Taking the projection at 61 days as an example, we will have:

__✅ For projected weight based on average entry weight__

- Projected weight based on
__AVERAGE ENTRY WEIGHT__and average entry age is__LESS__than the projected weight age.

Average Weight Entry+ Gain Projected Weight (61 days)

__✅ For projected weight based on average exit weight__

*If there are no recorded exits, we cannot project the weight, so the projected weight is zero.*

- Projected weight based on
__AVERAGE EXIT WEIGHT__and the average exit age is__HIGHER__than the age for weight projection.

Average Exit Weight - Gain Projected Weight (61 days)

__Example: if I want to project the weight at 61 days and the average exit age is 70.6:__

Assuming Average Exit Age > Projection Age, then I sum the ADG of the daily growth chart from day 62 to day 71 (only 60% of the value). The result is projected weight gain.

- Projected Weight Based on
__Average Exit Weight__and Average Exit Age is__LESS__than Age for Projected Weight.

Average Exit Weight + Gain Projected Weight (61 days)

__Example: if I want to project the weight at 61 days and the average age at exit is 57.45:__

Assuming Average Exit Age < Projection Age, then sum the ADG from the daily growth table from day 58 (only 55% of the value) up to 61 days. The result is the projected weight gain.

If there were records of exits in the analyzed period and The average age of departure __EQUALS __the age for weight projection.

Projected weight equals ExitAverageWeight

Where:

AverageWeightEntry: It is the average weight of animals entering the phase or batch.

AverageExitWeight: It is the average output weight of the animals in the phase or batch.

ProjectedWeightGain: It is the projected weight gain based on the growth table defined for the farm.

(61 days): It is the value of days that I am using as a reference for the calculation. Here it can be 60 days, 58 days, 65 days, etc.
