Flexible Milking, John Totty (Canterbury)
22 min read
John Totty switched to a 10-in-7 milking routine, reaping benefits for his cows and staff. This flexible method, which he learned about from DairyNZ's scientist Paul Edwards, suits his Jersey herd in the Canterbury foothills. It enhances profitability via improved health, reproductive results, and staff retention, with minor production decline. After its 2020/21 launch, he saw a 10% rise in the 6-week in-calf rate, shorter mating durations, and hired quality staff amid shortages. This also granted him more managerial time, though he had to upgrade his milk cooling system. The method boosted reproduction without hormones and ensured continuity even with staff shortages.

John decided to give flexible milking 'a crack' when he heard DairyNZ senior scientist Paul Edwards talking about it at a field day. This led him to contact Paul and he subsequently became one of the commercial farms contributing to the flexible milking research project.
Experimenting with different milking schedules during periods of summer dry led John Totty to adopt a flexible milking strategy, milking 10 times in seven days (10-in-7) full-season.
After trying OAD (once-a-day) and 3-in-2, John says 10-in-7 seems to work best for his Jersey/Jersey-cross herd and the farm’s dryland system.
It’s helping to increase profitability through improved animal health, better reproductive results, and staff retention. There are also cost savings related to less milking, all without the large drop in production that we experienced with OAD.

"One of my hopes with using flexible milking was to improve the herd’s mating performance through better energy status and management through the early lactation period."
In the first season of full-season 10-in-7 milking (2020/21), John was so confident about a positive outcome that he chose to drop all reproductive intervention, even though 15 percent of the herd had received CIDRs previously.
"Even if we held the same performance as last season (2019/20) it would still be a win if we could do it without using CIDRs," says John.
This approach paid off. Not only was performance maintained but the 6-week in-calf rate improved by 10%. Alongside this, John reduced mating length from 12 to 11 weeks without compromising his not-in-calf rate, which decreased by 2% from 13% to 11%, providing him with greater culling and selection opportunities.
"A drop of 2% was good, considering that if we’d stayed at 12 weeks, it would have been closer to a 4% gain," says John.
10-in-7 has benefited both animals and people evenly. With 10-in-7 it's always a thrill to drive out and inspect the cows. They never look skinny no matter the time of year.
John Totty
With a few of his staff moving on, John took the opportunity to use flexible milking to attract the right people to the team. Rather than ‘dairy speak’ and using language such as 'we milk full season 10-in-7' John spoke about the benefits of flexible milking. When advertising, he explained his system using terms such as '29% fewer milkings than traditional TAD and four sleep-ins per week.' This tactic worked a treat. John was able to fill all positions with good quality staff, despite the chronic staff shortages the industry is experiencing.
With a reduced milking frequency, John has found that he now has time to step back and act as an operations manager and business owner, rather than being 100% hands on all the time.
"This shift has come from a mixture of having a good team and time to spend time building the team and farm manager’s skills, as well as developing processes for them to make their own informed decisions. That allowed me to remove myself from the day-to-day operations and decision making." John says.
Early in the season, it became obvious that John was going to face some milk cooling issues on one of the farms. In the winter of 2020, he upgraded his cooling system as he had previously had problems getting milk cool enough in the required timeframe over summer.
Even with a new cooling system, it became apparent in late spring 2020/21 that it wasn’t coping, and John was aware this would only worsen as temperatures rose over summer. To fix the problem he had to upgrade his brand-new unit to the next size up, despite having been advised to the contrary the previous winter. Once the larger cooling unit was in place, there were no further hiccups.
Repro/mating performance – 10% increase in 6-week in-calf rate without hormone intervention.
Maintained per cow production while increasing cow numbers. (2019-2020 milked 930 cows at peak and 2020-2021 milked 996 at peak.) However, fell short of 400kgMS/cow target due to acidosis from fodder beet in autumn.
Able to maintain milking and farm jobs with staff shortages without staff hours going through the roof.
More freedom for John to step back and act as ops manager and business owner, rather than being hands-on all the time – mixture of having a good team around him and having the ability to spend time building manager and team skills so that he wasn’t needed for the day-to-day decisions.
Attracting the right people into positions – using their terms and language – rather than saying milking 10 times in 7 days, sold it as 29% less milkings, four sleep-ins a week etc.
As part of the DairyNZ Flexible Milking Project, we closely followed six farms using flexible milking strategies and provided 6-weekly updates for three of them throughout the 20/21 season. Others have an annual summary and commentary. Read about John’s experiences below.

John's Comments
The rainfall has been extremely kind this year, with almost weekly rains through the summer period, meaning that not only was there no need to feed out over summer – a rarity in itself, but there was also silage to harvest right the way through.
Because we haven’t had to feed out, we have had a lot more time on their hands which have allowed for
Throughout this season, we have been able to progress farm management skills of the team, who are able to manage the day to day aspects of the farm (e.g. grazing rotations, feeding decisions etc.), allowing me to step away to do strategic planning and overseeing while knowing the farms are being well looked after.
The big focus going forward now is days in milk.
The girls were re-checked on the 9th, with the final 6-week in-calf rate raising to 74% (was sitting at 72% before rechecks) with a 13% not-in-calf rate (this is a 9% increase in 6wk ICR on last year, while also dropping from 15% intervention to 0).
Lawnhayes has held production well, however Bushside has dropped more than anticipated. We are not entirely sure why – it could be due to pasture quality from previous management, as the Bushside block had a number of managers earlier in the season, and some paddocks weren’t taken to correct residuals. The new manager is working to improve this, which could have led to a slightly lower production on this block, but hopefully as the quality increases, we will continue to hold current production.
We have all of our staff sorted for next year.
Lameness has remained very low. Mastitis has increased in the Bushside shed compared with last season. We have not identified exactly why this is happening yet – it is not extremely high numbers, but still up on last year.

A typical day over calving
Over calving, John normally runs a minimum work policy – so long as the staff have milked and fed the cows, and collected and fed calves, then they can head home, rather than filling in time with extra jobs. This season, due to an extension of both yards and changes in tracks around the yard to accommodate the increase in cow numbers, the staff have been doing additional work to finish the fencing and yard work between milkings.
A typical day at the beginning of calving while milking OAD looks like:
Over time, as more cows are calved, milking time is pulled earlier and generally reaches a point where they switch to TAD so that new mums can be brought to the shed in the afternoon during daylight instead. This year, it was at this point that they have switched to a 10in7 milking interval instead.

Could reducing the number of milkings in a week help the dairy sector attract new staff and improve work-life balance? One farmer who’s gone to a flexible milking schedule is John Totty in Canterbury, currently starting his second full season milking 10 times in 7 days. What were his reasons for changing his milking schedule, and what kind of outcomes is he seeing?
