Five individual male matings of line UNH 105 New Hampshires, in which all males and most females were either B22/B24 or B22/B26, produced 462 progeny that fell into six B complex genotypes: B22/B22, B24/B24, B26/B26, B22/B24, B22/B26, and B24/B26. Th

RESEARCH indicating an hereditary effect on nutrient composition of chicken eggs is limited (Taylor, 1960). Jackson et al. (1946), Asenjo (1950), Arroyave et al. (1957) and Mayfield et al. (1955) compared riboflavin levels in eggs from various breeds
