It depends on what it eats and his physical condition
Depends on the breed and the birth weight of the calf. Some cows can stand as tall as only 2 feet at the shoulder; some are as big as 3.5 feet at the shoulder.
What breed is the cow? What size is the calf? How old is the calf? These are all factors that determine whether the calf is full enough drinking from two quarters, or whether the other two quarters may be infected with mastitis and the cow won't let the calf suckle the other two quarters; or the calf's just a newborn and/or is a small calf, and the cow is producing too much milk for such a small calf.
Yes,there is a two headed calf.
By two years old a child's brain is approximately 25% of its adult weight.
22 months
There is no such weight. Cows are mature female bovines that have had at least one or two calves. If you are asking about a calf, that's a different question altogether.
Female belugas typically give birth to one calf every three years. Gestation lasts 12 to 14.5 months. Newborns are about 1.5 metres (4.9 ft) long, weigh about 80 kilograms (180 lb), and are grey in color. The calves remain dependent on their mothers for at least two years.
The calves are preyed upon by by lions and spotted hyenas. A calf can follow its mother only three hours after birth. A rhino calf stays with its mother until it is about two to four years old, when she has her next calf. The mother always leads the calf and will defend it unhesitatingly against actual and potential danger. A calf starts browsing at about three months but will not be completely weaned for about another nine months. Until it is two to four years old it will stay with its mother, by which time she is pregnant again. The mother vigorously repels a calf that stays around until the birth of its sibling.
Most producers would call her a free-loader or a cull cow. If she can only produce a calf once ever two years, she shouldn't even be used as a brood cow in the first place. A cow should produce a calf EVERY year, not every two years. That's a waste of money and feed to be looking after a cow that apparently has terrible fertility and trouble breeding back.
Elephant calves suckle milk from their mother for about the first two years, then move on to eating vegetation.
A calf with only four teeth is a newborn calf, or one that is just a day or two old.
Assuming you are referring to a cow that is 20 years old, then the answer to this question would be around 18 calves, if she's never had twins in her life. This is because it takes two years for a female, from birth to her first parturition, to grow old enough to produce a calf. After she has had her first calf she is able to produce an average of one calf per year. The number may be higher if she has had twins in her lifetime.
