Average daily gain (ADG) is a measurement of the average daily body weight change of an animal over a specified period of time. Average daily gain is calculated as follows: ADG (average daily gain) = (Final weight – Initial weight) / Days on test
It can also be expressed as a ratio as follows: ADGR (average daily gain ratio) = (ADG / Breed-test group average ADG) x 100
Initial and final weight data can be obtained as combinations of weights from specific testing periods (such as from feed intake tests), or from combinations of birth, weaning, yearling, mature, or harvest weights.
