Bison Egg & Breeding Calculator

Instead of laying eggs, the Bison carries its young through a gestation period. Gestation takes approximately 3 hours and 38 minutes at default rates.

The baby Bison takes approximately 1 day and 18 hours to fully mature at default rates - over a lengthy period. During the baby phase (0–10%), hand-feed it directly. From 10% onward (juvenile), it can eat from a Feeding Trough.

Mutations can add +2 levels to any stat and change colors. Stacking mutations across generations is the key to min-maxed breeding lines. Use the breeding calculator to plan food requirements, incubation timers, and maturation phases.

The hatched dinosaur, now a baby, needs constant attention and food placed directly in its inventory to survive, or a nearby Maewing to take care of its needs.

Juvenile

8:25:03

The dinosaur reaches the juvenile stage, where it can now eat from a feeding trough, reducing the need for direct feeding.

Adolescent

50% - 100%

10:31:18

The dinosaur reaches the adolescent stage, becoming more independent and able to follow you while continuing to grow toward full maturity.

Raising a baby Bison involves three maturation phases: Baby (0–10%) lasts ~253 min and requires constant hand-feeding. Juvenile (10–50%) spans ~17h - it can eat from a Trough now. Adolescent (50–100%) takes ~21h - continues eating from troughs, nearly fully grown.

Imprinting during maturation provides permanent stat bonuses. At 100% imprint, the Bison gains 30% bonus damage and resistance when ridden by the imprinter. You'll be asked to cuddle, walk, or feed specific kibble at regular intervals during maturation.

Planning a mass raise? The Bison raising calculator breaks down food needs per phase so nothing goes to waste. Expect ~253 minutes of active care during the Baby phase before it graduates to trough-feeding as a Juvenile.

Adjust the dino count to calculate food for multiple Bison babies at once - essential for batch breeding operations. Match your food choice to your play schedule - longer spoil timers mean less babysitting.

During the Baby phase (0-10%), you must hand-feed or use a Maewing to nurse. From Juvenile (10%+), dinos can eat from a Feeding Trough on their own. Use Preserving Salt in troughs to double spoil times.

The Bison, a tamable, herbivore creature in ARK: Survival Ascended, is a notable presence across multiple maps.

Health-wise, the Bison sits at 800 base, making it solidly tanky. With 100% base Melee Damage, the Bison has decent hitting power. Stamina sits at 500 base, providing respectable staying power. Weight capacity starts at 650, giving it an enormous weight pool.

Taming the Bison requires rendering it unconscious first - use Tranq Arrows, Darts, or Shocking Tranq Darts to apply torpor. Superior Kibble is the most effective food for taming, offering the highest affinity per feeding.

After taming, the Bison is a practical workhorse - it can both gather and haul resources efficiently. Breeding is via live birth rather than eggs, simplifying the process. A wild Bison is worth 4 base experience when killed. It can be cloned at a Cloning Chamber for 0.39 Element plus 0.01 Element per level.
