Most beef cattle are mated naturally, whereby a bull is released into a herd of cows approximately 55 days after the calving period, depending on the cows' body condition score (BCS). If it was a cow's first time calving, she will take longer to re-breed by at least 10 days. [4]
The Black Hereford is a crossbreed of beef cattle produced in Britain and Ireland with Hereford beef bulls with Holstein-Friesian dairy cows. Black Herefords are not usually maintained from generation to generation, but are constantly produced as a byproduct of dairy farming as a terminal cross. They are one of the most common types of beef ...
Other than the few bulls needed for breeding, the vast majority of male cattle are castrated as calves and are used as oxen or slaughtered for meat before the age of three years. Thus, in a pastured herd, any calves or herd bulls usually are clearly distinguishable from the cows due to distinctively different sizes and clear anatomical differences.
They may have a few herd bulls and utilize natural mating, but may have no bulls and rely primarily on artificial insemination. [6] Cattle from a cow–calf operation may be sold after they have been weaned to be matured elsewhere, such as at a feedlot, or may be raised to near-slaughter weight and sold at the age of 1–2 years.

The Murray Grey breed was developed from an initial chance mating of a black Aberdeen Angus bull and a roan Shorthorn cow in 1905 during the Federation drought.The resulting 13 dun-grey calves from these matings were kept as curiosities and then bred on the Thologolong property along the Murray River in New South Wales by Peter and Ena Sutherland.
Calving (step by step) "Calf" is the term used from birth to weaning, when it becomes known as a weaner or weaner calf, though in some areas the term "calf" may be used until the animal is a yearling. The birth of a calf is known as calving. A calf that has lost its mother is an orphan calf, also known as a poddy or poddy-calf in British.

Cow with calf (standing behind her, parts of its body creating the illusion of supernumerary teats "on" the mother). The cattle are generally small, with weights in the range 360–550 kg (800–1200 lb) for bulls and 270–360 kg (600–800 lb) for cows; in the past there was a still smaller or dwarf type within the breed, known as the Guinea, which weighed about 230 kg (500 lb) or less.
