, sodium saccharin, sodium glutamate, and organic acids to the feed can increase the cow's feed intake and milk production.

A cow is a subgenus of the subfamily Oxinae, and is a female cow. Supplement concentrated feed at 1.0-1.5kg per day; After 120 days of production, 1.5~2.5kg of concentrated feed should be supplemented daily to facilitate milk production and increase breeding and conception rates for cows. Can produce milk and have offspring. The breed of cow and the breed of bull, although tall and strong, have unstable genetics, which can easily lead to inbreeding, offspring degeneration, and low economic benefits.
