Health Claims of Grain-fed vs Grass-fed: Ground beef from grass-fed and grain-fed cattle: Does it matter?
"So, at this point, there is no scientific evidence to support the claims that ground beef from grass-fed cattle is a healthier alternative to ground beef from conventionally raised, grain-fed cattle."
Environmental Impact: Our beef get a predominantly forage based diet (grass/hay and some silage) with a small amount of grain until they are 80-90% of their finishing weight. For the last 10-20% of growth we feed mostly grain with enough forage to keep their ruminant digestion operating normally. Finishing with grain gives the meat better marbling & flavor. It’s also friendlier to the environment using only 70% of the resources compared to purely grass fed beef. Though we don’t finish our beef on a feedlot but here at our farm, we would fit into the ‘natural beef production’ category in this article. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4494320/
