Although there are numerous estimates of the heritability of egg weight in chickens, there is very little information available concerning the heritability of this character in turkeys. Blow and Glazener (1954) estimated the heritability of egg weight in Bronze turkeys from the phenotypic correlations between paternal half sibs, phenotypic correlations between full sibs and from the intra-sire regression of offspring on dam. The average of the three estimates was .555 for egg weight in February. Apparently there are no other reports on the heritability of egg weight in turkeys. Therefore, the present study was undertaken to provide additional estimates on egg weight in turkeys. EXPERIMENTAL MATERIAL AND METHOD OF ANALYSIS The present study was based on egg weights obtained on pullets of single-male matings of The Pennsylvania State University strain of White Holland turkeys during 1953, 1954 and 1955. The history, selection emphasis and management of this flock has been …
