FS25_AdjustAnimalFood

Why shouldn't chickens eat oats if you want them to? Or make grass more effective for cows? This mod gives you control over food effectiveness, crop assignments, mixed feed recipes, TMR compositions, serial/parallel consumption, and food consumption speed.

Adjust Animal Food allows you to customize the animal feeding system in Farming Simulator 2025 through an XML configuration file. Control food group effectiveness (productionWeight), consumption preferences (eatWeight), feeding mode (consumptionType), and consumption speed with a configurable multiplier (0.01x to 100x) - all without modifying map files.

Supports multiplayer.

Notes

XML Editing Required: There is no in-game UI. Configuration is done by editing an XML file that's automatically generated in your savegame folder. If you're not comfortable editing XML files, this mod may not be for you.

You can:

Add custom food groups to animals and custom ingredients to mixtures/recipes
Disable unwanted food groups or ingredients (except Grass)
Adjust food effectiveness and feeding behavior (productionWeight, eatWeight, consumptionType)
Change which crops belong to each food group (fillTypes)
Modify mixed feed recipes and ingredient proportions
Customize TMR/forage recipe compositions and ranges
Control serial/parallel consumption and consumption speed (0.01x to 100x)

You cannot:

Add or delete animal types (only modify existing: COW, PIG, CHICKEN, SHEEP, HORSE)
Add or delete mixtures/recipes (only modify existing: PIGFOOD, FORAGE)
Disable the Grass food group (causes game hang - you can change its weights)

Installation

Download the latest release zip file
Move or copy the zip file into your Farming Simulator 2025 mods folder, typically located at:
- Windows: Documents/My Games/FarmingSimulator2025/mods
- macOS: ~/Library/Application Support/FarmingSimulator2025/mods
Make sure you don't have any older versions of the mod installed in the mods folder

Usage

The mod works through XML configuration files that are automatically created for each savegame:

First Time Setup

Start your game with the mod installed and load your savegame
Save and exit the game - the mod will create aaf_AnimalFood.xml in your savegame folder
Locate the XML file in your savegame directory:
- Windows: Documents/My Games/FarmingSimulator2025/savegameX/aaf_AnimalFood.xml
- macOS: ~/Library/Application Support/FarmingSimulator2025/savegameX/aaf_AnimalFood.xml
Edit the XML with any text editor to customize your animal food system
Load your savegame - changes take effect immediately

Making Changes

The XML file contains all current game defaults when first created
The file includes documentation and examples showing how to use features like disabling items
Edit any values you want to change (see Configuration Reference below)
Values you don't change remain at game defaults
Changes are applied every time you load the savegame
The file is automatically updated if new content is added (mods, game updates)

Important Notes

5-Entry Limit: Keep total active (non-disabled) food groups/ingredients to 5 or fewer per animal/mixture/recipe. The game may not display or handle more than 5 correctly. If you want to add custom entries, consider disabling existing ones first.
CRITICAL - Never Disable Grass: Do NOT disable the Grass food group for any animal. The game's Meadow system has an internal dependency on Grass configuration and disabling it will cause the game to hang. Other food groups may have similar hidden dependencies - disable with caution.
Language-Specific: The generated XML uses your game's language (e.g., "Hay" in English, "Heu" in German)
Backup First: Always back up your XML before making major changes
Order Matters: Keep the order of food groups and ingredients in the order they should appear in the UI display
Invalid Values: Unknown crop names or invalid values will be logged but won't crash the game

Configuration Reference

The XML file has three main sections: animals, mixtures, and recipes.

Animals Section

Controls food group effectiveness and crop assignments for each animal type.

<animal animalType="COW" consumptionType="SERIAL">
    <foodGroup
        title="Hay"
        productionWeight="0.80"
        eatWeight="1.00"
        fillTypes="DRYGRASS_WINDROW"/>
</animal>

What You Can Change:

productionWeight: Food effectiveness (0.0-1.0) - higher means better productivity
eatWeight: Consumption preference (0.0-1.0) - affects PARALLEL consumption animals only
fillTypes: Space-separated crop names that belong to this food group. Most animal pens will only accept bulk or bale fillTypes and not pallets. (If you want your animals to eat cake the pen must have a pallet trigger. Not tested.)
consumptionType: Set to "SERIAL" (eat one food at a time) or "PARALLEL" (eat all foods simultaneously) - changes how animals consume multiple food types
disabled: Set to "true" to remove this food group from the game (animals won't accept this food type)

What You Cannot Change:

animalType: Used for matching only - can't add new animal types
title: Used for matching only - must match game's food group name

Mixtures Section

Controls mixed feed recipes and ingredient proportions.

