What do you mean by day gain?

To calculate daily gain (often referred to as Average Daily Gain, or ADG) in livestock, including poultry, you can follow this formula:
Formula:
<math xmlns=”http://www.w3.org/1998/Math/MathML” display=”block”><semantics><mrow><mtext>ADG</mtext><mo>=</mo><mfrac><mrow><mtext>Final Weight</mtext><mo>−</mo><mtext>Initial Weight</mtext></mrow><mtext>Number of Days</mtext></mfrac></mrow><annotation encoding=”application/x-tex”>\text{ADG} = \frac{\text{Final Weight} – \text{Initial Weight}}{\text{Number of Days}} </annotation></semantics></math>ADG=Number of DaysFinal Weight−Initial Weight
Steps:
-
Measure Initial Weight: Record the weight of the animal at the start of the measurement period.
-
Measure Final Weight: Record the weight of the animal at the end of the measurement period.
-
Count the Days: Determine the total number of days you measured the weight.
-
Apply the Formula: Subtract the initial weight from the final weight, then divide by the number of days.
Example:
- Initial Weight: 1,500 grams
- Final Weight: 2,000 grams
- Number of Days: 10
Calculation:
<math xmlns=”http://www.w3.org/1998/Math/MathML” display=”block”><semantics><mrow><mtext>ADG</mtext><mo>=</mo><mfrac><mrow><mn>2000</mn><mo>−</mo><mn>1500</mn></mrow><mn>10</mn></mfrac><mo>=</mo><mfrac><mn>500</mn><mn>10</mn></mfrac><mo>=</mo><mn>50</mn><mtext> grams/day</mtext></mrow><annotation encoding=”application/x-tex”>\text{ADG} = \frac{2000 – 1500}{10} = \frac{500}{10} = 50 \text{ grams/day} </annotation></semantics></math>ADG=102000−1500=10500=50 grams/day
This means the daily gain is 50 grams per day.

To calculate a daily gain, subtract the initial value (e.g., opening price or cost) from the final value (e.g., closing price or sale price), then divide the difference by the initial value and multiply by 100 to get the percentage gain.

To get daily gain you need to know the initial weight of the bird (or average weight if they are a group of birds) in a particular period DIVIDED by the number of days in that particular period [(final weight – initial weight)/number of days]. Weight gain is obtained by: final weight – initial weight.

Average Daily Gain (ADG)
ADG: Final weight – Initial weight/Number of days
Here,
Final weight: 120 gm
Initial weight: 20 gm
Number of days: 10
So, ADG:120-20/10
=10 gm/day

Day gain (or average daily gain, ADG) is a measure of how much weight an animal gains per day over a specific period. It is commonly used in livestock and aquaculture to track growth performance.
Formula for Day Gain (ADG):
ADG = \frac{\text{Final Weight} – \text{Initial Weight}}{\text{Number of Days}}
Example Calculation:
If a fish weighs 50g at the start and 200g after 30 days, the ADG is:
ADG = \frac{200g – 50g}{30} = \frac{150g}{30} = 5g/day
