Use real weigh dates
Count the actual days between weighings. Guessing the period can make gain look better or worse than it is.
Average Daily Gain Calculator
See whether weight gain is strong enough for the plan.
Use this sheep average daily gain calculator to estimate liveweight gain per day from two weighings. It helps compare growth, feed results and sale readiness.

This is a planning estimate. Always compare gain with feed cost, animal health, age, breed, sex and management conditions.
How to use it
Average daily gain turns two weights into a useful trend
A single weight tells you where an animal is today. Average daily gain helps explain how fast the animal is moving toward the sale or breeding target.
Compare animals fairly
Compare similar age, sex, breed and management groups. Mixed comparisons can mislead decisions.
Link gain to cost
Growth is more useful when reviewed beside feed use, health events and expected sale price.
Management signal
Slow gain is not just a number. It is a decision trigger.
Weak average daily gain can point to feed quality, intake, parasite pressure, illness, stress, genetics or poor grouping.
The calculator gives the signal. The farm record should explain what happened around it.
- Check feed changesDid the ration, feed quality or intake change during the period?
- Check health historyRepeated treatment or stress can explain lower performance.
- Check sale timingLow gain may make extra feeding days more expensive than expected.
Connected records
HerdDeck keeps weight gain connected to the animal story.
HerdDeck Shepherd connects weights, animal cards, feed stock, treatments, finance, HARSE ration planning and reports so average daily gain can be reviewed with real flock context.
