Check feed changes
Did the ration, pasture or feed amount change during the period?
Average Daily Gain Calculator
Average daily gain turns two weights into a useful trend.
Calculate total gain, average daily gain and weekly gain from two weight records. Use it to review growth, feed response and sale readiness.
Calculate ADG
Enter starting and ending weights with the number of days between measurements.
Total gain-
Average daily gain-
Weekly gain-
Growth direction-
ADG is most useful when you connect it to the reason behind the change.
Growth trend should be reviewed together with feed, health, age, group, weather and management changes.
Check health history
Illness, parasites, treatments or stress can explain slow or negative gain.
Record the next weight
A single ADG result is useful, but repeated records make the animal trend clearer.
Measurement note
Average daily gain needs two valid weights and a positive number of days between them. Very short intervals can exaggerate normal weighing variation.
