Pasture-Based Farming Enhances Animal Welfare

By Jo Robinson

Many of the news clippings below explain how farm animals benefit when they are kept out of the feedlots and allowed to mature on pasture at a normal rate of growth and production. Other items show how factory farming compromises their health and well-being. As you will see, there is a dramatic difference between the two systems of production. Choosing meat, eggs, and dairy products from grass-based farms is a highly effective way to enhance animal welfare.

New term you need to know: “by-product feedstuffs”  

Fresh pasture and dried grasses are the natural diet of all ruminant animals. In factory farms, animals are switched to an unnatural diet based on corn and soy. But corn and soy are not the only ingredients in their “balanced rations.” Many large-scale dairy farmers and feedlot operators save money by feeding the cows “by-product feedstuffs” as well. In general, this means waste products from the manufacture of human food. In particular, it can mean sterilized city garbage, candy, bubble gum, floor sweepings from plants that manufacture animal food, bakery, potato wastes or a scientific blend of pasta and candy.  

Here are some of the “by-product feedstuffs commonly used in dairy cattle diets in the Upper Midwest.”*

·  Candy. Candy products are available through a number of distributors and sometimes directly from smaller plants… They are sometimes fed in their wrappers…. Candies, such as cull gummy bears, lemon drops or gum drops are high in sugar content.

·  Bakery Wastes. Stale bread and other pastry products from stores or bakeries can be fed to dairy cattle in limited amounts. These products are sometimes fed as received without drying or even removal of the wrappers.

·  Potato Waste is available in potato processing areas, and includes cull potatoes, French fries and potato chips. Cull fresh potatoes that are not frozen, rotten, or sprouted can be fed to cows either whole or chopped. Potato waste straight from a processing plant may contain varying amounts of inedible or rotten potatoes. French fries and chips contain fats or oils from frying operations.

·  Starch. Unheated starch is available from some candy manufacturers and sometimes may contain pieces of candy.

·  Pasta is available from pasta plants and some ingredient distributors as straight pasta or in blends with other ingredients, such as candy.

Healthy Eggs:  What We Knew in 1932

In the 1930s, animal scientists were trying to determine the best diet for cows, pigs, and chickens that were raised in confinement. It was a time of trial and error. 

In a 1993 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.

milk

Super Natural Milk

By Jo Robinson

-Most cartons of milk in the supermarket show a picture of cows contentedly grazing on grass. In reality, 85 to 95 percent of the cows in the United States are now being raised in confinement, not on pasture. The grass they eat comes in the form of hay, and the ground that they stand on is a blend of dirt and manure.

-The reason for confining cows in feedlots and feeding them grain rather than grass is that they produce far more milk under these unnatural conditions. If you also inject them with bi-weekly hormones, standard practice in the dairy industry, they produce even more.

Milk them three times a day instead of two and you have the tried and true formula for today’s Super Producers. On average, cows raised in confinement produce more than three times as much milk as the family cow of days gone by and 15 times the amount required to raise a healthy calf. 

-But with so much emphasis on quantity, the nutritional content of our milk has suffered. One of the biggest losses has been in its CLA content. CLA, or "conjugated linoleic acid," is a type of fat that may prove to be one of our most potent cancer fighters. Milk from a pastured cow has up to five times more CLA than milk from a grain-fed cow. To date, most of the proof of the health benefits of CLA has come from test tube or animal studies.

But a few human studies have produced encouraging results. For example, French researchers compared CLA levels in the breast tissues of 360 women. The women with the most CLA in their tissue (and thus the most CLA in their diets) had a 74 percent lower risk of breast cancer than the women with the least CLA. If an American woman were to switch from grain-fed to grass-fed dairy products, she would have CLA levels similar to the women in the study who had the lowest rate of cancer.

-Milk from pastured cows also contains an ideal ratio of essential fatty acids or EFAs. There are two families of EFAs—omega-6 and omega-3 fatty acids. Studies suggest that if your diet contains roughly equal amounts of these two fats, you will have a lower risk of cancer, cardiovascular disease, autoimmune disorders, allergies, obesity, diabetes, dementia, and various other mental disorders.

-Take a few moments to study the chart below showing EFA levels in milk from cows fed varying amounts of grass and grain.The green bars represent omega-3 fatty acids, and the yellow bars represent omega-6 fatty acids. As you can see, when a cow is raised on pasture (represented by the two bars on the far left), her milk has an ideal, one-to-one ratio of EFAs.

-Milk from pastured cows offers additional health benefits. (I'm beginning to sound like a TV infomercial: "But wait! There's more!") Besides giving you five times more CLA and an ideal balance of EFAs, grass-fed milk is higher in beta-carotene, vitamin A, and vitamin E. This vitamin bonus comes, in part, from the fact that fresh pasture has more of these nutrients than grain or hay. (When grass is dried and turned into hay, it loses a significant amount of its vitamin content.) These extra helpings of vitamins are then transferred to the cow's milk.

-There's another factor as well. As I mentioned, a cow raised on pasture produces far less milk than a cow raised in a confinement dairy on a grain-based diet. This is a bane for the farmer but a blessing for the consumer. The less milk a cow produces, the more vitamins in her milk. This is because a cow has a set amount of vitamins to transfer to her milk, and if she's bred, fed, and injected to be a Super Producer, her milk has fewer vitamins per glass. It's a watered down version of the real thing.

-Oh, I almost forgot the best part of all. Dairy products from grass-fed cows taste delicious, and they have a rich yellow color that is visible proof of their bonus supply of carotenes. Serve cheese or butter from a grass-based dairy, and everyone will notice the difference. Also, your cookies and cakes will have that rich buttery color that hasn't been seen since Great-Grandma's day. (You do bake, don't you?)

