What is better than pasture-raised pork? Pasture-raised pork that’s finished on acorns.

Our latest restock on pork is just that. Throughout the fall, we moved the hogs through the woods weekly to chow down on acorns. Pigs are gluttons for acorns and when they amble into a new paddock, it is comical to see 56 pigs immediately put their heads down like vacuums and scavenge for acorns across the forest floor.

The pigs know what’s good for them. Acorns are a high-energy feed, which produces pork that is high in unsaturated fat, omega 3’s and oleic acid. Oleic acid, also found in olive oil, contributes to the juiciness and tenderness of the meat. This is why the Spanish often to refer acorn-raised Iberico pork as “olive oil on four hooves”.

Raising hogs amongst nut trees has a long history. Partially because pigs’ natural habitat is a woodland setting where they have shade and plentiful food. Think of their ancestor — the wild boar — who lived in the woods long before domestication. Iberico pork is perhaps the most famous, as this prized pork is raised on the Iberian peninsula in oak savannas or “dehesas.” But this practice is common around the world.

Pigs raised in the woods create healthier meat, happier animals, and an enterprise that’s better for the farmer’s pocketbook. Since pigs are monogastric animals, like humans, they cannot digest plants like ruminant animals. To complement their foraging on pastures, we supplement them with a non-GMO feed. We are proud that we source our feed from a family farm in Fairfield County, but the cost adds up.

Lucky for us, our pasture and woodlot rotation significantly offsets our feed costs. Because of foraging, each pig consumes 100 lbs less feed throughout its life. This may not seem like a lot, but multiplied by the 90 pigs we raised this year — it’s saving us 9,000 lbs of feed per year!

So dig in to a juicy pork chop and taste for yourself the difference that acorns make.

The Nutritional Wisdom of the Body

Would you believe me if I told you I know the true expert on what you should eat? In a world full of diet fads and contradictory advice, I find it hard to listen to anyone prescribing a certain way of eating. That’s why I read Nourishment by Fred Provenza, about why livestock select certain foods in their environment. It also reveals the way all animals (including humans) feed themselves to get the specific nutrition they need as unique individuals.

The Pastured Pork Difference

I want to pull back the curtain on hog farming in the US for a moment. Most of the time, I like to keep our newsletters focused on how we farm versus putting down other practices. After all, farming is a difficult livelihood no matter the type or scale of operation. But sometimes it’s helpful to peak into the industrial food system to remember just how removed our country has become from good animal husbandry and small-scale farming.

Mid-Summer Highlights

Is it just me or is this summer flying by? I’ve been thinking about how to live in the moment amidst the busyness of the summer. We have been running and gunning — moving pigs until 10pm after a day of nonstop rain, leasing two new properties, integrating a bull with the herd for the first time, having a surprise calf, hosting on-farm events and converting a soybean field to perennial pasture. It may take me a lifetime to master the art of mindfulness, but here are some recent moments that captured my full and present attention…
