Welcome to our farm Oost-Gein!

City farm Oost-Gein is a dairy farm with dual purpose cows (suitable for fine milk and fine meat), of which the old Dutch "Groninger Blaarkop" accounts for the greatest part of the livestock. The organic city farm Hartstocht forms the basis of the company. Around this, many secondary activities have been developed, which are closely connected to our primary activity (the breeding of cows).

These secondary activities are:

Farm products

We sell organic meat of Blaarkop cows and steers, and raw milk. Every once in a while, we sell the meat of the Hungarean Mangalitza pig. We try to produce our farm products with the highest quality, by treating the animals well and cooperating with other craftsmen. You can subscribe yourself via the contact form for the "meat newsletter", so that you will receive updates about newly and freshly available cow and pig meat continuously.

The compost branch

The intake of organic materials from ecological sustained areas, such as parks in cities or protected nature areas. These organic materials will be combined with cow and horses manure, which will result in high-quality compost. We use this compost for the fertilization of our soils and we sell this compost for your garden.

We let our cattle graze on parks and other nature terrains, with which we try to attain our goal of a more balanced nature.

History of the farm Oost-Gein

Our history
The farm Oost-Gein has, just like any other farmstead, a history and a future:

1674 - The farmstead was build in 1674. During the First World War (1914-1918), the farmer's son Gijsbert den Hartog was stationed at the citadel of Nigtevecht (situated in the near neighbourhood of homestead Oost-Gein). In his spare time, Gijsbert was able to help on the farm of the three unattached brothers Schalij, who were breeding Blaarkoppen.

1936 - Gijbert buys the farmstead Oost-Gein, 28 hectares of land included. He owned 40 cows, which were to be manually milked. The milk was transported by carriage to the market of Amsterdam. After the war, machines are being used to milk the cows. At that time, milk was poured in milk cans, which were to be placed at the road. Still, a lot of the work is done manually, such ploughing.

1954 - The two sons of Gijsbert, the brothers Klaas en Rikkert (with his nickname Uncle Rijk) den Hartog were incorporated in the farm. They begin with 40 milking cows and some pigs. The company booms. The first tractors are being bought; horses get a less prominent role.

1974 - The first stable, with boxes for the cows at both sides of the structure and its threshing-floor in the middle, was build. It was one of the first, which was to be build in the Netherlands and soon afterwards, more of these stables appeared throughout the country. A few years later, the brothers built the second, new stable. The milk cans are being replaced by a milk tank. Moreover, "tower silos" (large silos in the shape of a large cylinder, used for the storage grass) were being build. Meanwhile, the number of cows increases and after some time, the brothers Klaas and Rijk milked 130 cows. Also, the bred 35 sheep, between 300 and 400 pigs and 30 sows.

1987 - The two sons of Klaas den Hartog (Henk and Kors) were incorporated in the farm of their father and their uncle. The milking quota had already been introduced in the Netherlands (it was a system designed to reduce the production of milk within Holland: for every amount of milk, allowances had to be bought, so that one could sell his milk legitimately). The intensive stock farming was in those days extended by the purchase of milking quota (allowance to produce 1 million litres milk per year), the breeding of Holstein cows (also known as "Americans") and the construction of new buildings on the farm. The "tower silos" were replaced by other silos, which were horizontally constructed.

Since 1997 - The branches of the cultivation of sheep and pigs became slowly but steadily less prominent. After the MKZ (animal epidemic disease) crisis in 2001 these branches were abandoned. Investments were made in other forms of agriculture; and in 1999 the compost branch was set in motion. The farm changes its policy to biological farming. Since August 2001, biological milk is being delivered to the factory. The company extensities.

2004 - The company of the brothers Henk and Kors den Hartog split up. Henk den Hartog continues farming at Oost-Gein and starts of with "a second beginning". Namely with a different way of utilising pastures (stripgrazen), as it is an ideal system to continue with an other race of cows, the Blaarkoppen. This means that the extensive, biological farm with the Blaarkop cow finally returns after 70 years.

Vegetable Garden


We have now our own little green paradise as well: The Gardens of HartstochtIt is possible to harvest your own organic vegetables from the gardens.  The gardeners Sam and Marieke can show you what and how certain vegetables can be harvested, and what will be the price. Carpe Diem! 

When? Tuesdays (10-13 u), Fridays (11-15 u), Saturdays (14-17 u)



16-03-2015 We have installed a Biomeiler on our farm, a concept that originates from Germany. Now we can generate energy by capturing warmth, generated by a compost process inside the Biomeiler. This will make the farm again a little bit more sustainable. Check out the video about the construction of the biomeiler:



21-06-2014 In no less than 2 weeks we will organize an open event on the farm. Come smell, taste and see what a farm can offer. In addition, there are many activities suited for kids! You are welcome between 11.00-16.30. On Saturday 21th of June the start of the summer!

22-03-2014: Since a long time finally a very early Spring Dance. Our cows will dance and mow happily coming Saturday from 11.30 onwards (right when we open the doors of the stable). Everyone is invited!

13-04-2013: Coming Saturday the doors of our stables will be opened for our cows, so that they can finally enjoy the fresh grass in open air. Finally spring...!

26-09-2011: Pigs on the farm: the beautiful Mangalitza pigs. Check on our new facebook page for the latest pictures. 



15-04-2011: At this very moment half of the roof of one of our stables is completely covered with solarpanels. This provides the farm with a lot of energy. You can benefit from this project as well, if you participate with the project boerzoektbuur (farmer searches neigbour). For more information, please contact us.  


05-04-2011: All the cows are outside again since the beginning of April! They were exhilarated and dancing all the time! If you were not able to witness this event or did not know about it, it is possible to registrate yourself for the mailing list to keep you informed when the next cow dance will happen every spring. On our farm this draws much attention of people from accross the entire country, and we would like you to be a part of this! To watch the so-called "cow dance" see: http://www.youtube.com/watch?v=kdJ0ZOfG5n8


20-02-2010: The minister of Agriculture, Gerda Verburg, visited our farm at the beginning of February 2010, because we had our 100th visit of school classes for education purposes! Together with members of her ministery, the media and the mayor of Abcoude she has witnessed this lesson. There they saw to what extent these lessons contribute to the basic knowledge of children about where their food actually comes from! 


10-01-2010 New solar cells have been installed on our farm that make our farm more self-sufficient!
