Egg Shell Quality Assessment–Do We Need Multiple Records?
Abstract
The objective of this study was to estimate repeatability within and between ages for dynamic stiffnessin two lines of layer chickens in order to verify if multiple records are necessary to adequately describe a bird’s genetic merit for egg shell quality.Repeatability was low across ages to moderate within age,which suggests that for accurate evaluation eggs should be collected at different stages of laying cycle,with additional benefit from analyzing more than one egg within age.
