This is a list of some of the cattle breeds considered in the United States to be wholly or partly of American origin. Some may have complex or obscure histories, so inclusion here does not necessarily imply that a breed is predominantly or exclusively American.
Cattle breeds fall into two main types, which are regarded as either two closely related species, or two subspecies of one species. Bos indicus (or Bos taurus indicus ) cattle, commonly called zebu, are adapted to hot climates and originated in the tropical parts of the world such as India, Sub-saharan Africa, China, and Southeast Asia.
American bison: 2n = 60; Cattle: 2n = 60; Bovin hybridization is most common in the subtribe Bovina, the most well known of these is the beefalo (a cross between cattle and American bison). Most of these hybrids are deliberate from humans wanting to improve the quality of various cattle breeds (in particular for beef production).
Romosinuano are beef cattle, and are noted for their docile temperament and adaptation to subtropical climates. [2] Romosinuano lines also exist in Costa Rica and Venezuela, [3] and have been imported to the United States for cross-breeding in the hopes of improving cattle production in Florida and similar states.

In the first decades of twentieth century, the favored breed of zebu in Brazil was the Indubrasil or Indo-Brazilian, but from the 1960s onwards, Nelore became the primary breed of cattle in Brazil because of its hardiness, heat-resistance, and because it thrives on poor-quality forage and breeds easily, with the calves rarely requiring human ...
The Brangus is an American hybrid breed of beef cattle derived from cross-breeding of American Angus and Brahman stock. Registered animals have 5/8 Angus and 3/8 Brahman parentage. [3]: 149 A similar hybrid breed, the Australian Brangus, was separately developed in Australia from about 1950. [4]: 138
A breed society, the American Jersey Cattle Club, was formed in 1868. In the USA, a distinction is sometimes made between the "American Jersey", which is comparatively coarse and large and has been selectively bred mainly for milk yield, and the original or "Island" type; [ 1 ] : 212 the latter may also be called "Miniature Jersey".
These cattle are under continuous scientific study because these behavioral traits are suspected to be more environmentally sustainable, especially under the impending threat of climate change, than those exhibited by more traditional breeds as increased exploration, reduced water dependency, and spatial non-constraints by calving mean that ...
