New records for production by Registered Jersey™ cows were established in 2009, the American Jersey Cattle Association (AJCA) announced today.
The official Jersey lactation average increased to 18,498 lbs. milk, 859 lbs. fat, and 666 lbs. protein. On a Cheddar cheese equivalent basis, average yield is 2,248 pounds. All are new category records.
A record 87,911 lactations were processed by the AJCA. This was a gain of 9,687 records (12.4%) over the previous year, and also represents a 22% increase in records processed since 2007.
The lactation average is calculated on a standardized 305-day, twice daily, mature equivalent (m.e.) basis.
The American Jersey Cattle Association, organized in 1868, compiles and maintains animal identification and performance data on Jersey cattle and provides services that support genetic improvement and greater profitability through increasing the value of and demand for Registered Jersey™ cattle and genetics, and Jersey milk and milk products.
