Dairy breeds
Holstein Friesian, Jersey, Gir, Sahiwal and Red Sindhi: bred first of all for milk.
Dairy breeds are bred first of all for milk. A good dairy cow turns grass, fodder and grain into milk rather than muscle, so she tends to be lean and angular, with a large, well-attached udder and a long working life in the parlour. The Holstein Friesian dominates high-yield herds across the world, while Jersey, Guernsey and Ayrshire are kept for richer milk. In South Asia, Gir, Sahiwal, Red Sindhi and Rathi are the great milking zebu, valued for milk in heat that would trouble most European cows.
What makes a dairy cow
Breeders of dairy cattle select for yield, for the fat and protein in the milk, for an udder that holds up over many lactations, and for fertility, since a cow must calve to milk. The type is often called angular or wedge-shaped: fine bone, little flesh over the ribs, a deep body for a large rumen. Milk recording, where each cow's yield is weighed and sampled every month, began in Denmark in the 1890s and spread through the dairy world. It is the backbone of modern breeding, joined in recent decades by genomic testing of young bulls.
The black-and-white world
The Holstein Friesian came from the lowlands of North Holland and Friesland and was developed for very high yields in North America. It is now the most numerous dairy breed in the world, and in many countries most of the national herd is Holstein or Holstein-cross. Its milk is plentiful and comparatively low in fat. The Jersey, a small fawn cow from the Channel Island of the same name, gives less milk with much more butterfat, and the Brown Swiss, Ayrshire, Guernsey and the red breeds of Scandinavia fill the space between.
The milking zebu of South Asia
India is the largest milk producer in the world, and its own breeds are a large part of the story. Gir from the hills of Saurashtra, Sahiwal from the Punjab, Red Sindhi from Sindh and Rathi from the Bikaner country of Rajasthan are the best-known milking zebu. They give less milk than a Holstein in a cool climate, but they cope with heat, ticks and poor feed. Gir and Sahiwal went abroad to found dairy herds in Brazil, Kenya, Australia and the Caribbean, and Gir is a parent of Brazil's Girolando.
Crosses and the tropics
Across the tropics, dairy farmers have long crossed European bulls onto local zebu cows to combine yield with hardiness. India's Karan Fries and Frieswal, Brazil's Girolando, the Australian Milking Zebu and the Jamaica Hope were all bred this way. The balance is delicate: too much European blood and the cow struggles in the heat, too little and the yield falls. In India, national programmes now also support pure indigenous breeds, alongside crossbreds, to keep the native lines in use.

Good to know
- A dairy cow needs to be milked on a steady schedule, usually twice a day, every day of her lactation.
- High-yielding cows need more feed and water than their size suggests; a lactating cow can drink well over 50 litres a day.
- Shade and water matter in hot weather, even for heat-tolerant zebu.
- Most cows are dried off for six to eight weeks before the next calf.
