An expenditure of 150 kJ produces approximately 62.5 calories of heat.
59.711 kilo calories of heat are produced from 250 kilojoules. 5 kilojoules are equivalent to 1 kilo calorie of heat.
That really depends on the breed of the heifer and her age. At the most she should be around 24 months of age when she calves. Brahman and Brahman-influenced heifers should be a few months older. Weight really isn't a factor in this type of question.
Yes
Semen that is ejaculated into cows to produce Angus-sired calves.
50% of the calf traits come from the Bull.
Bull calves.
There is no such thing. Bull calves are male, never either male or female. Female calves are called heifer calves.
Do you mean, "How many other calves are delivered at the same time as a young bull?" Either zero or one, usually.
Bull calves, steer calves, cows and heifers.
Yes.
A cow is a mature female bovine that has already had at least two calves. A bull is a male bovine that is used to breed cows. Therefore, a bull mates with a cow to produce a calf that has a 50% chance of growing into a cow or a bull.
A cow can have anywhere from one to 20 calves in her lifetime, depending on how productive she is and how long she is able to stay in the herd to produce those calves. On average, a cow will produce eight calves in her lifetime. Cows that are used for embryo transfer can produce up to twice as many calves in her life time than she can by her own doing. The record number of calves a cow has had in her lifetime is 39.
Baby calves.
Bull calves are altered or castrated, at which time they are called steers. Steering a bull prevents fighting, accidental breeding with cows and heifer calves, and allows for easier management.
Depends on where you live and the prices themselves. Dairy bull calves will not cost much; maybe $150-$200. You won't find beef bull calves for sale. Make sure you castrate them as soon as possible so you don't have a trainwreck when they get older.