<mixture fillType="PIGFOOD" animalType="PIG">
    <ingredient weight="0.50" fillTypes="MAIZE TRITICALE"/>
    <ingredient weight="0.25" fillTypes="WHEAT BARLEY"/>
    <ingredient weight="0.20" fillTypes="SOYBEAN CANOLA"/>
    <ingredient weight="0.05" fillTypes="POTATO SUGARBEET_CUT"/>
</mixture>

What You Can Change:

weight: Ingredient proportion (any positive number - automatically normalized to 1.0)
fillTypes: Space-separated crop names for this ingredient slot
disabled (on ingredient): Set to "true" to remove this ingredient from the mixture

Notes:

Weights are automatically normalized (if you use 50, 25, 20, 5 they become 0.5, 0.25, 0.2, 0.05)
When you disable an ingredient, remaining ingredients are automatically renormalized
Ingredient order must match the game's order (usually matches the order in the XML)
You cannot disable entire mixtures, only individual ingredients

Recipes Section

Controls TMR/Forage recipes for mixing wagons.

<recipe fillType="FORAGE">
    <ingredient
        name="silage"
        title="Silage"
        minPercentage="0"
        maxPercentage="75"
        fillTypes="SILAGE ALFALFA_FERMENTED"/>
    <ingredient
        name="straw"
        title="Straw"
        minPercentage="10"
        maxPercentage="30"
        fillTypes="STRAW"/>
</recipe>

What You Can Change:

minPercentage: Minimum percentage (0-100) for this ingredient
maxPercentage: Maximum percentage (0-100) for this ingredient
fillTypes: Space-separated crop names for this ingredient
disabled (on ingredient): Set to "true" to remove this ingredient from the recipe

What You Cannot Change:

name: Internal identifier - must match game
title: Display name - modification has no effect

Notes:

Percentages define the valid range for the mixing wagon UI
Ratios are automatically normalized based on your min/max ranges
When you disable an ingredient, it's completely removed from the TMR mixer UI
You cannot disable entire recipes, only individual ingredients

Consumption Multiplier Section

Control how fast animals consume their food supply. This feature is disabled by default (opt-in).

<consumptionMultiplier>
    <global multiplier="1.0" disabled="true"/>
</consumptionMultiplier>

What You Can Change:

multiplier: Food consumption speed (0.01-100)
- 0.5 = Animals eat half as fast (food lasts longer)
- 1.0 = Normal speed (default)
- 2.0 = Animals eat twice as fast (food depletes faster)
disabled: Set to "false" to enable this feature

Notes:

This feature only affects consumption rate, not food effectiveness (use productionWeight for that)
Automatically disabled if incompatible mods are detected (e.g., FS25_RealisticLivestock)
Server-authoritative in multiplayer: multiplier is applied on server, clients see the results

Practical Examples

Simple: Adjust Food Effectiveness (Weights)

The most common use case is adjusting how effective different foods are. Values range from 0.0 to 1.0.

Make hay more effective for cows (increase from 0.8 to 1.0):

<foodGroup title="Hay" productionWeight="1.0" eatWeight="1.00" fillTypes="DRYGRASS_WINDROW"/>

Make straw less effective (decrease from 0.2 to 0.1):

<foodGroup title="Straw" productionWeight="0.1" eatWeight="1.00" fillTypes="STRAW"/>

Values between 0.0 and 1.0 where higher = more effective for animal productivity.

Add Oat to Chicken Feed

Find the grain food group for chickens and add OAT to fillTypes:

<foodGroup title="Grain" productionWeight="1.00" eatWeight="1.00" fillTypes="WHEAT BARLEY SORGHUM OAT"/>

Chickens can now eat oat along with other grains.

Adjust Pig Feed Recipe

Modify the PIGFOOD mixture to use more grain:

<mixture fillType="PIGFOOD" animalType="PIG">
    <ingredient weight="0.60" fillTypes="MAIZE TRITICALE"/>  <!-- More grain -->
    <ingredient weight="0.30" fillTypes="SOYBEAN CANOLA"/>   <!-- More protein -->
    <ingredient weight="0.10" fillTypes="POTATO"/>           <!-- Less roots -->
</mixture>

The weights will be automatically normalized to 100%.

Allow More Silage in TMR

Adjust the FORAGE recipe to allow up to 80% silage:

<ingredient name="silage" title="Silage" minPercentage="0" maxPercentage="80" fillTypes="SILAGE"/>

Your TMR mixer will now accept up to 80% silage instead of the default 75%.

