Healthy Eggs: What We Knew in 1932

In the 1930s, scientists and food producers were creating the first plans to take poultry off family farms and raise them in confinement. To enact their plans, they needed to create “feed rations” that would keep the birds alive and productive even though they were denied their natural diet of greens, seeds, and insects. It was a time of trial and error. In a 1932 experiment conducted by the U.S. Department of Agriculture, breeding hens were taken off pasture and fed a wide variety of feed ingredients. When the birds were fed a diet that was exclusively soy or corn or wheat or cottonseed meal, the chickens didn’t lay eggs or the chicks that developed from the eggs had a high rate of mortality and disease. But when birds were fed these same inadequate diets and put back on pasture, their eggs were perfectly normal. The pasture grasses and the bugs made up for whatever was missing in each of the highly restrictive diets. 

Eggs from pastured hens are far richer in vitamin D

Eggs from hens raised outdoors on pasture have from three to six times more vitamin D than eggs from hens raised in confinement. Pastured hens are exposed to direct sunlight, which their bodies convert to vitamin D and then pass on to the eggs. Vitamin D is best known for its role in building strong bones. New research shows that it can also enhance the immune system, improve mood, reduce blood pressure, combat cancer, and reduce the risk of some autoimmune disorders. This good news about eggs comes from a study released by Mother Earth News, a magazine that plays a leading role in promoting health-enhancing, natural foods. The editors found that eating just two eggs will give you from 63-126% of the recommended daily intake of vitamin D. Note that this benefit comes only from hens that are free to graze fresh greens, eat bugs, and bask in the sun. Most of the eggs sold in the supermarket do not meet this criterion. Even though the label says that the eggs are “certified organic” or come from “uncaged” or “free-range” hens or from hens fed an “all-vegetarian” diet, this is no guarantee that the hens had access to the outdoors or pasture. Look for eggs from “pastured” hens. You are most likely to find these superior eggs at farmer’s markets or natural food stores.

Pastured Eggs Nutritionally Superior

As it turns out, all those choices of eggs at your supermarket aren't providing you much of a choice at all. Recent tests conducted by Mother Earth News magazine have shown once again that eggs from chickens that range freely on pasture provide clear nutritional benefits over eggs from confinement operations. Mother Earth News collected samples from 14 pastured flocks across the country and had them tested at an accredited laboratory. The results were compared to official US Department of Agriculture data for commercial eggs. Results showed the pastured eggs contained an amazing:

  • 1/3 less cholesterol than commercial eggs
  • 1/4 less saturated fat
  • 2/3 more vitamin A
  • 2 times more omega-3 fatty acids
  • 7 times more beta carotene

When I started this series it was to answer the questions that so many customers ask, Why are our eggs different? Because our hens are pastured. It not only makes a significant difference in nutritional value of the eggs as I have documented here, it also makes a big difference in how they look. Since our hens get fresh greens, they end up with 7 times the beta carotene as documented by Mother Earth News. You remember beta carotene, its in carrots. Its what makes carrots orange. So when you are wondering why commercial eggs yokes are pale yellow and our eggs yokes are deep yellow to orange you are actually seeing the nutritional difference. You are seeing vitamins and minerals. The most significant difference is taste, but you will have to try that for yourself. It is a wonderful thing to find out that you can eat great tasting food that is good for you, less bad fat, more good fat, more vitamins and minerals with a great flavor. Win-WIn.

A Primer about Hay

Over the past few weeks I have discussed the difficulty in getting our first cut hay in the barn and we have had a bunch of questions about hay... What are the differences of first cut and second cut hay? Why do you wrap some hay in plastic and others not? What is wet hay? So I wanted to take a minute and answer all the questions in one post.

It is all about the dirt

In my weekly newsletter I discussed the fact that I just finished some fall fertilization and a number of folks wrote and asked pasture, lawn, or garden fertility management questions. So instead of answering them all individually I have chosen to write a series of short post that describe some of the issues associated with managing soil fertility to maximize production and in our case animal health. This is the first in the soil series. I will introduce some of the variables, players and first steps associated with managing soil fertility.

Lamb vs Veal

I was asked by a customer: Is lamb raised like veal? The point they were concerned with is the in-humane nature that some veal is raised. Today I will try to address the similarities and differences between lamb and veal.
