Strategic breeding drives dairy success
Krystle Bennett and Nigel Brinkworth have developed their Walton farm into a model of sustainable, modern dairy farming.
Nigel, a third-generation farmer, has worked with his wife Krystle to expand and evolve their operation, with strategic breeding playing a pivotal role in their success.
“We’ve been very deliberate about the genetics we bring onto the farm,” says Krystle. “It’s not just about production; it’s about building cows that thrive in our unique system.”
Two years ago, the couple purchased a 100-hectare farm adjacent to their original 120-hectare property, now linked by a newly built bridge. By next season, the combined 220-hectare farm will support a herd of around 600 cows.
For the last eight years, their herd has been predominantly sired by CRV bulls, with a strong focus on traits suited to their 3-in-2 milking schedule. “Capacity, udders, and rump width are non-negotiables,” says Krystle, who works closely with their CRV sales consultant, Mark Whelan, to fine-tune her breeding choices. With a target of reaching 500 kg milk solids (MS) per cow, these attributes are key to ensuring long-term production and herd health.
The couple is particularly drawn to CRV’s approach to breeding cows with solid, functional frames rather than just focusing on the numbers alone. “CRV seems to prioritise the cow rather than just the figures, and we’re happy with the results,” Krystle adds.
The Brinkworths operate a splitcalving system, with autumn calving in one shed and spring in the other.
“We’ve been very deliberate about the genetics we bring onto the farm,” Krystle Bennett
This allows them to achieve premium winter milk while minimizing stress on their cows and staff. “Autumn calving means our cows avoid the harsh spring weather during late pregnancy,” says Krystle.
This season, they’ve introduced sexed semen through CRV’s Accelerate pack, which includes 20 percent sexed semen, to get top quality replacements. They are careful with how sexed semen is used, putting systems in place to ensure it is used on the right animals at the right time.
“Only the top performing cows make the breeding list for sexed semen and only those on their second or subsequent heat,” says Krystle.
In addition to production traits, the Brinkworths are dedicated to incorporating polled genetics to improve animal welfare. “I like the idea of not dehorning, but I don’t want it to be the only reason I pick a bull; it has to come with other valuable traits,” says Krystle.
This year, they are using three polled bulls, including Gym, the first homozygous polled bull to make New Zealand’s prestigious Ranking of Active Sires (RAS) list .
“It’s nice to see the polled bulls starting to get some decent figures as well, and being recognized on the RAS list,” says Krystle.
Their commitment to sustainable, highquality dairy farming and investment in genetics that suit their system has enabled the Brinkworths to create a herd that’s not only productive but aligned with their goals.

Making complex breeding decisions simple
A complex Canterbury dairy farming operation has developed a simple breeding ethos with the help of CRV to drive productivity and sustainability.
They are part of a growing number of farmers who are using CRV’s sexed semen.
Their advice to other farmers: Use sexed semen on your best cows to breed the herd you want faster and use beef semen on the balance of your herd to produce a high-value dairy-beef calf.
Arjan Van’t Klooster, his wife Kelsi, and two boys Kees and Finn farm 3,500 cows across three dairy farms near Glenavy in Canterbury, supplying Fonterra. They share milk 1,450 cows on one 360-ha farm, own a herd of 950 cows milked on a 270-ha platform, and have share milkers milking the third herd of 1350 cows on another 360-ha property.
For the first three weeks of mating, they artificially inseminate about 60 percent of the total herd with sexed semen, choosing their bestproducing cows and heifers that meet their type requirements for breeding
replacements. They then use dairy beef semen, transitioning to Wagyu, and finally a short gestation beef on the balance of the herd. The total mating period takes about nine weeks.
He says they have been maintaining and improving production each year, even as they have seen their cow size reduce to around 550kgs.
“We’ve done a few things on the farms as we have looked to drive efficiency. But in terms of maintaining and growing our production, I would put that purely down to the genetics we’re getting from CRV.”
Arjan says they have no real concerns about their in-calf rate using sexed semen. They use cow collars on all the herds, except their heifers where they use Estrotect™ breeding indicators.
“The collars and Estrotect patches have been great for clearly identifying cows and heifers in heat and ready for mating,” says Arjan.
“We focus on the efficiency and fertility of our herd to minimise waste on our system and that’s a big driver for using sexed semen. We can drive that genetic gain in our herds by using specific bulls for our top genetic cows and heifers so we can be assured of no bobbies.”
“Overall, our experience with CRV has been excellent. CRV is playing a crucial role in driving genetic improvement across our herds and ultimately contributing to our farms’ success.”

