Taranaki dairy farmer Cliff Shearer's practices may seem old-fashioned, but they've helped him make his way into the history books.

When Cliff Shearer is not on his milking stool, you might find him poring over antique books for tips on how people farmed more than 200 years ago.

The hobbies and practices of this South Taranaki dairy farmer may seem old-fashioned, but they have helped him lay claim to the highest-producing Jersey herd in New Zealand.

"That's what I get up for, to break records if you like."

Meet Cliff Shearer's Jersey herd

He has thousands of antiquarian farming books, alongside his collection of Jersey cow production registers dating back to 1902.

Shearer showed Country Life his "pride and joy" - a book, dating from 1798, written by the first minister of agriculture in England. He in turn was a student of Robert Bakewell, "the greatest cattle breeder in history (who) founded the modern system of animal breeding".

Shearer says the books and records reaffirm what he has found in more than 40 years of milking Jersey cows, such as always breeding the best cow to the best bull and spreading dolomite on the pasture to prevent mastitis.

Just beyond a rose-covered fence from the house is another pride and joy, his 30-cow Jersey herd.

It may be small but it is mighty in terms of production, nearly double the New Zealand average.

"I've got the highest-producing Jersey herd in New Zealand history.

"My cows average 701kg of milk solids, and they've done over 650 kg/ms for the last 14 years."

In the 2022-23 season, 59 percent of New Zealand herds recorded milksolids production of between 300 and 450 kg per cow.

The cows are fed on just over 11 hectares of pasture and each gets a 16kg top-up of extra feed every day, a muesli including soya hull, palm kernel and molasses.

Shearer points out his highest-performing cow, standing in the shade of some tall trees.

Her claim to fame: "1062 kilos of milksolids, over 10,000 litres in 300 days."

All of his cows can be traced to one mammoth milker, Lamorna Rovers Brenda, which he bought in 1980, a year after he started farming.

While most New Zealand cows are milked in herringbone or rotary sheds, Shearer's cows stroll over to an eight-bail walk-through. He says it is one of the last remaining walk-through milking sheds in the county.

He sits on a milking stool to put the cups on, milking twice a day, single-handedly.

He hasn't missed a day's milking in 14 years, even working with six broken ribs at one stage.

That is "some 10,250 consecutive milkings", he says…
