The Australian Milking Zebu (AMZ) is a composite breed of dairy cattle, developed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia during the mid-1950s. To develop the breed, the CSIRO bred Sahiwal and Red Sindhi cattle from Pakistan with Jersey cattle. Some Illawarra, Guernsey and Friesian genetics were also included. [1] The development of the breed was governed by strict selection for heat tolerance, milk production and cattle tick (Boophilus microplus) resistance to result in the modern AMZ breed.
AMZ cattle have the color, markings and general shape of Jersey cattle, but also show their Sahiwal and Red Sindhi ancestry with their loose skin.
Cows produce approximately 2,700 kg of milk per lactation.
A zebu, sometimes known as indicine cattle or humped cattle, is a species or subspecies of domestic cattle originating in South Asia. Zebu are characterised by a fatty hump on their shoulders, a large dewlap, and sometimes drooping ears. They are well adapted to withstanding high temperatures, and are farmed throughout the tropical countries, both as pure zebu and as hybrids with taurine cattle, the other main type of domestic cattle. Zebu are used as draught and riding animals, dairy cattle, and beef cattle, as well as for byproducts such as hides and dung for fuel and manure. Zebu, namely miniature zebu, are kept as companion animals. In 1999, researchers at Texas A&M University successfully cloned a zebu.
Holstein Friesians are a breed of dairy cattle originating from the Dutch provinces of North Holland and Friesland, and Schleswig-Holstein in Northern Germany. They are known as the world's highest-production dairy animals.
Dairy cattle are female cattle bred for the ability to produce large quantities of milk, from which dairy products are made. Dairy cows generally are of the species Bos taurus.
Ayrshire cattle are a breed of dairy cattle from Ayrshire in southwest Scotland. The adult Ayrshire cow weighs from 450 to 600 kilograms (990–1,320 lb). Ayrshires typically have red and white markings; the red can range from a shade of orange to a dark brown. They are known for their hardiness and their ability to convert grass into milk efficiently. The breed's strengths today are traits of easy calving and longevity.
The Senepol breed of beef cattle was developed on the Caribbean Island of St. Croix. It has long been thought that Senepol originated from crosses between N'Dama cattle, imported in the late 19th century, and Red Poll cattle, but it is actually an admixed breed between a European taurina zebu. The Senepol breed combines characteristics of heat tolerance and insect resistance with the docile nature, good meat, and high milk production of the Red Poll. They are polled, short haired, and colored red, black or brown.
Sahiwal District, formerly known as Montgomery district, is a district in the Punjab province of Pakistan. In 1998, it had a population of 1,843,194 people, 16.27% of which were in urban areas. Since 2008, Sahiwal District, Okara District, and Pakpattan District have comprised the Sahiwal Division. The city of Sahiwal is the capital of the district and the division.

Santa Gertrudis cattle are a tropical beef breed of cattle developed in southern Texas on the King Ranch. They were named for the Spanish land grant where Captain Richard King originally established the King Ranch. This breed was officially recognized by the United States Department of Agriculture in 1940, becoming the first beef breed formed in the United States. The origin given by King Ranch is that it was formed by mating Brahman bulls with Beef Shorthorn cows, with the final composition being about three-eighths Brahman and five-eighths Shorthorn. In 1918, the King Ranch purchased 52 bulls of three-quarters to seven-eighths Bos indicus breeding to mate with 2500 pure-bred Shorthorn cows on the ranch. At this time, the American Brahman breed as such did not exist, nor were purebred Bos indicus cattle available in the United States.
The Gir or Gyr is one of the principal Zebu breeds originating in India. It has been used locally in the improvement of other breeds including the Red Sindhi and the Sahiwal. It was also one of the breeds used in the development of the Brahman breed in North America. In Brazil and other South American countries the Gir is used frequently because, as a Bos indicus breed, it is resistant to hot temperatures and tropical diseases. It is well known for its milk producing qualities and is often bred with Friesian cows to make the Girolando breed.
Danish Red cattle, also known as Red Danish or Red Dane, are a major dairy cattle breed in northern Europe. There are 42,599 pedigree cows in Denmark. They can be used as a beef breed once they finish their useful lifetime.
Butana and Kenana breeds are part of the shorthorned Zebu group of breeds of eastern Africa. What makes them unusual is that they are dairy breeds, unlike other breeds like the Boran, Baggara, Fung, etc. The Butana breed is found to the east of Khartoum in central Sudan, in the Butana region. The Atbarah Research Station of the Sudanese Department of Agriculture in Atbarah has a special mission for preserving and improving the Butana breed. The Kenana breed is found just south of Butana, mainly in the region between the Blue Nile and the White Nile.
Red Sindhi cattle are the most popular of all Zebu dairy breeds. The breed originated in the Sindh province of Pakistan, they are widely kept for milk production across Pakistan, India, Bangladesh, Sri Lanka, and other countries. They have been used for crossbreeding with temperate (European) origin dairy breeds in many countries to combine their tropical adaptations with the higher milk production found in temperate regions. It has been crossed with Jerseys in many places, including India, the United States, Australia, Sri Lanka, etc.
German Black Pied cattle are a breed of dairy cattle that originated in the North Sea coast regions of northern Germany and the Netherlands.
Sahiwal cattle are a breed of zebu cow, named after an area in the Punjab, Pakistan, where the cattle is found.
The Australian Friesian Sahiwal, is an Australian breed of dairy cattle whose development commenced in the 1960s by the Queensland Government. It is a combination of the Sahiwal, a dairy breed of Bos indicus from Pakistan and Holstein breeds, designed for the tropical regions of Australia. Cows produce approximately 3,000 litres of milk per lactation under tropical pasture conditions with a high resistance to heat, humidity, ticks and other parasites.
Jamaica Hope is a dairy breed of cattle originating from Hope Farm in Jamaica.
In Sri Lanka many farmers depend on animal husbandry for their livelihood, but not a large proportion. Therefore, many livestock products have to be imported. The main livestock products in Sri Lanka are milk, meat and eggs. Hides, wools and other products are still not produced within the country. Animal power formerly used in the cultivation of rice and vegetables has been replaced by modern technology to farm lands. However animal husbandry plays an important role in the rural economy for improving the living conditions of farmers in the country.
The Siboney de Cuba is a hybrid breed of cattle optimized for survival in harsh environments. They comprise 5/8 Holstein Friesian and 3/8 Zebu. As such, they are a true hybrid of two species - however, they are fertile.
Being a country that has a largely rural and agriculture-based industry, animal husbandry plays an important role in the economy of Pakistan and is a major source of livelihood for many farmers. It is estimated that there are between 30 and 35 million people in Pakistan's current labour force who are engaged in livestocks. While the agricultural practice is prevalent throughout the entire country, it is more common in the fertile provinces of Punjab and Sindh, which are traditionally the main areas of agriculture and farming activity. In 2020, the livestock industry was contributing 60.6 % to overall agriculture and 11.7 % to the GDP.
Hariana is an Indian Cow breed native to North India, specially in the state of Haryana. They produce about 10 to 15 liters of milk a day, compared to 8.9 liters when cross bred with Holstein Friesian cattle (HS), whereas pure HS can produce 50 liter a day but it is not as disease resistant in the conditions of North India.
