Story at a glance:

Grass-fed and grain-fed cattle follow dramatically different paths after their first 7 to 9 months. Grass-fed cattle continue grazing naturally until 20 to 28 months, while grain-fed are moved to feedlots and fattened rapidly with corn- and soy-based diets until 15 to 18 months.
Conventional feedlot operations expose cattle to numerous chemicals including antibiotics, growth hormones, pesticides in feed and routine vaccinations — with pesticide residues in animal feed allowed to be up to 100 times higher than what’s permitted in human-consumed grains.
Grain-fed beef can contain higher levels of phytoestrogens and other endocrine-disrupting compounds due to soy and grain-based feeds, while grass-fed beef naturally contains lower levels of these potentially harmful substances.
Grass-fed beef offers superior nutrition with up to twice the riboflavin, three times the thiamine, four times the vitamin E, and 1.5 to 3 times more conjugated linoleic acid compared to grain-fed beef.
Contrary to common belief, regenerative grazing practices can increase livestock carrying capacity by 50% to 70% compared to continuous grazing, while also improving soil health, biodiversity and carbon sequestration.
