Abstract: A deterministic bio-economic,model,was,developed,to support breeding,of indigenous chicken and used,to evaluate biological and,economic,variables that characterise,indigenous,chicken,(Gallus domesticus)production systems in Kenya. The systems were defined on the basis of the feeding regime, levelof confinement and healthcare provided and included; confined full ration system, where the chicken areconfined all the time and provided with commercial feed and proper healthcare; semi-intensive system, where the chicken are confined part of the time and given crop residues and kitchen waste, with no healthcare; and free range system, where the chicken are left to roam around the homestead picking whatever feed,resource,they get and,without healthcare. The input parameters,are divided into four categories: biological variables which include animal traits, managemental variables, nutritional variables and economic,variables. These parameters,assume,typical indigenous,chicken,production,in Kenya . However, t he input parameters may be adjusted to suit specific situations and also assess the biological and economic,performance,of various production systems,of other domestic,avian species. The model’s ability to simulate live weight changes, feed intake of various chicken categories, revenues, cost and profitabilityof the three production systems,is illustrated. The bio-economic models,can be used to develop breeding goals and estimate economic,values for the genetic improvement,of indigenous chicken. Key words:Indigenous chickens, production systems, bio-economic model, Kenya,
