Breeding and genetics--historical perspective.
This paper is a review of selection methods that have been used in commercial breeding of table egg stocks, broilers, and turkeys, based on the author's experience. In addition, a number of historic developments that have shaped or influenced the selection process are listed and the significance of each is discussed. The merits of mass selection are noted and compared with the multiple forms of family selection, e.g., full or half sibs, progeny testing, and recurrent methods. Each of these methods is believed to have nearly universal application in applied breeding programs being practiced today. This review concludes that a combination of individual and family selection practices aimed at improving multiple traits simultaneously is required to remain a successful supplier of breeding stock to the current commercial industry.
