Excavations by the Thai-American Thailand Archaeometallurgy Project (TAP in the Khao Wong Prachan Valley in the 1980s and 1990s produced a large assemblage of animal bones from the multi-component site of Non Pa Wai, a site devoted to the smelting of local copper ores. Study of the animal bones indicates that subsistence strategies changed over the times of occupation. Significant reliance on hunting and fishing occurs during the earlier Neolithic and Bronze Age occupations. Management of dogs and pigs for food occurs during extensive production of copper, in the early centuries CE. Excavations at contemporary sites including Man Bac and An Son in Vietnam, and Ban Non Wat, in Thailand, have provided comparative contexts to examine dietary breadth and subsistence from a regional perspective. These analytical opportunities enlarge our understanding of the variability in animal husbandry strategies as subsistence articulates with other facets of the domestic economy, such as agriculture and craft production. Representative assemblages from comparable sites elsewhere in mainland Southeast Asia allow us to examine animal husbandry on multiple scales.
