A female bovine that has not yet had a calf is known as a heifer. An adult female that has had her first calf (or second calf, depending upon regional usage) is called a cow. Steers and heifers can sometimes be colloquially referred to as "cows," especially by non-agricultural people who are not familiar with the appropriate terminology.
A freemartin or free-martin (sometimes martin heifer) is an infertile cow with masculinized behavior and non-functioning ovaries. [1] Phenotypically, the animal appears female, but various aspects of female reproductive development are altered due to acquisition of anti-Müllerian hormone from the male twin. [2]
Mature female cattle are called cows and mature male cattle are bulls. Young female cattle are called heifers, young male cattle are oxen or bullocks, and castrated male cattle are known as steers. Cattle are commonly raised for meat, for dairy products, and for leather. As draft animals, they pull carts and farm implements.
Dairy heifers and cows can only produce milk after having calved. Dairy cows need to produce one calf each year in order to remain in milk production. Heifer (female) calves will nearly always become a replacement dairy cow. Some dairy heifers grow up to be mothers of beef cattle.
Dairy cows are probably not heifers, because they have borne a calf to produce milk. A young female cow is called a heifer. Does that mean that the cow hasn't been artificially or naturally inseminated by a bull, or does it mean that it has never given birth? 140.254.70.33 22:22, 11 August 2017 (UTC)
Once bred, a heifer is pregnant for nine months and, after giving birth, is then considered a cow. During pregnancy, the udder begins to develop further. After calving, a cow will nurse its calf briefly and then typically be milked two to three times daily. Cows produce about 80 pounds of milk per day, though some can produce well over 100 pounds.
Highland cows are known for their gorgeous hair and for their cuteness. If I was going to get a cow, I'd definitely want a Highland cow or two! Their hair also has a special name, and a special job.
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]
