DairyEffect | Higher Milk Yield and Milk Fat

The operation

• 315 Holstein cows in lactation
• Average herd production: 14,222 liters
• Milk fat: 4.19%
• Protein: 3.6%

Our solution

• Maize-heavy ration, with maize silage accounting for 62.5% of the forage dry matter
• Total mixed ration (TMR), formulated for 40 kg of milk
• 170 g of DairyEffect per animal per day

The goal

Increase milk fat content and milk yield.

The success

Since DairyEffect was introduced in November 2025, energy-corrected milk yield has increased markedly: from 41.91 kg in November to 42.95 kg in February and 42.86 kg in March—even as the herd’s average days in milk increased.

According to milk recording data, milk fat content has risen by 0.22 percentage points since DairyEffect was introduced. Milk quality data confirm this positive trend: fat content has remained consistently above 4%.
