The Claim

In beef cattle, feeding a grass silage diet compared to a concentrate diet increases plasma and muscle vitamin E levels, reduces lipid oxidation in loin steaks during 4 to 7 days of retail display, and improves colour stability under modified atmosphere packaging (75% O2:25% CO2), resulting in enhanced meat shelf life and oxidative stability.

Cause and effect
1 study reviewed
In plain English

Beef cattle fed grass silage instead of concentrate feed have higher vitamin E in their blood and muscle, less fat breakdown in their meat during storage, and better meat color under oxygen-rich packaging, leading to longer shelf life and reduced oxidation.

In beef cattle, a grass silage diet compared to a concentrate diet increases plasma and muscle vitamin E levels, reduces lipid oxidation in loin steaks during 4 to 7 days of retail display, and improves colour stability under modified atmosphere packaging (75% O2:25% CO2), which enhances meat shelf life and oxidative stability.

Why this might work

When cattle eat grass silage instead of grain, they absorb more vitamin E from their food. This vitamin E builds up in their muscle tissue and stops fats from breaking down when exposed to oxygen. This keeps the meat looking red and fresh longer and prevents it from becoming rancid.

  1. Study: Effects of breed and a concentrate or grass silage diet on beef quality in cattle of 3 ages. II: Meat stability and flavour.

    Cows that eat grass silage instead of grain make meat with more vitamin E, which helps the meat stay red and fresh longer in the store without turning brown or going rancid.
