# Bird profiles (standard growth curve)

> Set the day-by-day breed standard that GrowTak compares every batch against.

<Note>
  Managing bird profiles is **admin only**. Find it under **Master → Product Profiles**.
</Note>

A **bird profile** (Product Profile) is the **breed standard** — what a healthy flock *should* achieve at each day of age. GrowTak compares every batch's live numbers against this curve in charts and reports, so you can instantly see whether a flock is ahead of or behind standard.

Your company comes with a starter profile (e.g. a Cobb profile with entries for days 1–49). You can edit it or add profiles for other breeds.

## What a profile contains

| **Name**         | e.g. *Cobb Profile*. This is what you pick when creating a batch. |
| **Product type** | The bird type the profile belongs to.                             |
| **Status**       | *Active* profiles are selectable on new batches.                  |
| **Remark**       | Optional notes.                                                   |

**Profile details** — one row per day of age:

| Column                     | Meaning                                    |
| -------------------------- | ------------------------------------------ |
| **Age**                    | Day of life (1, 2, 3, …).                  |
| **Std. Mortality %**       | Expected cumulative mortality at that age. |
| **Std. Feed per Bird (g)** | Expected feed consumed per bird.           |
| **Std. Body Weight (g)**   | Expected average live weight.              |
| **Std. FCR**               | Expected feed conversion ratio.            |
| **Remark**                 | Optional.                                  |

## Editing the curve

* Add or remove rows to match the length of your growing cycle.
* Use the **clone** and **reorder** controls on each row to build the table quickly.
* Enter realistic, breed-specific figures — every "vs standard" chart and the **FCR variance** used in advanced GC schemes depends on these numbers.

<Warning>
  A profile that's already used by a batch **cannot be deleted**. Set it to *Inactive* instead.
</Warning>

<Tip>
  Get the standard body weight and FCR right first — these are the values supervisors and reports check against most often. You can refine mortality and feed figures later.
