Studies on the natural weaning of zebu cattle have shown that cows wean their calves over a 2-week period, but after that, continue to show strong affiliatory behavior with their offspring and preferentially choose them for grooming and as grazing partners for at least 4–5 years. [24]
"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.
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 ]
Beef calves suckle an average of 5 times per day, spending some 46 minutes suckling. There is a diurnal rhythm in suckling, peaking at roughly 6am, 11:30am, and 7pm. [21] Under natural conditions, calves stay with their mother until weaning at 8 to 11 months. Heifer and bull calves are equally attached to their mothers in the first few months ...
Calf (leg), in humans (and other primates), the back portion of the lower leg; Calf or calves may also refer to: Biology and animal byproducts. Veal, meat from calves;
Sale prices for calves sold from a cow–calf operation are subject to fluctuation as part of the cattle cycle of financial markets. [12] The relatively long period it takes a cow–calf operator to build up a beef herd and raise new calves to the desired weight tends to extend the length of such a cycle. [1]

The cloned calf was born 21 years and 5 months after Starbuck's own birth date and just under 2 years after his death (17 September 1998). The calf weighed 54.2 kg at birth and showed the same vital signs as calves produced from regular AI or ET. Starbuck II is derived from frozen fibroblast cells, recovered one month before the death of Starbuck.
