Why Body Condition Scoring matters

Carrying out Body Condition Scoring sooner rather than later helps farmers identify cows that are under or overweight and take action before this affects performance or health.

The goal is to maintain condition while supporting production. When grazing conditions are poor or feed quality drops, cows can lose condition quickly, making regular monitoring especially important.

What is a Body Condition Score?

The Body Condition Score (BCS) of a dairy cow is an assessment of her fat reserves, used to evaluate energy balance. It is scored on a scale of 1 (very thin) to 5 (very fat), in increments of 0.25.

Ideal BCS targets include:

• Drying off / calving: 3.0–3.25
• Peak lactation: 2.25–2.75

As a general rule, no cow should change condition score by more than 0.5–0.75 over a lactation period.

Why BCS data is valuable

Conducting BCS across the herd enables farmers to make important management decisions, especially for cows that fall outside the desired range. Cows with a score below 2.0 or above 4.0 may need immediate attention or a more carefully managed feeding plan.

Collecting and monitoring BCS data over time can help identify herd-level issues and support timely interventions. Recording this information digitally can also make the process faster and easier to manage.

Act early to avoid problems later

Managing BCS works best when changes are made gradually. Restricting an over-conditioned cow close to calving can increase the risk of metabolic problems, so early planning is essential.

By body condition scoring regularly, you can identify cows that may need increased supplementary feed or reduced intake, depending on their condition and stage of production.

Steps you can take to correct BCS issues

• Assess the quality and quantity of feed available
• Identify calving dates and current BCS for every cow
• Group cows according to BCS where practical
• Flag thinner cows for earlier dry-off if needed
• Consider once-a-day milking before early dry-off where appropriate
• Avoid giving well-conditioned cows unnecessary extra dry-off time

Taking action early helps avoid sudden nutritional changes and supports more consistent herd performance.

How Herdwatch can help

Herdwatch makes it easy to record and track the Body Condition Score of your cows, giving you valuable insight into herd health and helping you make better management decisions.

How to add a BCS in Herdwatch

• On the home screen, select the orange plus button
• Select Body Condition Score
• Select the date and score
• Select Next
• Select the animals you want to add this BCS to
• Select Save

Set dry-off alerts

You can set Watchboard Alerts in the app to help ensure cows are dried off at the right time. Standard dry-off alerts are set for 60 days before calving for cows and 80 days before calving for heifers, but these can be adjusted in your Watchboard settings.

Generate reports

Herdwatch also lets you generate reports showing all BCS data recorded within a selected date range, making it easier to review trends and support decision-making.

Support healthier cows with better records

Body Condition Scoring is a simple but powerful tool for improving herd management. By monitoring condition regularly and recording it accurately, farmers can make better feeding, production, and dry-off decisions that support cow health and long-term performance.