Add Alfalfa Silage as Alternative

If there are custom filltypes from maps and mods they can be added. ALFALFA_FERMENTED to the silage ingredient if the map has alfalfa silage:

<ingredient name="silage" title="Silage" minPercentage="0" maxPercentage="75" fillTypes="SILAGE ALFALFA_FERMENTED"/>

You can now use either grass silage or alfalfa silage in your TMR.

Disable Hay for Cows

Don't want cows to eat hay? Add disabled="true" to the hay food group:

<foodGroup title="Hay" productionWeight="0.80" eatWeight="1.00" fillTypes="DRYGRASS_WINDROW" disabled="true"/>

Cows will no longer accept hay. The food group is completely removed from the game but stays in your XML file.

Remove Grain from Pig Feed

Want to exclude wheat and barley from your pig feed mix? Disable the grain ingredient:

<mixture fillType="PIGFOOD" animalType="PIG">
    <ingredient weight="0.50" fillTypes="MAIZE TRITICALE"/>
    <ingredient weight="0.25" fillTypes="WHEAT BARLEY" disabled="true"/>  <!-- Grain excluded -->
    <ingredient weight="0.20" fillTypes="SOYBEAN CANOLA"/>
    <ingredient weight="0.05" fillTypes="POTATO SUGARBEET_CUT"/>
</mixture>

The remaining ingredients automatically adjust: Base 66.6%, Protein 26.6%, Roots 6.6%.

Exclude Straw from TMR Recipe

Don't want straw in your TMR? Disable the straw ingredient:

<recipe fillType="FORAGE">
    <ingredient name="silage" title="Silage" minPercentage="0" maxPercentage="75" fillTypes="SILAGE"/>
    <ingredient name="straw" title="Straw" minPercentage="10" maxPercentage="30" fillTypes="STRAW" disabled="true"/>
    <ingredient name="dryGrass" title="Hay" minPercentage="20" maxPercentage="50" fillTypes="DRYGRASS_WINDROW"/>
    <ingredient name="mineralFeed" title="Mineral Feed" minPercentage="0" maxPercentage="10" fillTypes="MINERAL_FEED"/>
</recipe>

Your TMR mixer will only show 3 ingredient slots instead of 4.

Change Cow Feeding from Sequential to Simultaneous

By default, cows eat foods one at a time in priority order (SERIAL mode). Change to PARALLEL mode to simulate a realistic mixed ration where cows consume multiple food types simultaneously:

<animal animalType="COW" consumptionType="PARALLEL">
    <foodGroup title="Hay" productionWeight="0.8" eatWeight="0.3" fillTypes="DRYGRASS_WINDROW"/>
    <foodGroup title="Silage" productionWeight="1.0" eatWeight="0.5" fillTypes="SILAGE"/>
    <foodGroup title="Grass" productionWeight="0.7" eatWeight="0.2" fillTypes="GRASS_WINDROW"/>
</animal>

In PARALLEL mode, eatWeight controls consumption proportions (50% silage, 30% hay, 20% grass based on the weights above). In the default SERIAL mode, cows would eat one food type completely before moving to the next.

Change Pig Feeding from Simultaneous to Sequential

By default, pigs eat all foods simultaneously (PARALLEL mode). Change to SERIAL mode to force pigs to eat one food type at a time in priority order:

<animal animalType="PIG" consumptionType="SERIAL">
    <foodGroup title="Mixed Feed" productionWeight="1.0" eatWeight="1.0" fillTypes="PIGFOOD"/>
    <foodGroup title="Grain" productionWeight="0.8" eatWeight="1.0" fillTypes="WHEAT BARLEY"/>
    <foodGroup title="Roots" productionWeight="0.6" eatWeight="1.0" fillTypes="POTATO SUGARBEET"/>
</animal>

In SERIAL mode, pigs eat Mixed Feed first, then Grain when depleted, then Roots. The eatWeight values are ignored in SERIAL mode - only productionWeight affects productivity.

Advanced: Add Custom Food Type (Staying Within 5-Entry Limit)

Want to add a custom food group? Remember the 5-entry limit! COW has 4 vanilla food groups, so you can safely add 1 custom food OR disable one vanilla and add a custom replacement.

