Erythrocyte lifespan in dwarf and normal pullets from growth selected lines of chickens.
Mean erythrocyte lifespan was estimated, using a 51Cr tagging procedure, in dwarf and normal sisters from lines selected for high and low body weight at eight weeks of age. Correlations between body weight, packed cell volume and erythrocyte lifespan were not significant. Significant differences were found among genotypes for body weight and packed cell volume, but not for lifespan of erythrocytes.
