However, there are other differences in the meat. Because a grass-fed animal requires more time on feed to reach a target weight, the meat has less marbling. This means the animals are less likely to grade prime and more likely to grade select or choice. Grass-fed animals are typically leaner with lower fat and calories. Grass-fed animals are typically subject to less stress than grain finished. Animals that have been stressed release hormones into the meat which results in it being less tender. However, just because animals are grain-fed does not automatically mean they was stressed. Stress is related to lots of factors such as animal handling, management and transportation before slaughter. Lastly, studies have also shown that grass-fed meat contains more vitamins A and E, conjugated linoleic acids and omega-3 fatty acids.
- How Can Production Practices Affect the Food We Eat? A grass-fed animal has many differences from a grain-fed animal. First has to deal with marbling. It takes longer to put on weight when being grass-fed. This means there is less fat that builds up in the meat. This creates a more desirable cut of meat. This is now considered a 'healthier' cut of meat. Grass-fed cows also have been found to endure less stress. Stress can cause the animal to release hormones that can change the taste of the meat. Not all grass-fed cows endure stress, but it is definitely a possibility. Lastly, grass-fed cows contain more nutrients such as vitamins A and E, omega-3 fatty acids, etc. All these factors change the way the meat tastes and its positive effects on us after eating it, which is a driving force for the promotion of grass-fed animals.
