The Discovery Project helps breeders develop top cow families and breed bulls for the AI industry.
A joint venture between Holstein Friesian NZ and LIC is going strong 18 years after it was established with another six Holstein Friesian bulls being accepted into the LIC Sire Proving Scheme for the 2022-23 season.
The Discovery Project, which genomically screens up to 300 of New Zealand's best Holstein Friesian heifers every year, aims to support the opportunity for breeders to develop top cow families and breed bulls for the AI industry.
Using advanced breeding technologies such as genomic testing, Embryo Transfer (ET) and In-vitro Embryo Production (IVP), the Discovery Project selects the best heifers of potential bull-dam standard early on in their lives, allowing all breeders the opportunity to have their pedigree Holstein Friesian bulls recognised by the industry.
Between 2013-2020, Discovery Project teams have delivered a total of 73 sires into LIC's Sire Proving Programme, with five of these sires going on to graduate into LIC's Premier Sires teams and be marketed.
Discovery Project Committee Chair Wayne Taylor says pre-2004, HFNZ was able to nominate five pedigree Holstein Friesian bulls annually to enter the LIC Sire Proving Scheme. One of those bulls was Athol Famous Prefect, the first Holstein Friesian bull to exceed 700,000 lifetime inseminations, and the winner of the Mahoe Trophy in 1985.
Improved technology led to the establishment of the Discovery Project in 2004, identifying top genetic females within a nucleus herd situation.
"With the advent of genomic testing tools, the Discovery Project moved from first-calving two-year-olds to yearling heifers in order to fast-track selection," Wayne says.
"We were able to identify and capture new genetics earlier than ever before."
Wayne says thanks to the Discovery Project, animals that would have been overlooked 10-15 years ago - 'outliers' - are now being selected based on their genomic merit, rather than BW alone.
"It has opened up the field that way," Wayne says. "All members have the opportunity to nominate a heifer, not just the mainstream bull breeders.
"It allows us to make the most of the genetics within our herd book."
Any heifer calves born within the Discovery Project are free from any breeding restricton with LIC and can be nominated and screened in the hope they will be eligible to re-populate the programme.
The Discovery Project has also shown success with contract mating, with a number of Discovery Project heifers from previous years' teams still being contract mated today.
From the 2014 Discovery Project team, Hillview Mega Pea S2F and Tronnoco B Sulana-ET have been consecutively contract mate from 2016-2022; as has MAH HDF Starstruck-ET S3F, from the 2015 team.
From the 2017 team, five cows have been contracted mated consecutively from 2018-2022.
Wayne says these cows are good examples of the Discovery Project presenting opportunities for exceptional cow families to shine.
Six industry organisations, including DairyNZ and the Dairy Companies Association (DCANZ) have signed an agreement with the Ministry for Primary Industries (MPI) to prepare the country for a potential foot and mouth outbreak.

Beef + Lamb New Zealand (B+LNZ) is a funding partner of DAGI (Drench and Grazing Integration), a new digital tool designed to help farmers manage parasites more efficiently and reduce reliance on drenches.
Beef + Lamb New Zealand (B+LNZ), in partnership with the Ministry for Primary Industries (MPI) and other sector organisations, has launched a national survey to understand better the impact of facial eczema (FE) on farmers.
It's common to look at reproductive challenges through the lens of the mating season. If cows aren’t cycling, if submission rates are low, or if too many come up empty, most farmers will dig into their mating programme to figure out what went wrong.
A brilliant result and great news for growers and regional economies. That's how horticulture sector leaders are describing the news that sector exports for the year ended June 30 will reach $8.4 billion - an increase of 19% on last year and is forecast to hit close to $10 billion in 2029.
Funding is proving crucial for predator control despite a broken model reliant on the goodwill of volunteers.
