What is the shortest time between twins?
22.976 secondsThe shortest interval between birth of twins (single confinement) is 22.976 seconds, and was achieved by Amanda Dorris (Canada), who gave birth to Emmanuelle and Elodie at 5:21, at Gatineau Hospital, Gatineau, Quebec, Canada on 6 April 2017. Fraternal twins Emmanuelle and Elodie were born prematurely at 35 weeks.
Is it common for cows to have twins?

Can a cow abort one twin?

How many times does a bull mate with a cow?
Because only a few cows come on heat at a time, one bull can mate with more cows in a year. The average is two bulls per 100 cows. A bull will mate with a cow as soon as she comes on heat after calving. A bull will mate with a heifer as soon as she is heavy enough and comes on heat.
Can a cow produce enough milk for twins?
Some cows just don’t have enough milk to support two calves (although for years my dad tried to tell me that most cows could take care of two calves just fine).
