**3. Genetic improvement strategies or attributes of world breeding companies**

Breeding companies are formal institutions that pursue the genetic improvement of livestock as key goals. This process involves a conscious effort to improve the growth performance, reproductive, and fitness traits of the animals. This study is concerned with the breeding activities of poultry breeding industries. Their main targets comprised production of a meat type chicken, an egg type chicken or a dual purpose chicken. These processes require basically same strategies with limited differences, as they all follow same fundamental principles of genetics, which was revealed to the world by the study of Gregor Johann Mendel, the German Monk. No wonder then that most poultry breeding companies exhibit enormous affinity in breeding goals and attributes. Several characteristics of the world poultry breeding companies identified in this study are highlighted below.


farm began on an acres with two 40x400ft laying houses, an egg room, and a tenant house. It grew to 500 acres after 30 years.


more than 2 years, and parent stock is now available in limited quantities to customers around the world [64].
