"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.
Results vary between farms, and methods are still being researched as studies have shown contradicting results on stress levels of calves from different methods of weaning. Traditionally beef calves are weaned by abrupt separation, where the calves are separated from their dams and have no contact with each other, or by fence line weaning where ...
A mare may be in heat for 4 to 10 days, followed by approximately 14 days in diestrus. Thus, a cycle may be short, totaling approximately 3 weeks. [21] Horses mate in spring and summer; autumn is a transition time, and anestrus occurs during winter.
The estrous cycle is about 23 days and the gestation period lasts 250 to 260 days. The calves weigh about 21 kg (46 lb) at birth [14] and scramble to their feet within minutes, being able to move with the herd soon afterwards, [33] a fact on which their survival relies. [58] The main predator of the calves is the spotted hyena. The calving peak ...
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 ...
Weanling usually refers to a horse, though can be used with any livestock. [1] Weaner is more commonly used for a weaned lamb, calf or pig. [2] A super weaner is an exceptionally large elephant seal which has been nursing from more than one lactating female and weighs considerably more than its peers at weaning age. [3]
The mother returns to the herd while the calf hides out at some distance from the herd. The female separates herself from the herd for a few hours while she nurses the calf and cleans the calf as it defecates. Weaning starts at 3.5 months, and the young become fully independent around 14 weeks old. [6]
A calf requires approximately 10% of its body weight in milk daily; for a 100 lb (45 kg) calf, this means 10 pounds (4.5 kg) of milk. [1] As the calf grows, the amount of milk it requires begins to exceed the capacity of its mother to produce the milk. [1] A 500 lb (230 kg) calf requires 50 pounds (23 kg) of milk, but a beef cow only produces ...
