DG: Natural Reproduction
by dasikigaijin
DG: Natural Reproduction changes how farm animals breed and gather, so cows, sheep, pigs, goats and horses form herds that move across a pasture.
What it does
Passive animals form social herd clusters on their own, and the oldest healthy adult in a herd becomes its leader and guides the group across the pasture. The herd grazes on fresh grass near water and shaded tree canopies. Breeding is no longer a manual task: animals reproduce by themselves when conditions allow, and a pregnancy runs for a realistic gestation period, shown by subtle heart particles.
Fertility depends on the biome. Temperate meadows, lush plains and river valleys give bonuses, while frozen tundras and arid deserts reduce how often animals reproduce. Herd behavior runs through HerdSocialHelper and FollowHerdLeaderGoal, and local animal counts come from SpatialBreedingCacheHelper, which avoids expensive entity scans across whole chunks. The mod requires Dasik Library and Fabric API, and it runs on the server alone.
The mod is open source under the GNU General Public License v3.0 or later, and the source code and wiki are public. It is published for Fabric only, across five game versions: 1.20.1, 1.21.1, 1.21.11, 26.2 and 26.3, with 1.4.32+26.3 for 26.3 as the latest file, dated 2026-10-11.

What the author says
In vanilla Minecraft, animal life is strangely artificial and static. Cows, sheep, pigs, and chickens stand frozen in cramped pens, completely incapable of breeding, thriving, or expanding unless a player manually walks up and hand-feeds them wheat or seeds. The moment you leave your farm, the ecosystem grinds to a…
