I've read a lot of articles, and heard a lot of people answer this question with a "Yes" but, we've had a number of twins over the years, and I can't think of single cow who twinned more than once.
Do you consider twins to be desirable or undesirable? And why?

This is natural twinning - and some rare cows have twins regularly in their lives. So there is a genetic ability here. Twinning in cows is not very strongly inherited we think as their daughters don't regularly produce twins. So it's been very hard to breed for a twinning herd although there is one at Ruakura which is making slow progress. Dr Chris Morris has collected twinning cows from all over New Zealand and he has made positive but slow progress.

Twins in cattle are not common- about 1 set in every 4000 births.
If a cow has twins, is she more likely to have another set of twins then any other cow?
