Breeding hoggets at eight months of age can improve a ewe’s lifetime productivity.
Smith is a former NZ High Commissioner to London, Speaker of Parliament, trade minister and Massey University scientist.
He told the recent Federated Farmers annual conference that NZ, by holding out on gene editing, is missing an opportunity to deal with climate change and carbon emissions, and to improve pasture species.
Smith says gene editing is a safe process that simply involves slightly altering the best genes in a particular species of animal or plant.
Embracing gene editing is critically important to enable NZ to progress in key primary sector areas, Smith told the conference.
Opposition to gene editing “is based on ignorance, and I don’t mean that in an unkind way, I just mean there’s a lack of understanding.
“People are more fearful of wider genetic modification. This involves taking genes from one species and using them in another one… notably the toad/gene thing, which is the other end of gene technology and a track we don’t need to go down right now.”
Start gene editing now, Smith urged the conference. This is needed now because new pasture species are being researched and gene editing would make them much more efficient.
But it would need doing in the US as it’s banned in NZ. “Our primary industries are suffering financially as a result of this.”
Scientists in NZ must speak up, says Smith. And news media should not just cover people with colourful, flamboyant views, but also talk to respected scientists.
Asked about Smith’s views on gene editing, Agriculture Minister Damien O’Connor urged caution. He says big marketers of NZ meat and dairy told him recently in London that they don’t want products in any way genetically modified.
These companies say NZ has a market advantage in not having GMOs in food. But O’Connor doesn’t rule it out completely for the future, he said.
“Clearly gene editing is incredibly valuable… but we must ask, who are the consumers of our products and what are they looking for? Being non-GMO gives NZ an advantage now but will it in future and what are the trade offs?”
O’Connor says he’s not dismissing the technology but it needs a lot more work and discussion for a final decision.
