Norwegian red cattle

                    Norwegian Red Cattle
Norwegian Red (Norwegian: Norsk rødt fe) is a breed of dairy cattle developed in Norway since 1935. Since the 1970s, breeders strongly emphasized functional and production traits resulting in excellent production combined with world-leading performance in health and fertility traits. Norwegian Red cows can have either a red and white or black coat and have a high proportion of genetically polled animals.
                        Size and Weight
Production in the best herds exceeds 10,000 kilograms (22,000 lb), with the top cows milking more than 16,000 kilograms (35,000 lb). Growth traits are also included in the index, and young sires for progeny testing have a growth rate of approximately 1.4 kg/day. Fully-grown cows and bulls have a live weight of up to 600 kilograms (1,300 lb) and 1,300 kilograms (2,900 lb) respectively.
Norwegian Red cows have an average height of 137 centimetres (4.49 ft) at the point of withers. The average height for bulls varies greatly, but the average is around 145 centimetres (4.76 ft) tall at the point of withers.
                    Fertility and Health
Fertility was first included in the Norwegian Red breeding program in 1971.The Norwegian Red is likely the most fertile breed of dairy cattle in the world due to the selection of breeding and genetics for increase fertility for more than 40 years.
Calving ease has been included in the selection program since 1978.The Norwegian Red is characterized as a breed with a low frequency of calving difficulties. Less than 2% of the calvings are reported as having major calving difficulties. Stillbirths are also included in the index, and less than 3% of Norwegian Red calves are stillborn.
Health traits have been included in the net merit index since 1978. Currently mastitis and other diseases (in particular ketosis, milk fever, and retained placenta) are included in the breeding program. Although these are low heritability traits, progeny testing based on a high number of daughters provides a selection index with high accuracy. Progeny testing for mastitis is currently based on approximately 300 daughters.
                                 Polled
Norwegian Reds may be either polled or horned. Currently 40% of the calves in Norway are born polled (genetically without horns).Systematic selection of polled sons after polled elite sires during recent years have increased the frequency of polled animals.
