The following is a list of breeds of cattle. Over 800 breeds of cattle are recognized worldwide, some of which adapted to the local climate, others which were bred by humans for specialized uses. Breeds fall into two main types, regarded as either two closely related species, or two subspecies of one species. Bos indicus (or Bos taurus indicus) cattle, also called zebu, are adapted to hot climates. Bos taurus (or Bos taurus taurus) are the typical cattle of Europe, north-eastern Asia, and parts of Africa – they are referred to in this list as "taurine" cattle, and many are adapted to cooler climates. Taurus/indicus hybrids are widely bred in many warmer regions, combining characteristics of both the ancestral types (such as the Sanga cattle of Africa). In some parts of the world further species of cattle are found (both as wild and domesticated animals), and some of these are related so closely to taurine and indicus cattle that interspecies hybrids have been bred. Examples include the Dwarf Lulu cattle of the mountains of Nepal with yak blood, the Beefalo of North America with bison genes, theSelembu breed of India and Bhutan with gayal genes. The Madura breed of Indonesia may have banteng in its parentage. The Dzo of Nepal is an infertile cattle-yak crossing which is bred for agricultural work. Like the mule which is also infertile, they have to be continually bred from the parent species.
Sahiwal
The Sahiwal originated in the dry Punjab region which lies along the Indian-Pakistani border. They were once kept in large herd by professional herdsmen called "Junglies". However with the introduction of irrigation to the region they began to be kept in smaller numbers by the farmers of the region, who used them as draft and dairy animals.The Sahiwal is one of the best dairy breeds in India and Pakistan. It is tick-resistant, heat-tolerant and noted for its high resistance to parasites, both internal and external. Cows average 2270 kg of milk during a lactation while suckling a calf and much higher milk yields have been recorded. Due to their heat tolerance and high milk production they have been exported to other Asian countries as well as Africa and the Caribbean. As oxen they are generally docile and lethargic, making them more useful for slow work.
Their color can range from reddish brown through to the more predominant red, with varying amounts of white on the neck, and the underline. In males the color darkens towards the extremities, such as the head, legs and tails.
The Sahiwal in Australia
Sahiwal arrived in Australia via New Guinea in the early 1950’s. In Australia, the Sahiwal was initially selected as a dual-purpose breed. It played a valuable role in the development of the two Australian tropical dairy breeds, the Australian Milking Zebu and the Australian Fresian Sahiwal. Sahiwals are now predominately used in Australia for beef production, as crossing high grade Sahiwal sires with Bos taurus animals produced a carcass of lean quality with desirable fat cover.
The Sahiwal is the heaviest milker of all Zebu breeds and display a well developed udder. Sahiwals demonstrate the ability to sire small, fast-growing calves and are noted for their hardiness under unfavorable climatic conditions.
