Said to be a one in 100,000 chance of happening — though no-one really knows the odds — the three identical creatures all appeared on Thursday night.
Farmer Doug Dodds said he was surprised to see them all and at first thought some other newborn had walked over after birth and twins became triplets.
"But we had a look around and the only other mother due to give birth hadn’t yet, she came later, so it was triplets," Mr Dodds said.
"She did it all herself. I didn’t pick her as having triplets. Usually they are in a bit poorer condition but she looked all right.
"She is not fussed about it. Just carries on."
The triplets were doing well and appeared to be in rude good health, Mr Dodds said.
Being bulls, they normally would be facing a grim future but he was likely to hang on to them for a while yet and see how they developed.
He ran a Friesian stud at Middlevale Farm, and it would be good for the stud to see how they developed, he said.
The farm had been in the family since 1911 and the stud could be traced back to 1912.
The odds were reported to be one in 100,000 of it happening.
But Mr Dodds said the odds might be somewhat smaller.
"In those big herds of thousands, triplets may get born but no-one notices as they get lost in the herd straight away. So it is hard to tell how many triplets there are out there."
