Abstract

The aim of this study was to investigate the effect of artificial moulting on some egg shell quality parameters of produced eggs from two genotypes of aged laying hens. The experiment was conducted on group 1 ISA Brown 88 weeks old and group 2 Hisex Brown 91 weeks old hens. The egg weight during the period of starvation until the stopping of laying was higher in ISA Brown hens (64.38g) and lower in Hisex Brown (59.46g) (p 0.05).
