The productivity and resilience of the indigenous chickens in the tropical environments: improvement and future perspectives

The poultry population in Africa is mostly composed of local or indigenous chickens appreciated for the unique taste and texture their meat. However, with ever-increasing growth, free-range backyard farming system no longer adapted to supply people protein requirements. Crossbreeding hens an improved rooster weakens thermotolerance disease resistance offspring African areas. In this context, available breeds need be preserved. improvement productivity should actualized through implementation a sustainable production programme that simple less expensive farmer, taking into account: feeding, habitat chicken care. Scientific research invest more time on identification characterization all ecotypes allowing us know performances nutritional needs. Feeding locally resources, vaccination use medicine requiring training farmers are essential perspectives. This paper focused resilience various tropical environments some factors improve birds. For this, critical analysis was made based data birds from databases.
