For the cows, living and grazing on the pasture all day and night is better than living in confinement facilities or dry lots. As a veterinarian, I would commonly recommend that sick cows be placed out into a grassy meadow to help them recover from their ills. Eating the grass is the best way to reestablish rumen health and to increase intakes when a cow gets a digestive disorder. Cows that graze on pastures are cleaner, and they develop fewer foot and lameness issues than cows that live on concrete. When cows eat grass on pasture, they are also more likely to have good reproductive health, udder health and cleaner milk.
“You are what you eat” applies to cows too… What a cow eats can have a major effect on the nutrient composition of the Milk. This is particularly evident when it comes to the fatty acid composition. Grass-fed usually contains less total fat than grain-fed Cows, which means that gram for gram, grass-fed beef contains fewer Minerals. But the composition of the fatty acids is vastly different, which is where grass-fed really shines
