ABSTRACT Village chickens are ubiquitous in smallholder farming systems, contributing to household, local and national economies under diverse environmental, economic and cultural settings.


However, they are raised in challenging environments where productivity is low while mortality is high. There is much interest in utilizing indigenous genetic resources to produce a chicken


that is resilient to its environment, while at the same time providing the basis of an economically sustainable enterprise. Globally, however, a wide variety of interventions have so far


proved unable to deliver sustainable improvements. Here we show that regional differences in trait preferences and parasite burden are associated with distinct chicken gene pools, probably


in response to interactions between natural and human-driven (economic and social) selection pressures. Drivers of regional differences include marketing opportunities, cultural preferences,


agro-ecologies and parasite populations, and are evident in system adaptations, such as management practices, population dynamics and bird genotypes. Our results provide sound


multidisciplinary evidence to support previous observations that sustainable poultry development interventions for smallholder farmers, including breeding programmes, should be locally


tailored and designed for flexible implementation. Access through your institution Buy or subscribe This is a preview of subscription content, access via your institution ACCESS OPTIONS
