Since 2007, Deck Family Farm has been caring for the Jersey cows owned by Creamy Cow Cooperative Herdshare Owners. After reading the material below, call the Deck Family Farm Office (541.998.4697) to find a Creamy Cow drop site near you, sign up and figure out which size and type of share is best for you.

Why a cooperative dairy herd?

You own the cow, we do all the work to bring you fresh creamy, and delicious raw milk straight from your herd to your home. We’ve found that this is a good way to help us all share in the responsibility of our food.

Here’s how it works:  Owner members buy a $40 share in the herd of cows and then pay a seasonal subscription to receive the milk, cream, butter, cheese and/or yogurt from your cow on a weekly basis at one of our drop-sites in Eugene, Corvallis, or Portland. This seasonal payment covers the cost of grazing, caring for and milking your cow.

Spring: March – May
Summer: June – Aug
Fall: Sep – Nov
Winter: Dec – Feb

Dairy Testing Results

A2 Beta-Casein Genotyping

In recent years the general public has been increasingly interested in dairy cow genetics due to A1 and A2 beta-casein in milk. Beta-casein is a protein that constitutes about 30% of the protein content in milk and there are 2 different forms of this protein: A1 and A2. Cows have produced A2 beta-casein since before they were first domesticated and it is considered to have health benefits. A1 beta-casein arose from a natural mutation during breed selection in European dairy breeds (generally larger, black and white breeds) and is considered less healthy. Cows have 2 copies of the gene that codes for beta-casein and can therefore posses A1/A1, A1/A2, or A2/A2 genetics. As neither the A1 or A2 trait appears to be dominant,  cows possessing A1/A2 will probably produce milk with about 50% of each type of beta-casein.

We have recently begun testing some of the cows in our dairy, as Jersey cows tend to have more A2 genetics. Testing can be fairly expensive, so we plan to gradually test the whole herd over time. Here are the results so far:

Milk Testing Results

At DFF we use an independent milk testing laboratory, Udder Health Systems in Bellingham, Washington, to test our milk for bacteria and pathogens in order to ensure that it is as high quality as possible. We send milk samples from our bulk tank to their laboratory routinely for two tests. A Standard Plate Count provides an idea of quantity of microorganisms in the milk that could have come from anywhere along the path from the udder to the bulk tank. The Total Coliform test indicates milk quality and safety from contamination, especially fecal contamination. Presence of coliforms also indicates conditions favorable for pathogenic bacteria to grow.

Both of these tests are measured in cfu/mL (colony forming units) and recommended levels based on ORMPA standards for high quality raw milk are SPC: <15,000 cfu/mL, and for the Total Coliform: <10 cfu/mL. Udder Health Systems recommends SPC: <5,000 cfu/mL and for the Total Coliform: <10 cfu/mL to be considered high quality milk.
*A level with the letter E before the value means an estimate was performed.