Breeding the best for your farm
CRV’s breeding
Breeding programme selection process
Selection of parents
CRV starts by selecting superior parent animals based on their genetic merit for specific traits. At CRV we focus on traits that lift the overall health and efficiency of the animal. 1.
Breeding
A calf is created via:
Recording births and DNA testing
After the calf is born, detailed records are captured on herd recording software for each individual animal. These calves are also DNA tested.
Selection of Progeny
Validating information
Embryo transfer programme
An embryo is created from the elite genetics and then implanted into a cow.
Seasonal contract mating
Cows are identified through data from the NZAEL national database (DIGAD). They are then mated to an optimal sire. 2.
Using genomics, CRV selects options for their breeding programme – both females and males. The heifers can be selected as donors and the males are options for the market.
The males selected for market are then distributed to Info Herd farmers. Resulting heifer calves are genotyped (DNA tested) and once they are milking, the phenotypic data (physical attributes such as milk production, and conformation traits) are measured.
Producing results from the best
Selected bulls are housed at CRV’s purpose- built facility in the Waikato which includes cattle yards, animal housing, collection area, semen processing facility and distributions centres.

Breeding programme highlights
First homozygous polled bull on the RAS list
Last year CRV produced the first homozygous polled bull (Gym) to make New Zealand’s prestigious Ranking of Active Sires (RAS) list demonstrating the strides CRV is making in breeding top-quality polled bulls. CRV’s catalogue now features 27 polled bulls across the main breeds Friesian, Jersey, and Crossbred, nearly tripling the options available from four years ago.
CRV has made a significant investment in its polled breeding programmes internationally across Holland and the USA. That work, combined with CRV’s efforts in New Zealand is providing farmers with high-quality polled bull options to choose from.
Facial eczema tolerance
FE tolerant sires provide an effective way to increase your herd’s tolerance to FE challenges, resulting in healthier cows and improved production.
Genomic selection results in award-winner
A Northland-bred Jersey bull (Sherlock) won JerseyNZ’s JT Twaites Sire of the Season award, a prestigious national award that recognises sires who have the potential to significantly influence the quality of cows within dairy herds across New Zealand.
The selection of Sherlock’s sire is an example of using genomic testing to select the best.
Using genomics, we can strategically combine desirable traits and minimise the transmission of undesirable genetic factors. That means we can improve the overall quality of the bull’s progeny.

Sexed semen instrumental in business gains
Manawatu farmers, Steve and Vera Shailer are coming into their fourth season using CRV’s sexed semen and their first crop of heifers from sexed straws have entered the milking herd.
The Shailers have been with CRV for seven years and were sharemilkers before stepping into farm ownership where they currently milk 500 cows across 210ha with a 180ha runoff.
“We started using sexed semen when we transitioned to our own farm, and it’s been instrumental in guaranteeing us replacements to optimise our breeding strategy,” says Steve.
By allocating 100 straws to sexed semen, the Shailers ensure around a 26 percent replacement rate.
“Using sexed semen helps us guarantee the number of replacements we’re getting and helps us accelerate our breeding goals,” says Steve.
Steve says they have also seen very little difference in their empty rate
using sexed semen.
“In terms of conception rates, we’ve found minimal difference between conventional and sexed semen. We do have strict protocols to ensure we pick the most eligible cows for breeding and only use sexed semen on cows in their second or third heat that are displaying strong physical signs.”
“Using CRV’s sexed semen has been a smart investment for us. It aligns with our breeding goals and ensures a more sustainable and efficient approach to our herd management,” says Steve.
Advice on using sexed
Get advice on which cows to use sexed semen, based on your breeding goals. At CRV we’re focussed on supporting you from product selection through to management. To get you started, here are some tips for selecting the right animal.
Accelerate genetic gains with smart cow selection
Targeting the best cows in your herd is key to maximising genetic improvement with sexed semen. Here’s how to craft a winning strategy:
⊲ Start with the top 25% based on NZMI, PW, or BW
⊲ Focus on early calvers for better recovery
⊲ Prioritise younger, wellconditioned cows for higher fertility
⊲ Exclude high-risk cows with health issues
⊲ Plan for flexibility with more cows than needed
Perfect your heat detection
Timing is critical with sexed semen. Get the best results by inseminating 18-24 hours after heat begins. Here’s how:
⊲ Start heat detection 5 weeks before mating
⊲ Use reliable aids like CRV’s Estrotect™ patches
⊲ Assign a dedicated heat detection lead
Precision on insemination day
Insemination day is crucial - here’s how to get it right:
⊲ Use different coloured aids for different semen types
⊲ Make cow-side decisions based on heat intensity
⊲ Handle sexed semen with care

