Milk Yield Calculator
Calculate total lactation milk yield and fat-corrected milk (FCM).
How to Use the Milk Yield Calculator
- Enter the average daily milk yield (liters).
- Enter the lactation length (days).
- Enter the milk fat percentage.
- Click Calculate to get total yield and FCM.
Use Cases
- •Assessing dairy cow productivity.
- •Comparing cows on a 305-day yield basis.
- •Calculating milk fat output.
- •Breeding evaluation and selection work.
Formula
Total yield = daily yield × lactation days. FCM = yield × (0.4 + 15 × fat% / 100).
Frequently Asked Questions
What is FCM?
Fat-corrected milk (FCM) is a standardized measure that adjusts milk yield to a 4% fat baseline for comparing cows.
What is the normal lactation length?
The standard lactation for dairy cows is 305 days. Enter 305 days to calculate the standard 305-day yield.
What is a normal milk fat percentage?
Most dairy breeds produce milk with 3.5-5.0% fat. Jersey cows can produce milk with up to 6% fat.
