FS25 Realistic Livestock RM V1.4.1.0
Replaces FS25’s simple animal clusters with individually tracked animals, each with unique genetics, breeding, diseases, and production traits. This is a maintained version of Arrow-kb’s Realistic Livestock mod.
Every animal is tracked separately with its own identity, genetic makeup, health status, and production output. Genetics are inherited through breeding, diseases can spread and require treatment, and production is driven by each animal’s individual traits. Everything is managed from the RL Menu, a dedicated tabbed interface for browsing, trading, moving, filtering, and automating your herds.

Supported Maps & Packs
RLRM works on virtually any map out of the box. It does not need to be on a list. The maps below are special only because they add their own custom animal types or breeds, which need built-in support for those extras to get the full RLRM treatment, including genetics, breeding, and reproduction. On any other map, the standard animals just work.
Maps
- Hof Bergmann () – ducks, geese, cats, rabbits, alpacas, and quail with full breeding support
- Witcombe () – UK breeds, Jersey, Gloucestershire Old Spot, Texel, Suffolk, and Blue Faced Leicester, with full breeding support; Hereford heritage profile
- Le Mechet (https://www.farming2015mods.com/farming-simulator-25-mods/fs-25-maps/fs25-the-mechet-v1-0-0-3/) – French breeds, Charolaise, Montbeliarde, Simmental, and Vosgienne, with full breeding support. NOT compatible with Cow Breeds Pack unless you use the latest development version, as both replace the cow husbandry config
Animal Packs
- Cow Breeds Pack for RLRM (https://github.com/ConGan98/FS25_CowBreedsRLRM) – additional cattle breeds

Changelog
- V1.4.1.0
You can now vaccinate animals for some diseases from the Diseases dialog, newborns of an immune mother start life protected, and footrot joins the diseases for cattle, sheep and goats. Saved filters come back to the trailer Transfer tab, starving animals lose health more slowly, and old-age and accident deaths no longer rise with longer months.- Vaccination, from the Diseases dialog, protects cattle against BRD, pigs against PED, sheep and goats against pulpy kidney, and cows and female goats against mastitis.
- Protection from the mother, piglets, lambs, and goat kids born to an immune mother start life protected.
- Footrot, a new disease for cattle, sheep and goats, with treatment and a vaccine.
- Filters on the trailer, cycle your saved filters on the Transfer tab to load or unload only the animals you want.
- A clearer Diseases dialog, the most urgent disease comes first, every row has a coloured icon, and a treatment asks before it starts, resumes, or stops.
- Fairer health and death odds, starving animals lose health more slowly, good health genetics now help, and old-age and accident deaths no longer rise when using more days per month.
- V1.4.0.0
This is the disease release. The disease system has been rebuilt from the ground up: an illness now runs day by day, can hide for a while before any symptoms show on harder settings, and is tuned by a five-level difficulty setting. Four new diseases join the five you know, among them colic, the first disease for horses. A sick animal can no longer be sold or sent to the butcher while it shows symptoms. Treat it, or cull it from the Diseases dialog. Updating an existing save? Every disease, immunity, part-way treatment, and CVM carrier in your save is cleared on first load, so your herd starts out healthy, and the Diseases setting becomes Normal, or Off if diseases were off.- Nine diseases, avian flu (HPAI), BRD, pulpy kidney, and colic join mastitis, CVM, foot and mouth, PED, and avian flu (LPAI).
- A hidden phase, on Hard and Very hard, a newly infected animal looks healthy for a while before its symptoms show.
- Five difficulty levels, Off, Easy, Normal, Hard, and Very hard, plus a Choose Diseases list to switch single diseases off.
- Treat or cull, a sick animal cannot be sold or butchered while it shows symptoms, by you or the herdsman; the new Cull button removes it for a share of its value.
- Illness hits more than the milk yield, growth, breeding, eggs, wool, and manure all suffer while an animal is ill.
- Every disease infection, immunity, part-way treatment, and CVM carrier in your save is cleared on first load. The new disease records cannot read the old ones. Your herd starts out disease-free and CVM-free.
- The Diseases setting becomes a difficulty level. An existing save lands on Normal, or Off if diseases were off. The Disease Chance setting is gone.
- A sick animal that shows symptoms can no longer be sold or taken to a butcher, by you or by the herdsman. A herdsman sell rule for animals with any disease now sells none. Switch it off or change its filter.
- Foot and mouth treatment is now a one-month course like every other disease, instead of three months.
- V1.3.2.1
- Fixed newborn rabbits on the Witcombe map never gaining health, so many of them died at their first day change. Rabbits of every age now eat and drink the amounts the Witcombe support sets.
- Corrected the disease guide’s spread ratings. Foot & Mouth is the one disease that sustains an outbreak on its own, while PED and avian flu outbreaks usually burn out.
- Documented in the pack-creation guide which curves accept decimal values. Food, water, and straw do, every other curve reads whole numbers only.
- Enabled animal packs to set decimal food, water, and straw rates, such as 0.2. They were previously cut down to whole numbers.
