Compare that to a 520kg Friesian doing 450kg/MS, and the Jerseys are giving you a big advantage.” “Trade mark of Chartered Accountants Australia and New Zealand and used with permission”.

Back on the farm, Ashvale’s cows averaged 504kg in milk solids production last year, with several producing over 700kg. Brought up on a dairy farm near Inglewood in Taranaki, Rodney initially worked for the Post Office in Wellington but endured city life for only five years before dairying lured him back. He started working in 1968 for the Countenan Jersey Stud at Waharoa, near Matamata, before buying a couple of their cows in 1971 as the foun- dation of a contract milking herd. Three years later Rodney and wife Jocelyn bought this herd and went 50/50 sharemilking for six years. In 1980 they were fortunate enough to draw a farm in a Lands and Survey ballot for a 56ha block at Ngatea, where they farmed for the next 13 years. The couple then made the big shift to Southland in 1993 as part of the second wave of dairy-farmers converting sheep country to cows, taking up 165ha of virtually flat land. Over the next few years they were able to pur- chase more land adjacent, and in 2000 they split it into two, the home farm comprising 156ha and the second a sharemilking platform of 172ha. At the end of the 2020 season their 50/50 sharemilker of 13 years took his skills to Australia, so they sold that farm to focus entirely on the home block. Rodney and Jocelyn’s son Mark Dobson and his wife Ashley now lease the home herd and 50/50 sharemilk, while Rodney oversees the young stock on two adjacent dry-stock blocks. Rodney says he hopes his efforts have achieved something in his 50-odd years of farming his beloved Jerseys, and that he’s left a legacy for the future.

The 582-cow Jersey herd, which is part of the wider Kirkham group, outperformed both their Friesian and crossbreed counterparts across a range of key performance indicators including production per hectare, production per cow, and farm working expenses. The Jersey herd averaged 465 kgs of milksolids per cow – well over 100% of their liveweight - and 2,068 kgs of milksolids per hectare. That was 4% higher than the Friesian herd and 11% higher than the crossbreed herd on a per cow basis. On a per hectare basis the Jersey’s performance was even more impressive at 7% higher than the Friesian herd and 20% higher than the crossbred herd. The Kirkham’s farming business consists of four dairy farms milking over 2,700 cows in total, as well as a calf rearing and grazing unit. Within the wider operation are three dairy farms all located in a close radius, 10km south of Te Awamutu. “The cluster of three farms are within a stone’s throw of each other. “They are run under the same management and feed systems, with comparable contour and pasture growth which puts us in a unique position of being able to make these comparisons,” says Brad Eyre, Operations Manager. Brad, the Kirkham’s nephew, joined the busi- ness 13 years ago, starting as a Contract Milker before progressing to Operations Manager in 2016. Brad admits that when he started with the Kirkham Group, he was not in favour of maintain- ing the Jersey herd. “When I first came to the farm I wanted to cross the Jersey herd,” says Brad. However, that didn’t eventuate and now the group have a Jersey herd (Pepi Oaks), a Friesian herd (Allen Oaks) and crossbreed herd (Oakwood) as part of their home cluster at Tokanui, with a further dairy farm at Waiterimu, milking cross- breed cows. The three central farms are stocked at a similar liveweight per hectare and have the same inputs including maize, palm kernel, kiwifruit, and grass silage. While Jersey’s efficiency is well proven, it is sometimes argued that the per animal costs as- sociated with a higher stocking rate can offset the advantage. This is something that the Kirkham’s figures challenge. “Pepi Oaks has the lowest farm working expenses of all three farms in the cluster at $4.37 per kg of milksolids,” says Brad. The other two farms in the cluster have farm working expenses of $4.86 (Friesian herd) and $4.77 (crossbreed herd). So, what sets the Jersey herd apart? Jim believes that the quality of the herd has something to do with it but also puts the success of his Jerseys down to the efficiency of the breed and their suitability to their system 4 operation. “Pepi Oaks sits comfortably within the top 5% of New Zealand herds for both breeding worth and production worth and was established by my father back in 1975 so there is a lot of history behind it.” Jim’s Dad came to Te Mawhai in 1960 and originally milked shorthorns but after an out- break of TB had to cull his herd, replacing it with Jerseys. “Dad purchased a line of heifers from Hodable Farms who were the first people in New Zealand to do artificial breeding.” “It was a good line of stock and we continued the practice of artificially breeding yearlings, something we have done with all our herds.” The combination of Premier Sires and AB mating yearlings for 30 years has helped to drive genetic gain. Pepi Oaks have a breeding worth (BW) of 194 and a production worth (PW) of 220, while Allen Oaks (Friesian) has a breeding worth of 110 and production worth of 124, and Oakwood (crossbreed) a breeding worth of 127 and produc- tion worth of 140. The same approach to mating is taken with all three herds – with four weeks of AB followed by 4 weeks running bulls, and finishing with two weeks of short gestation semen. This year the farms will use sexed semen for the first two weeks of AB over the top 25% BW cows and put the bottom 20% to beef. So, are there plans to convert to all Jersey? For now, the group is happy to have a foot in each camp when it comes to their breeding. “These things tend to be cyclical, but right now we are very happy with the performance of our Jersey herd,” says Brad. “My grandad will certainly be happy I didn’t cross the Jerseys.” “Pepi Oaks sits comfortably within the top 5% of New Zealand herds for both breeding worth and production worth and was established by my father back in 1975 so there is a lot of history behind it. Dad purchased a line of heifers from Hodable Farms who were the first people in New Zealand to do artificial breeding.”
