Ubre Blanca with Fidel Castro. Ubre Blanca (c. 1972–1985) was a cow in Cuba known for her prodigious milk production. The cow, along with the "Cordón de La Habana" coffee plantations, the Voisin pasture system, and the microjet irrigation system, symbolized Fidel Castro's efforts to modernize Cuba's agricultural economy.
The production of milk requires that the cow be in lactation, which is a result of the cow having given birth to a calf. The cycle of insemination, pregnancy, parturition, and lactation, followed by a "dry" period of about two months of forty-five to fifty days, before calving which allows udder tissue to regenerate.
Use of milk production hormone, recombinant bST: A study in February 1999 determined the "response to bST over a 305-day lactation equaled 894 kg of milk, 27 kg of fat, and 31 kg of protein". [19] Monsanto Company estimates a figure of about 1.5 million of 9 million dairy cows are being treated with rBST, or about 17% of cows nationally.
The top breed of dairy cow within Canada's national herd category is Holstein, taking up 93% of the dairy cow population, have a production rate of 10,257 kilograms (22,613 lb) of milk per cow that contains 3.9% butter fat and 3.2% protein [8]
The lowest average production was in New Zealand at 3,974 kg (8,761 lb) per cow. The milk yield per cow depended on production systems, nutrition of the cows, and only to a minor extent different genetic potential of the animals. What the cow ate made the most impact on the production obtained.
Terminology differs between countries. In the United States, for example, an entire dairy farm is commonly called a "dairy".The building or farm area where milk is harvested from the cow is often called a "milking parlor" or "parlor", except in the case of smaller dairies, where cows are often put on pasture, and usually milked in "stanchion barns".
It is a dual-purpose breed, used both for draught work and for milk production. From about 1870 onwards, Kankrej bulls and cows were exported to Brazil, where they were used to create the Guzerá breed, [2]: 193 which was later among the breeds from which the American Brahman developed. [2]: 137
