The American Jersey Cattle Association (AJCA) announced that new records for production by Registered Jersey cows were established in 2010.
The official Jersey lactation average increased to 18,567 lbs. milk, 876 lbs. fat, and 671 lbs. protein. On a Cheddar cheese equivalent basis, average yield is 2,270 pounds. All are new category records.
A record 88,727 lactations were processed by the AJCA, an increase of 23% in five years.
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.
