Dairy cows: Controlling heifer mastitis 

Heifer mastitis has a significant impact on long-term udder health and milk yield. Find out more about the disease and how it impacts your herd and costs. 

Understanding why and how to control mastitis infections in heifers

Udder infections can be picked up from the environment or transmitted from one heifer or cow to another. Heifer mastitis before or after calving, or during the first lactation, significantly affects udder health and lifetime milk yield. There’s also an associated culling risk  particularly in cases involving major pathogens. 

This impact on your profitability, as well as on the welfare of your animals, means that it’s critical to prevent and manage mastitis in your herd. In these pages, we explain how mastitis affects your costs, look at the bacteria involved in different types of mastitis, and take you through strategies for managing, treating and preventing mastitis infections in your heifers. 

For more information, find out about our QuarterPro programme, visit the Dairy Mastitis Control Plan and use our Mastitis Pattern Analysis Tool (MPAT) for a simple, automated way of understanding transmission patterns and heifer management issues in your herd. 

Evaluating heifer mastitis and its costs

Mastitis treatment and control is one of the largest costs to the UK dairy industry, and it’s also a significant factor in heifer welfare. Read our advice on understanding the impact of mastitis on your heifer herd and profitability.
