About biological characteristics A domestic cow is a female cow, which is a subspecies of the wild bull. If we talk about the classification of cattle by age, then a bull is an adult male, and young animals (a child of a cow) are a bull, a calf or a heifer.
WHAT IS A MINI JERSEY COW? Mini Jersey cattle are exactly what their name suggests: a smaller version of a standard-sized cow. The miniature classification refers solely to their size. Mini Jersey cattle do not have tiny heads and legs attached to a large body. If you see a jersey that fits this description, it is technically a midget and not a mini. Dwarfism in Jersey cattle is a genetic defect of the D2 gene.
Intensive hunting led to the gradual disappearance of the wild bull. In the Middle Ages, it was already a rarity in European forests, and its last specimen is believed to have died of disease in 1627 near the Polish village of Yakturov. It is not clear exactly where the aurochs was first domesticated. Places such as South Asia, the Mediterranean, and the Iberian Peninsula are mentioned. Some researchers suggest that the aurochs was domesticated in different parts of its extensive range.
Methods and assessment of accounting for the milk production of animals Breeding highly productive cows is one of the most profitable areas of animal husbandry. Dairy products are in high demand all over the world - to meet all needs, more milk must be produced. Progressive farms devote a lot of effort and attention to the scientific approach to animal care. Evaluation of cows by their own productivity is a quantitative and qualitative characteristic of milk yields for a certain period of time. Not only the volume is checked, but also the density, as well as the percentage of fat in it.
