Holstein cows produce an average of 3.5% butterfat with an average of 17,000 pounds of fluid milk per year. That would be 595 pounds of butterfat per year. Holsteins are the highest total fluid milk producers, but are on the low side of percent butterfat and percent protein. Even so, if you compare Holsteins to breeds that produce higher butterfat (like Jerseys and Guernseys), the Holstein will produce more total butterfat in a year due to the higher volume of fluid milk that they produce.
A typical Jersey would produce around 15 kg (~4 gal.) of milk per day on good feed and pasture. A typical Jersey cow will produce 5000 kg per year (or 1319 gal per year).
The six main breeds of dairy cows are Holstein, Jersey, Guernsey, Ayrshire, Brown Swiss, and Milking Shorthorn. Holsteins are the most common and can produce around 22,000 to 23,000 pounds of milk per year. Jerseys are known for their high butterfat content and typically yield about 9,000 to 10,000 pounds annually. Other breeds like Guernsey and Brown Swiss produce similar amounts, generally ranging from 14,000 to 18,000 pounds per year.
As of recent estimates, there are approximately 300,000 Jersey cows in New Zealand. This breed is popular for its high butterfat content in milk, making it a valuable asset to the dairy industry. Jersey cows represent a significant portion of the country's overall dairy herd, which consists of around 6.5 million cows in total. The specific numbers can vary year by year due to changes in farming practices and market demand.
