What typically characterizes "grass-fed" livestock?

The characteristic that best defines "grass-fed" livestock is that these animals are raised primarily on pasture, allowing them to graze on natural grasses and forage. This diet leads to different nutrient profiles in the meat, as grass-fed animals tend to have higher levels of omega-3 fatty acids and conjugated linoleic acid (CLA), compared to those raised primarily on grain. The grass-based diet is crucial because it aligns with the natural eating habits of many grazing animals, promoting better health and welfare.

In contrast, livestock that are raised primarily on grain and supplements do not meet the criteria for being grass-fed. Grain-based diets can alter the nutritional quality of the meat and may lead to health issues in the animals as they are not consuming their natural diet.

Animals raised indoors with controlled diets typically do not have access to pasture and forage. This practice often involves a more artificial feeding regimen that may rely heavily on grains and by-products rather than natural grasses.

Lastly, while specific climates can influence where grass-fed livestock are raised, the management practice itself is defined more by the feeding regimen rather than the geographical location. This means that grass-fed livestock can be raised in various climates as long as they are provided with access to pasture.
