Selective Breeding
Selective Breeding is a livestock technology that increases Food gathering from herdable animals by 25% at the applicable livestock buildings. It improves an animal-based economy rather than hunting or ordinary Farm gathering in general.

Effect
The effect applies to herdable animals at the Livestock Pen, Farm, Village, Livestock Market or Hacienda where supported by the civilization and version. The animal must be assigned to the relevant structure and gathered under the technology’s rules. Access to the technology depends on the selected civilization’s building and research tree.
Research condition
Available in the Exploration Age at Livestock Pen (Europeans and the United States) , Farm (Native Americans) , Village (Chinese) , Livestock Market (Africans) , Hacienda (Mexicans). Research time: 30 seconds. Cost: 75 wood, 75 coin. Civilization-specific building access can vary.
Research decision
Research it when a meaningful share of the Food economy will come from herdables and workers or livestock can use the improved rate for enough time. If most Food comes from Hunts, the upgrade may not repay its cost. Protect the livestock area so the gathering benefit can continue.
Apply the bonus to the right food source
The 25% increase concerns Food gathered from herdable animals at supported livestock buildings, not ordinary hunts or every form of Food gathering. Ensure the animals are assigned to an eligible site and can be worked for long enough to repay research. If workers primarily hunt, adding livestock infrastructure may be a larger commitment than this upgrade warrants.