Option 1: Add custom when under 5 (COW has 4, adding 1 = 5 total):

<animal animalType="COW" consumptionType="SERIAL">
    <!-- 4 existing vanilla food groups -->
    <foodGroup title="Total Mixed Ration" productionWeight="1.0" eatWeight="1.0" fillTypes="FORAGE"/>
    <foodGroup title="Hay" productionWeight="0.8" eatWeight="1.0" fillTypes="DRYGRASS_WINDROW"/>
    <foodGroup title="Silage" productionWeight="0.8" eatWeight="1.0" fillTypes="SILAGE"/>
    <foodGroup title="Grass" productionWeight="0.4" eatWeight="1.0" fillTypes="GRASS_WINDROW"/>

    <!-- Add custom 5th food group -->
    <foodGroup title="Oat" productionWeight="1.0" eatWeight="1.0" fillTypes="OAT"/>
</animal>

Option 2: Disable one + add custom (stay at 4 active):

<animal animalType="COW" consumptionType="SERIAL">
    <foodGroup title="Total Mixed Ration" productionWeight="1.0" eatWeight="1.0" fillTypes="FORAGE"/>
    <foodGroup title="Hay" productionWeight="0.8" eatWeight="1.0" fillTypes="DRYGRASS_WINDROW"/>
    <foodGroup title="Silage" productionWeight="0.8" eatWeight="1.0" fillTypes="SILAGE"/>
    <foodGroup title="Grass" productionWeight="0.4" eatWeight="1.0" fillTypes="GRASS_WINDROW" disabled="true"/>  <!-- Disable -->
    <foodGroup title="Oat" productionWeight="1.0" eatWeight="1.0" fillTypes="OAT"/>  <!-- Add custom -->
</animal>

⚠️ Don't do this (6 active entries will cause problems):

<!-- BAD: 4 vanilla + 2 custom = 6 active entries -->
<foodGroup title="Oat" productionWeight="1.0" eatWeight="1.0" fillTypes="OAT"/>
<foodGroup title="Barley" productionWeight="1.0" eatWeight="1.0" fillTypes="BARLEY"/>

Same principle applies to mixtures and recipes - keep active entries ≤ 5.

Speed Up Food Consumption (Testing/Fast-Forward)

Enable the consumption multiplier to make animals eat faster:

<consumptionMultiplier>
    <global multiplier="2.0" disabled="false"/>
</consumptionMultiplier>

Animals now consume food twice as fast. Useful for testing animal systems or speeding up gameplay.

Slow Down Food Consumption (Realism/Easy Mode)

Reduce consumption rate to make food last longer:

<consumptionMultiplier>
    <global multiplier="0.5" disabled="false"/>
</consumptionMultiplier>

Animals eat half as fast. Food supplies last twice as long.

How It Works

The mod integrates with Farming Simulator's animal food system through several mechanisms:

Schema Validation: Uses AnimalFoodSystem.xmlSchema to load and validate XML configuration files with the game's built-in schema
Lifecycle Hooks: Hooks into BaseMission.loadMapFinished to initialize after the game loads map data
Auto-Save Integration: Hooks into FSBaseMission.saveSavegame to update the XML file when you save your game
Merging: When loading, the mod:
1. Reads the game's current animal food system defaults
2. Loads your XML customizations
3. Merges them (XML values override, but new game content is added)
4. Applies the merged configuration to the game
5. Saves the merged result back to XML for next time
Direct System Modification: Updates g_currentMission.animalFoodSystem data structures that the game reads for animal behavior
Automatic Normalization: Mixture weights and recipe ratios are automatically normalized to prevent invalid configurations

Troubleshooting

Changes Don't Take Effect

Make sure you saved the XML file after editing
Verify the XML file is in the correct savegame folder
Check the game log for warnings about unknown fillTypes or invalid values

Game Log Shows Warnings

Unknown fillType 'XXX': You used a crop name that doesn't exist - check spelling or remove it
Failed to load XML: XML syntax error - check for missing quotes, unclosed tags, or special characters
AnimalFoodSystem not available: The mod loaded too early - this is usually harmless and will self-correct

Want to Reset to Defaults

Delete the aaf_AnimalFood.xml file from your savegame folder
Load your savegame
A fresh XML with current game defaults will be created

Multiple Mods Conflict

The merging system should handle most conflicts automatically. If you have issues:

The last-loaded mod's XML values will take precedence
Check if other mods modify the same animal food values
Try loading this mod last (rename to start with "zzz" if needed)

Consumption Multiplier Not Working

Make sure disabled="false" is set (the feature is disabled by default)
Check the game log for "Incompatible mod detected" warning - the multiplier is automatically disabled when conflicting mods like FS25_RealisticLivestock are active
Verify the multiplier value is between 0.01 and 100
In multiplayer, the multiplier only applies on the server - clients see the results but don't apply the hook themselves
