Is grass-finished beef healthier than grain-finished beef?
According to this website, the taste test of grain-fed beef
versus grass-fed beef leaned in favor of the fully foraging
"In the past we believed that beef needed at least 45 days of
grain feeding to achieve proper marbling. Most cattle are routinely
fed between 100-200 days in a dry lot environment with no access to
the natural forage diet. In 1996 we participated in a taste test at
the University of Missouri's Forage Systems Research Centre near
Linneus, Missouri. There were five selections: 1) Beef finished on
100% confinement full grain diet, 2) Beef finished on a 75% grain,
25% forage diet, 3) Beef finished on a 50% grain, 50% forage diet,
4) Beef finished on a 25% grain, 75% forage diet, and 5) Beef
finished on a 100% forage diet."
Grain-fed beef would contain less nutrients, since the grain
must be processed, therefore taking portions of the energy out of
it. However, since the cows are directly eating the grass, the
nutrients would all be preserved and given directly to the cow.
