Abstract
The following conclusions were drawn from results secured from various matings of Rhode Island Red sires, whose dams laid a min. of 200 eggs each during their 1st laying yr., mated to Rhode Island Red dams each of which laid a min. of 200 eggs during her 1st laying yr.; lst-yr. egg production of the dam could not be used as a criterion of her breeding potentialities; lst-yr. egg production records of the dams should not be used in determination of a sire''s breeding index; mean egg production of full sisters could not be used as an index of breeding potentialities of any of the full sisters; mean egg production of each sire''s daughters serves as the most readily available index of a given sire''s breeding potentiality; mean egg production of daughters of the mating of a given sire and a given dam is the index of greatest value in determining breeding potentiality of an individual sire or dam.This publication has 1 reference indexed in Scilit:
