The aim
To assess the economic benefits of preventive treatment for cows with negative energy balance (NEB).
Steps of the experiment
- Create test and control groups.
- Compare the difference in energy-corrected milk (ECM) production between treated and untreated cows.
- Calculate the additional profit generated by treated cows.
The research work was conducted on a selected dairy farm. Using the Brolis HerdLine application, 52 cows were identified as being in a negative energy balance state and were subsequently divided equally into test and control groups. The number of lactations and number of days in milk were also taken into account. The cows in the test group were provided with treatment and prophylaxis (monensin bolus), while those in the control group were not. Observation of these cows lasted for 122 days.
The results
- Treated cows produced 3.46 kg more milk (ECM) per day compared to untreated cows.
- The additional profit per treated cow per day, after deducting treatment costs, was €1.09.
