Beef + Lamb New Zealand Genetics' Low Input Sheep Progeny Trial is identifying the genetics that will future-proof this country's sheep industry.
The Beltex, or Belgian Texel, has been farmed for about 18 years in the UK, where it is prized for its notably heavy hind-quarters and high meat yield.
Bringing it to New Zealand is the BeltexNZ partnership -- Mount Somers farmer Blair Gallagher, former Invermay head Dr Jock Allison, and farm advisor John Tavendale.
Gallagher says they first looked at bringing the breed here about ten years ago but quarantine and other requirements made it prohibitively expensive. Changed protocols now make it practical, but still expensive.
Imported Beltex embryos and semen have been introduced into the Perendale, Suffolk and Poll Dorset flocks on Gallagher’s Rangiatea farm, near Mount Somers in Mid-Canterbury.
The first lambs were born in early August and Gallagher now has 55 from five different sires. He admits they did not have a “brilliant” take on embryo implantation, achieving only 37% when hoping for 50%.
So they went back to the UK to get more semen and embryos from another three studs – two unrelated sires each – to further spread the genetic base.
“Hopefully we won’t have to go back again because it’s a pretty good way of emptying your bank account,” Gallagher jokes.
He believes that as a meat breed the real potential lies in using Beltex terminal sires through NZ flocks to lift the quality of carcase conformation and meat yield.
While traditional breeds give kill-out percentages of 42 - 43% (Texel achieved closer to 46%), pure Beltex gives up to 58%.
“The half-crosses won’t be as good as the pure-bred, but the poll Dorset or the Suffolk cross will be closer to 52%. So there’s a huge lift in yield and that’s the real potential of the Beltex.”
UK meat companies are prepared to pay a 10-15% premium for Beltex cross lambs, Gallagher told Rural News.
He took 16 animals to the Canterbury Show last week, including four pure-bred Beltex lambs born to surrogate mothers from embryo implants, some AI crossbred lambs and their mothers.
Although the animals were not entered in competition classes, Gallagher expected the display at the show to attract a lot of interest.
The Beltex is believed to be the first new sheep breed brought to New Zealand since the Charollais about a decade ago.
“It’s a million-dollar project over two years, but I can see real benefits for the greater NZ sheep industry. There’s a huge amount of interest in what we’re doing.”
