How to Use This Calculator

Enter Freedom from hunger/thirst (0-100), Freedom from discomfort (0-100), and Freedom from pain/injury (0-100).
Set Freedom to express behavior (0-100), Freedom from fear/distress (0-100), and Ambient temperature (°C).
Adjust Relative humidity (%), Body Condition Score (1-9) as needed.
Review the Overall welfare score result.
Use Temperature-Humidity Index and Heat stress level (0-4) to inform your decision.

90	80

What each input means

Freedom from hunger/thirst (0-100): Score for adequate feed and water access (100 = excellent).
Freedom from discomfort (0-100): Score for shelter, bedding, space, and environment (100 = excellent).
Freedom from pain/injury (0-100): Score for health management, injury prevention (100 = excellent).
Freedom to express behavior (0-100): Score for space, social grouping, enrichment (100 = excellent).
Freedom from fear/distress (0-100): Score for low-stress handling, calm environment (100 = excellent).
Ambient temperature (°C): Current or average ambient temperature in Celsius.
Relative humidity (%): Current or average relative humidity.
Body Condition Score (1-9): Average BCS of the herd (beef cattle: 1=emaciated, 9=obese, ideal 5-7).
Lameness prevalence (%): Percentage of herd showing lameness.

What each result means

Overall welfare score: Weighted average of Five Freedoms scores (0-100).
Temperature-Humidity Index: THI value — above 72 indicates heat stress for cattle.
Heat stress level (0-4): 0=None, 1=Mild, 2=Moderate, 3=Severe, 4=Emergency.
Body Condition Score: Average BCS of the herd.
Hunger/thirst score: Freedom from hunger and thirst assessment.
Comfort score: Freedom from discomfort assessment.
Pain/injury score: Freedom from pain and injury assessment.
Behavior score: Freedom to express normal behavior assessment.
Fear/distress score: Freedom from fear and distress assessment.

How this is calculated

Worked example, using the default values

Identify Input Parameters
4 parameters
Freedom from hunger/thirst (0-100) = 85, Freedom from discomfort (0-100) = 75, Freedom from pain/injury (0-100) = 80, Freedom to express behavior (0-100) = 70 = 9 input(s) provided
Calculate Overall welfare score
Overall welfare score = hungerThirst * 0.25 +
78.8 = 78.8
Calculate Temperature-Humidity Index
Temperature-Humidity Index = tempF - (0.55 - 0.0055 * relativeHumidityPct) * (tempF - 58)
77.7 = 77.7
Calculate Heat stress level
2 = 2
