Twins and fertility

[som farmer]

I guess cows aren't really ideally built for twins? How many people have seen twins born naturally and without incident vs the ratio of those that required assistance?

Sheep seem to have a multiple offspring survival tactic to try and offset the fact that where they lived originally resources would have been scarce at times, plus everything with eyes and a mouth wanted to eat them. Plus the natural law of sheep mortality having an influence.

helped very few, they are usually smaller. Sheep have 2 tits, and twin easily, cows have 4, and few twins, seems it should be, the other way round. Cows with a twin, usually end up with some small problem, RFM, DA, slow getting back i/c etc.

Had a heifer bulling, put hand in to serve and nothing there to grab hold of. Thought I must be wrong with the heat. 3 weeks later bulling again. Got vet to check, she had one ovary, and nothing else!
