Yes cows can have twins but theres a lower chace of survival.
No. Twins are determined by the cow herself, not the bull. It's still unclear as to what causes the act of twinning, even in humans.
A female mammal causes twins.
1/1000 births = 0.001% of calves are born as twins.
There is no such thing as a 2 headed cow!!
Not very often. It is more common for a cow to have twins than triplets: triplets occur maybe 1:100,000 births. A cow will have twins 1:1000 births.
A pair of 1900 lb. twins.
It's possible, but a very rare coincidence.
Whether the dam was a twin herself may have a little influence on her odds of giving birth to twins. Normally twins occur in one out of 1000 births.
Not very often. Twins are usually 1 in 1000 births, and twins from the same cow 2 years in a row, even more rare!
A cow will only calve once a year, and only give birth to one calf (twins 1:1000 births) at a time.
Only if the twin is a heifer and if that twin has been tested negative for being a freemartin (IF she had been twinned with a bull calf). Twin heifers are both highly likely to get pregnant when they reach puberty.
A cow typically has one calf per year. They have a gestation period of 9 months, and usually have just one calf although they are known to have twins.