Health Benefits of Grass-Fed Products 

by Jo Robinson

Meat, eggs, and dairy products from pastured animals are ideal for your health. Compared with commercial products, they offer you more "good" fats, and fewer "bad" fats. They are richer in antioxidants; including vitamins E, beta-carotene, and vitamin C. Furthermore, they do not contain traces of added hormones, antibiotics or other drugs.

Below is a summary of these important benefits. Following the summary is a list of news bulletins that provide additional reasons for finding a local provider of grass-fed food.

Summary of Important Health Benefits of Grassfed Meats, Eggs and Dairy

Lower in Fat and Calories. There are a number of nutritional differences between the meat of pasture-raised and feedlot-raised animals. To begin with, meat from grass-fed cattle, sheep, and bison is lower in total fat. If the meat is very lean, it can have one third as much fat as a similar cut from a grain-fed animal. In fact, as you can see by the graph below, grass-fed beef can have the same amount of fat as skinless chicken breast, wild deer, or elk. Research shows that lean beef actually lowers your "bad" LDL cholesterol levels.

Because meat from grass-fed animals is lower in fat than meat from grain-fed animals, it is also lower in calories. (Fat has 9 calories per gram, compared with only 4 calories for protein and carbohydrates. The greater the fat content, the greater the number of calories.) As an example, a 6-ounce steak from a grass-finished steer can have 100 fewer calories than a 6-ounce steak from a grain-fed steer. If you eat a typical amount of beef (66.5 pounds a year), switching to lean grassfed beef will save you 17,733 calories a year—without requiring any willpower or change in your eating habits. If everything else in your diet remains constant, you'll lose about six pounds a year. If all Americans switched to grassfed meat, our national epidemic of obesity might diminish.

In the past few years, producers of grass-fed beef have been looking for ways to increase the amount of marbling in the meat so that consumers will have a more familiar product. But even these fatter cuts of grass-fed beef are lower in fat and calories than beef from grain-fed cattle.

>Extra Omega-3s. Meat from grass-fed animals has two to four times more omega-3 fatty acids than meat from grain- fed animals. Omega-3s are called "good fats" because they play a vital role in every cell and system in your body. For example, of all the fats, they are the most heart-friendly. People who have ample amounts of omega-3s in their diet are less likely to have high blood pressure or an irregular heartbeat. Remarkably, they are 50 percent less likely to suffer a heart attack. Omega-3s are essential for your brain as well. People with a diet rich in omega-3s are less likely to suffer from depression, schizophrenia, attention deficit disorder (hyperactivity), or Alzheimer's disease.

Another benefit of omega-3s is that they may reduce your risk of cancer. In animal studies, these essential fats have slowed the growth of a wide array of cancers and also kept them from spreading. Although the human research is in its infancy, researchers have shown that omega-3s can slow or even reverse the extreme weight loss that accompanies advanced cancer and also hasten recovery from surgery.

Omega-3s are most abundant in seafood and certain nuts and seeds such as flaxseeds and walnuts, but they are also found in animals raised on pasture. The reason is simple. Omega-3s are formed in the chloroplasts of green leaves and algae. Sixty percent of the fatty acids in grass are omega-3s. When cattle are taken off omega-3 rich grass and shipped to a feedlot to be fattened on omega-3 poor grain, they begin losing their store of this beneficial fat. Each day that an animal spends in the feedlot, its supply of omega-3s is diminished. The graph below illustrates this steady decline.

When chickens are housed indoors and deprived of greens, their meat and eggs also become artificially low in omega-3s. Eggs from pastured hens can contain as much as 10 times more omega-3s than eggs from factory hens.

It has been estimated that only 40 percent of Americans consume an adequate supply of omega-3 fatty acids. Twenty percent have blood levels so low that they cannot be detected. Switching to the meat, milk, and dairy products of grass-fed animals is one way to restore this vital nutrient to your diet.

>The CLA Bonus. Meat and dairy products from grass-fed ruminants are the richest known source of another type of good fat called "conjugated linoleic acid" or CLA. When ruminants are raised on fresh pasture alone, their products contain from three to five times more CLA than products from animals fed conventional diets. (A steak from the most marbled grass-fed animals will have the most CLA ,as much of the CLA is stored in fat cells.)

CLA may be one of our most potent defenses against cancer. In laboratory animals, a very small percentage of CLA—a mere 0.1 percent of total calories—greatly reduced tumor growth. There is new evidence that CLA may also reduce cancer risk in humans. In a Finnish study, women who had the highest levels of CLA in their diet, had a 60 percent lower risk of breast cancer than those with the lowest levels. Switching from grain-fed to grassfed meat and dairy products places women in this lowest risk category.13 Researcher Tilak Dhiman from Utah State University estimates that you may be able to lower your risk of cancer simply by eating the following grassfed products each day: one glass of whole milk, one ounce of cheese, and one serving of meat. You would have to eat five times that amount of grain-fed meat and dairy products to get the same level of protection.

>Vitamin E. In addition to being higher in omega-3s and CLA, meat from grassfed animals is also higher in vitamin E. The graph below shows vitamin E levels in meat from: 1) feedlot cattle, 2) feedlot cattle given high doses of synthetic vitamin E (1,000 IU per day), and 3) cattle raised on fresh pasture with no added supplements. The meat from the pastured cattle is four times higher in vitamin E than the meat from the feedlot cattle and, interestingly, almost twice as high as the meat from the feedlot cattle given vitamin E supplements. In humans, vitamin E is linked with a lower risk of heart disease and cancer. This potent antioxidant may also have anti-aging properties. Most Americans are deficient in vitamin E.
