The Holstein Friesian is an international breed or group of breeds of dairy cattle. It originated in the Dutch provinces of North Holland and Friesland and in Schleswig-Holstein in northern Germany. It is the dominant breed in industrial dairy farming worldwide, and is found in more than 160 countries. It is known by many names, among them Holstein, Friesian and Black and White.
Biological Nomenclature: Bos primigenius taurus
Holsteins have distinctive markings, usually black and white or red and white in colour, typically exhibiting piebald patterns. On rare occasions, some have both black and red colouring with white. The red factor causes this unique colouring. 'Blue' is also a known colour. This colour is produced by white hairs mixed with the black hairs giving the cow a bluish tint. This colouring is also known as 'blue roan' in some farm circles. They are famed for their high dairy production, averaging 22,530 pounds (10,220 kg) of milk per year. Of this milk, 858 pounds (3.7%) are butterfat and 719 pounds (3.1%) are protein.
A healthy calf weighs 40 to 50 kg (75–110 lb) or more at birth. A mature Holstein cow typically weighs 680–770 kg (1500–1700 lb), and stands 145–165 cm (58–65 in) tall at the shoulder. Holstein heifers should be bred by 11 to 14 months of age, when they weigh 317–340 kg (700–750 lb) or 55% of adult weight. Generally, breeders plan for Holstein heifers to calve for the first time between 21 and 24 months of age and 80% of adult body weight. The gestation period is about nine and a half months.
Use:
Dairy farming is a class of agriculture for the long-term production of milk, which is processed (either on the farm or at a dairy plant, either of which may be called a dairy) for the eventual sale of a dairy product.
The 2008 average actual production for all USA Holstein herds that were enrolled in production-testing programs and eligible for genetic evaluations was 23,022 pounds (10,443 kg) of milk, 840 pounds (380 kg) of butterfat, and 709 pounds (322 kg) of protein per year. Total lifetime productivity can be inferred from the average lifetime of US cows. This has been decreasing regularly in recent years and now stands at around 2.75 lactations, which when multiplied by average lactation yield above gives around 61,729 pounds (28,000 kg) of milk.
The current national Holstein milk production leader is Bur-Wall Buckeye Gigi EX-94 3E, which produced 74,650 pounds (33,860 kg) of milk in 365 days, completing her record in 2016.
The considerable advantage, compared to the UK, for example, can be explained by several factors:
