This study investigated the effect of different levels of zeolite in laying hen (Silver Montazah) diet and litter on productive performance, egg quality criteria, and economics during the second stage of production (40-56 wk of age). An experiment with a 3 × 4 factorial design was performed to study the effects of four levels of zeolite (0, 10, 15, and 20 g/kg feed) in the diet and three levels of zeolite (0, 1.5, and 2 kg/m2 ) in the litter. Adding zeolite to diet and litter significantly improved final BW and BW change, egg number, egg weight, egg mass, laying rate, feed consumption (FC), and feed conversion ratio (FCR), as well as egg quality criteria when compared to the unsupplemented group...
