Welcome to the World Jersey Cattle Bureau



The first Jerseys were introduced into Argentina in 1905 and were spread throughout the varied climatic zones of the country. In the southern part of Argentina, where the climate is not ideal for dairying, the Jersey has always been the main breed used to produce milk for family use on large ranches. In the early 1980s, Jerseys were introduced into the central, dairying area of the country. Today, Argentina now has approximately 10,000 Jerseys, with a strong breed growth. For many years, the Jersey had the reputation of being a fancy cow, suitable for showing but not a good producer – a concept which has now changed. Many breeders accept the importance of shows for promotion, but on farm, the cattle are bred for production and functional type. With the cows out to pasture most of the time, they need to be able to walk very long distances, with longevity and good udders also very important under these conditions. Today, many dairymen are breeding Holsteins with Jersey semen to gra de up their cattle to “Jersey” status, recognising the commercial advantages of the breed.

The Asociacion Argentina de Criadores de Jersey hosted the 2004 Annual Meeting Tour.

Jerseys graze on alfalfa pastures at San Isidro Labrador Farm, located 30 miles northwest of Buenos Aires, Argentina. The herd of 150 cows was established in 1979 by Maria Carmen S. de Perez Companc with cattle purchased in Uruguay. In 1987, she bought three heifers from The Billings Farm, Woodstock, Vt., the first of many Registered Jerseys imported from North America. Cows receive an 18% protein supplement metered through Alfafeed automatic feeders at the rate of 350 grams per liter of milk produced. Average daily production per cow is 20 liters (45 lbs.) at 4.8% fat and 3.8% protein. A second dairy with 1,200 cows (40% pure Jersey, 40% Jersey-Holstein crossbreds, and 20% Holstein) is located in Carmen de Areco. The Jersey milk is processed into premium ice cream and sold through Munchi’s ice cream parlors. Embryo transfer and in vitro fertilization work is done by Goyaike S.A., a division of the Perez Companc Group. The firm also produces sexed semen for South American markets and is the majority shareholder of U.S.-based Cyagra.
