Cow gives birth to second set of triplets

A Queensland cow is milking motherhood to the max.

Muffet has shocked vets and her owners by giving birth to quadruplets - an extremely rare delivery.

And it's not her first time as a multiple mum.

She had already delivered three sets of twins, when she made headlines by giving birth to triplets last year.

"We had a little angus coloured black boy first which we called Mickey, second was the little black girl which we called Minnie, third one was a little Murray grey coloured girl that we called Murray," owner Ian Beck said.

A fourth sibling didn't survive.

The chance of a cow having triplets is around one in 105,000.

Doing it twice in twelve months is almost unheard of.
