Effect of Uniformity of Eggshell Thickness on Eggshell Quality in Chickens
Numerous parameters have been proposed to evaluate eggshell quality in order to reduce losses from damaged eggshells. The uniformity of eggshell thickness (UET), as a newly proposed parameter, is defined as the reciprocal of the coefficient of variation
