The gates at Bygdøy kongsgård opened at 12:30 p.m. This past Sunday, signaling one of the most anticipated transitions of the Norwegian spring. A large crowd gathered at the royal estate to witness the traditional kuslipp—the annual release of the dairy herd from their winter quarters into the fresh greenery of the summer pastures.
For the slightly more than 50 dairy cows involved, the event marks the end of a long winter confined to the barns. For the spectators, it is a celebrated ritual of the season, blending agricultural practice with a public spectacle that draws families and animal lovers to the Bygdøy peninsula in Oslo.
The release is more than a simple change of location; it is the culmination of a meticulously managed preparation process designed to ensure the health and appearance of the herd. According to the estate, the week leading up to the release is dedicated to intensive grooming, ensuring the cows are “at their most beautiful” for the public appearance.
The Science of the “Spring Glow”
While the grooming may seem cosmetic, the preparations at Bygdøy kongsgård include critical welfare measures. One of the more unusual but essential details of the process is the application of sunscreen to the cows’ udders. Because the skin on the udder is sensitive and pale, it is highly susceptible to UV radiation during the sudden increase in sunlight that accompanies the Norwegian spring.
Without this protection, the cows risk painful sunburns and inflammation, which can compromise their health and milk production. By applying a protective layer of sunscreen, the farm staff mitigate the risks of the “vårsola” (spring sun), ensuring the animals transition comfortably from the shaded environment of the barn to the exposed open fields.
“The last week before the release, the cows are clipped and groomed so that they are at their very best,” the estate noted via their official communications.
A Royal Working Landscape
Bygdøy kongsgård occupies a unique position in Oslo’s geography and the Norwegian Royal Family’s estate. Unlike purely ceremonial residences, the farm operates as a functional agricultural entity. This dual identity allows the public to engage with traditional farming practices within the heart of the capital, providing a tangible link between urban residents and the rural traditions of the country.

The kuslipp serves as a primary point of engagement for the community. By opening the event to the public, the estate fosters transparency in animal husbandry and educates visitors on the seasonal cycles of dairy farming. The movement to summer pasture is not merely traditional but is essential for the cows’ psychological and physical well-being, allowing them to graze naturally and exercise after months of confinement.
Timeline of the Release Process
The transition from the barn to the pasture follows a strict sequence to ensure order and animal safety.

| Phase | Activity | Purpose |
|---|---|---|
| Pre-Release Week | Clipping and Grooming | Aesthetic preparation and hygiene |
| Final Prep | Sunscreen Application | UV protection for sensitive udders |
| Event Day | 12:30 p.m. Gate Opening | Controlled release to summer pasture |
| Post-Release | Pasture Monitoring | Ensuring herd integration and health |
The Ecological Impact of Summer Grazing
Beyond the spectacle, the release of 50 dairy cows onto the Bygdøy pastures plays a vital role in land management. Controlled grazing is a traditional method of maintaining the cultural landscape, preventing the overgrowth of brush and maintaining the biodiversity of the grasslands.
The cows act as natural lawnmowers, managing the vegetation in a way that supports various insect species and maintains the open vistas that characterize the royal estate. This symbiotic relationship between the livestock and the land ensures that the estate remains both a productive farm and a preserved historical site.
For those looking to visit the estate or learn more about the herd’s schedule, official updates and visitor guidelines are maintained on the Bygdøy kongsgård website.
As the herd settles into their summer routine, the estate will continue to monitor the animals’ health throughout the warmer months. The next major phase for the herd will be the gradual transition back to winter housing as the temperatures drop in the autumn, completing the annual cycle of the royal farm.
