Tillamook - Farms & Farmers


Dairy Barns Systems' business development manager, Graham Petrie and team travelled overseas to Oregon, USA to look at dairying, particularly off paddock solutions and how they are integrated into farming systems. Here's a rundown of what they got up to on the trip.

Tillamook Dairy Farms

Our first destination was Portland, the state capital of Oregon, and then a 90-minute drive west to the town of Tillamook, pop 5,136, on the south-east end of Tillamook Bay on the Pacific west coast. Tillamook is a similar size to Kerikeri and Stratford.

Our guide while visiting farms in Tillamook was Troy Downing, a dairy extension specialist from Oregon State University.

Troy told us that:

  • There are 92 dairy farms in Tillamook County, down from 160 farms 20 years ago, with an average herd size of 326 cows
  • Only one farm is on seasonal supply with the rest of 12 months supply
  • All farms have an effluent plan
  • As in New Zealand environmental issues are a concern for dairy farmers in the USA
  • Less than 20% of farms feed an all grass diet to their cows
  • Hay is currently $150-$160/ton (NZ $206-$219) and has been up to $280 (NZ $384)
  • Corn is starting to be grown and can produce up to 20 ton/acre
  • 20% of suppliers to the Tillamook County Creamery Assoc (TCCA) are less than 100,000 SCC (somatic cell count)
  • Calving is year round

One of the 92 suppliers to the TCCA we visited while based in Tillamook was Brad & Melody Cowan's Jenck Farms. They run a family based dairy business with two farms, one in Tillamook and one in neighbouring Astoria County.

The Tillamook Farm
