Holstein-Friesian Cattle - an overview | ScienceDirect TopicsThe Holstein-Friesian is the largest of the dairy breeds; it produces the largest amount of milk and is the most popular. The breed has its origin in the northern provinces of North Holland and West Friesland of the Netherlands. In the early stages, the cattle were either black and white or red and white.

Influence of bull age, ejaculate number, and season of -- &#; The study involved the interrogation of a large dataset collected over a -yr period, (n = , ejaculates; n = Holstein Friesian bulls aged between mo and yr). Bulls aged less than yr had the poorest semen production and sperm motility values for all parameters assessed compared with bulls older than yr (P < .).

Six Characteristics That Make Holstein Friesian CattleThe average weight of a Friesian cow is around kg at full maturity, reaching the same frame-size and weight as pure Holsteins. Historical records show that some Friesian beef cattle actually reached over . tonnes in finishing weight. Herd protein levels of around .% are often reported, making them an attractive breed for many dairy farmers.
Holstein Friesian Cattle - History, Characteristics and The milk of this Holstein Friesian breed has high fat and protein content. An average of .% butterfat and .% of protein are usual components of this milk, and there might be slight variations owing to the changes in climate and fodder. An adult Holstein Friesian cow can weigh between - kilograms and measure a height of about - cm.

Temperament of Holstein/Friesian bulls | Keeping A Family -- &#; Hi all We have about dairy cows we use to feed the lambs from our sheep dairy, I'm really sick of hunting down replacement cows paying heaps and getting rubbish, I'm also sick of carting cows to dairy bulls or using unsuccessful AI. So I think it's time to get a dairy bull to breed our own replacements, I've already crossed off jersey bulls due to