CHANGUS
The strength of the Changus breed lies in its unique combination of traits: the Angus’ calving ease, shorter gestation, and superior marbling, paired with the Charolais’ exceptional growth and carcass yield. Kakahu Changus brings together Kakahu’s top Angus and Charolais genetics, enhanced by the added benefit of being homozygous polled.
This year’s Changus bulls are sired by Kakahu Milestone, a proven Charolais bull excelling in the Beef + Lamb NZ Progeny Test. Milestone ranks in the top 5% for calving ease and the top 1% for 400-day weight and gestation length, according to the Charolais BREEDPLAN (December 2024).
Kakahu has a strong history in dairy genetics and has spent several years refining this new breed. Feedback from a select group of dairy farmers has been overwhelmingly positive, highlighting Changus bulls as an excellent choice for easier calving, strong calf performance for rearers, and well-grown cattle for finishers.
Changus calves exhibit solid coat colours ranging from dark grey to cream. While less uniform than purebred Charolais, their distinct colouring makes them easy to identify, even among crossbred herds.

Johnny Higgins –dairy farmer, Cambridge
Success in farming often lies in the details, and for Johnny Higgins, CRV’s herd testing service delivers the precise insights needed to improve herd performance and health.
Johnny tests three times a year, gaining regular, accurate data that has become a cornerstone of his management strategy. From improving genetics to enhancing milk quality, CRV’s herd testing helps Johnny achieve tangible results.
“Herd testing with CRV is so easy,” Johnny shares. “We’ve got
experienced people like Shay [herd tester] who come in and take care of the testing for us. It doesn’t even feel like it’s much more work than a normal milking—you just cruise through it.”
For Johnny, the benefits are clear:
Lower SCC: Maintain high milk quality and reduce mastitis risk.
Better breeding: Identify and breed top-performing cows for long-term herd improvement.
“Our main reason for herd testing is to improve genetics and milk quality,” Johnny explains. “Lowering our cell count and breeding better cows are the big drivers for us, and herd testing plays a key role in helping us achieve that.”
Improve milk quality: detect mastitis early (via SCC) and optimize fat and protein levels.

SireMatch analyses the breed make-up of your herd and can sort the breed information of your cows into separate groups. As a result, you can mate specific bulls to specific breeds of cows in your herd, for example:
Your group of Friesian cows to Jersey bulls
Your group of Jersey cows to Friesian bulls
Your group of Crossbred cows to both Jersey, Friesian and Crossbred bulls

Optimise timing for more calves
ESTROTECT™ Breeding Indicators feature breeding patch technology that indicates when cows are ready to breed, helps confirm pregnancies and provides pinpoint timing for AI protocols.
When activated the precision designed Breeding Patch indicates when cows are in optimal estrus to be bred.
Third-party research has shown that when the breeding patch (or equivalent surface area) is rubbed off, confirmed pregnancy rates can be increased by up to three times!
Meanwhile, a study by the University of Arkansas (U.S.) determined ESTROTECT™ Breeding Indicators were 86% accurate in identifying non-cycling heifers prior to breeding.
ü Know when it’s time to breed with the Breeding Patch.
ü Easy to use, self-adhesive
ü Stays in place in rain, snow or heat.
