The dairy cow is the land mammal that produces the largest quantity of milk. One cow alone can produce enough milk to fulfill the annual milk of 150 people. Thanks to its digestive system with four stomachs, cows can digest plants that are rich in cellulose, such as the grass in pastures or harvested hay. This is a quality that the human stomach does not have!
The volume of milk produced by the cow depends on its genetic characteristics, race and physical condition. Quebec herds are made up of several dairy races: Holstein, Ayrshire, Brown Swiss, Canadienne, Jersey and a few others. The most productive race, Holstein, makes up over 90% of the Canadian herd.
Milk production also varies according to the quantity and quality of the pastures, hay and grains, soil and plant composition, and weather conditions.
Production is also a question of food management. On modern dairy farms, feeding dairy cattle is an increasingly more sophisticated task to manage. Daily meals are customized according to each animal’s potential, productivity and lactation stage.
Cows are normally fed five or six times a day. In one day, a cow eats over 24 kilograms of food and drinks between 100 and 125 hundred litres of water, which is the equivalent of a bath tub filled to the brim. Cows are milked at least twice a day, in the morning and the evening. A good cow can produce more than 30 litres of milk per day.

The digestive process
The volume of milk produced by a cow depends on its genetic characteristics, breed and physical condition. It can also vary depending on the quantity and quality of pastures, fodder or cereals fed to it. An average Quebec cow produces more than 8,000 litres of milk annually.
Breeding
Artificial insemination is used a lot because it makes it possible to choose the semen from the bull that is most likely to father genetically strong and productive offspring.
Cows breeds
The Brown Swiss, the Ayrshire, the Canadienne, the Holstein, the Jersey are the mains dairy cows.
