Treating all cows equally may no longer be the most effective, or sustainable, approach to managing gastrointestinal nematodes in dairy cows. This veterinary e-Book explains why selective treatment is key to improving milk production, animal health, and farm profitability, while also mitigating resistance and minimizing environmental impact.

Written by veterinary experts Dr. Nadine Ravinet and Dr. Damien Achard, the guide turns recent large-scale trial data into actionable insights for practical on-farm decision-making.

In this e-book you will find…

  • The life cycle of gastrointestinal nematodes and their impact on dairy cows.

  • Risks of whole-herd treatment and advantages of targeted deworming.

  • Key selection criteria: calving date, production performance, and lactation stage.

  • The role of grazing intensity and Time of Effective Contact (TEC) in treatment response.

  • How to interpret bulk tank milk antibody tests more meaningfully.

  • Why injectable anthelmintics are essential for selective deworming.

  • Evidence of how optimizing treatment improves profitability and sustainability.
