More than 800 types of dairy cattle are perceived around the world, some of which adjusted to the neighborhood atmosphere, others which were reproduced by people for particular employments.
Breeds fall into two fundamental composes, viewed as either two firmly related species, or two subspecies of one animal categories. Bos indicus (or Bos taurus indicus) steers, additionally called zebu, are adjusted to hot atmospheres. Bos taurus (or Bos taurus) are the ordinary dairy cattle of Europe, north-eastern Asia, and parts of Africa – they are alluded to in this rundown as "taurine" steers, and many are adjusted to cooler atmospheres. Taurus/indicus cross breeds are broadly reproduced in numerous hotter locales, consolidating qualities of both the genealogical sorts, (for example, the Sanga steers of Africa).
In a few sections of the world further types of steers are discovered (both as wild and tamed creatures), and some of these are connected so intently to taurine and indicus dairy cattle that interspecies half breeds have been reared. Cases incorporate the Dwarf Lulu dairy cattle of the mountains of Nepal with yak blood, the Beefalo of North America with buffalo qualities, the Selembu type of India and Bhutan with gayal qualities. The Madura type of Indonesia may have banteng in its parentage. notwithstanding these rich half and halves, there are barren intersections, for example, the male Dzo of Nepal, a cows yak crossing which is reproduced for rural work - like the donkey they must be constantly reared from the parent species.
