# Batch programs (feed & vaccine schedule)

> Build a reusable day-wise feed and medicine schedule for your flocks.

<Note>
  Managing batch programs is **admin only**. Find it under **Master → Batch Programs**.
</Note>

A **batch program** is a reusable plan of **which feed and medicine to give on which day** of the flock's life. Once a batch is linked to a program, GrowTak uses it to:

* **Project feed demand** ahead of time (so you can order feed before it runs out).
* **Auto-detect the feed type** when a supervisor records a [day entry](/daily-entry/recording-a-day-entry).
* Drive the **vaccine due** alerts and report.

Your company starts with a *Default Program*; edit it or create your own.

## Building a program

Open a program (or select **New batch program**).

Top fields:

| Field      | Notes                                           |
| ---------- | ----------------------------------------------- |
| **Name**   | e.g. *Standard 42-day Broiler*.                 |
| **Status** | *Active* programs can be chosen on new batches. |
| **Remark** | Optional notes.                                 |

**Program details** — one row per scheduled item:

| Column                | Meaning                                                                                 |
| --------------------- | --------------------------------------------------------------------------------------- |
| **Product**           | The feed grade or medicine/vaccine.                                                     |
| **Quantity per Bird** | For **feed**, the total quantity per bird in **grams**. For **medicines**, enter **0**. |
| **Days**              | The day of life this item starts/applies.                                               |
| **Remark**            | Optional.                                                                               |

<Info>
  The on-screen hint says it clearly: *"For Feed enter total quantity in grams. For medicines enter zero."* Feed rows drive feed projection; medicine/vaccine rows drive the vaccination schedule and alerts.

Use the **clone** and **reorder** controls to assemble the schedule quickly, then save.

## How the program is used on a batch

When you create a batch you pick one program. After that:

* The batch's **Projection** tab forecasts feed demand using the program plus the batch's *feed lead time* and *safety stock* days.
* On each day entry, the **Feed Type** is pre-selected based on the program and the batch's current age — the supervisor only changes it if a different feed was actually used.
* The batch's **Daily Schedule** tab shows the program laid out against the flock's calendar.

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