The Claim

In newly received cattle, dietary energy density exceeding 1.10 Mcal NEg/kg DM does not consistently improve performance and is associated with an increased risk of morbidity, indicating the existence of an optimal energy range for receiving diets.

In plain English

For newly arrived cattle, feeding diets with more than 1.10 Mcal NEg/kg dry matter does not reliably improve growth or health and may increase illness rates, suggesting there is a specific energy level that works best.

See the scientific wording

Increasing dietary energy density in newly received cattle beyond 1.10 Mcal NEg/kg DM does not consistently improve performance, and may increase morbidity risk, suggesting an optimal energy range exists for receiving diets.

Why this might work

When cattle eat too much high-starch feed, bacteria in their stomach produce too much acid, which lowers the stomach's pH and damages its lining. This allows toxins from the gut to leak into the bloodstream, triggering widespread inflammation. The inflammation tricks the brain into reducing hunger and shifts the body's energy use toward fighting infection instead of growth, making the animal sick and slowing its weight gain.

    Feeding cows more energy than 1.10 Mcal per kg of dry matter doesn’t help them grow better, but it does make them sicker—like giving too much sugar to a kid. There’s a just-right amount that keeps them healthy and growing well.
