Holsteins have the highest average milk production (30 litres per day) and the greatest protein content in their milk. They also have a good food conversion ratio (the ability to turn food into milk). It’s no wonder, then, that they make up 90 percent of dairy cows in Canada. Most Holsteins are black and white, but some have a red and white coat. You can often see both sets of colouring in the Dairy Barn at the Canada Agriculture and Food Museum.
