After 1945, European cattle breeding and dairy products became increasingly confined to certain regions due to the development of national infrastructure. This change led to the need to designate some animals for dairy production and others for beef production; previously, milk and beef had been produced from dual-purpose animals.
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.
The Holstein-Friesian was known to be the best dairy cattle breed for temperate region and the Sahiwal was the best dairy cattle breed for tropical areas. [10] As such, with crossbreeding and genetic mixture of both the Sahiwal and Holstein-Friesian, the AFS breed possesses qualities from both cattle to adapt to the tropical climates.
