The formula to calculate the Average Daily Gain (ADG) is:
\[ \text{ADG} = \frac{\text{Final Weight} - \text{Initial Weight}}{\text{Number of Days}} \]
Where:
Average Daily Gain (ADG) is a measure of the average daily body weight change of an animal over a specified period of time[^1^][^2^].
Consider an example where the initial weight is 50 kg, the final weight is 100 kg, and the number of days is 30:
Using the formula to calculate the Average Daily Gain:
\[ \text{ADG} = \frac{100 - 50}{30} = \frac{50}{30} = 1.67 \text{ kg/day} \]
This means that the average daily gain for this example is 1.67 kg/day.
