ABSTRACT
This study investigated the influence of different particle sizes of limestone in layer diets on egg production and eggshell quality from 18 to 28 weeks of age. Limestone consisting of small (.05) egg production and egg shell quality at 24 weeks of age. Feed intake, body weight, egg production and egg weight increased over time. The present results suggest that the influence of dietary limestone particle size distributions at a later stage of the laying period on egg production and egg quality needs further investigation.
