The Pedigree Basis of Selecting Breeding Males for High Egg Production^*

Massachusetts Agricultural Experiment Station

Abstract

Conclusions: The practical importance of the selection of breeding males in flocks bred for egg production is much appreciated by poultrymen. Some believe that the ability of hens to make good egg records is more largely traceable to their male ancestors than to their female ancestors. At any rate, the fact is well recognized that the male breeders must be carefully considered in developing a flock uniform for high production. Since actual egg production can only be measured by the females of the flock, other criteria must be employed in choosing the males. Some breeders prefer to use cockerels while others make use of yearling or older cocks for breeding. The merits or demerits of these practices will not be discussed in this paper. The following discussion of data available at the Massachusetts Station will have a bearing on methods of selection that may be. applied to cockerels and cocks and others that apply only to cocks.
