Realistic Livestock RM

A Farming Simulator 25 mod that replaces the default animal cluster system with individual animal simulation - each animal has unique genetics, health, and a full lifecycle.

Note: This documentation was generated with AI assistance and may contain inaccuracies. If you spot an error, please open an issue.

Key Features

  • Individual animals - Every animal is unique with its own identity, genetics, and history
  • Genetics system - Traits like productivity and size are inherited from parents with natural variation
  • Realistic breeding - Gestation periods, offspring genetics, breeding age limits, and pregnancy complications
  • Disease simulation - Species-specific diseases that spread, require treatment, and affect production
  • Lifecycle & aging - Animals age, peak in productivity, grow old, and eventually die
  • Herd automation - Set daily tasks that sell, buy, move, castrate, name, or inseminate animals for you
  • Saved filters - Build reusable searches to find and act on exactly the animals you want
  • Multiplayer support - Full server/client synchronization

Map Support

RLRM works on virtually any map out of the box - it does not need to be on a supported list. The maps below are the ones that add their own custom animal types or breeds; for those, the mod auto-detects the map and its installed version and loads matching support so the custom animals also get full genetics and breeding.

  • Hof Bergmann - Ducks, geese, cats, rabbits, alpacas, and quail fully supported with breeding, genetics, and reproduction
  • Witcombe - UK breeds (Jersey, Gloucestershire Old Spot, Texel, Suffolk, Blue Faced Leicester) fully supported with breeding, genetics, and reproduction. Hereford also gets a heritage breed profile. Adds rabbit keeping with breeding support.
  • Le Mechet - French breeds (Charolaise, Montbeliarde, Simmental, Vosgienne) with their map-native 3D models, fully supported with breeding, genetics, and reproduction

If a map updates to an untested version, you'll see a warning at game start - you're encouraged to report any issues.

Mod Compatibility

  • FS25_ExtendedProductionPoint (EPP) - Basic support for butchers using the EPP mod
  • Animal Packs - Third-party mods can add new breeds or adjust animal balance. See Animal Packs.
