Six spring lambs born Tuesday on a Greytown farm to a single ewe was a one-in-a-million event, says a Massey University lecturer on sheep production.
Dr Lydia Cranston said the successful birth and exceptional survival of the east Fresian lambs - at the Greytown farm of Rex and Pam Saywell on the first day of spring - could be put down to the breed, the optimal body condition of the ewe, and the feed and feeding times.
"I've never heard of that in my lifetime or career. It would be one-in-a-million for sure, pretty dramatic, particularly with the survival."
Dr Cranston said the east Fresian breed was known for its fertility and "with a more fecund breed you can get four or five, which is getting up there, but I think to have six is amazing, especially in New Zealand conditions when they're outside and that".
"I've heard of five before in a straight bred Finn flock, but not six. That is rare," Dr Cranston said.
