Abstract:

This study was conducted to determine the effects of organic acids supplementation on body weight, egg production, feed consumption, feed efficiency and egg weight in laying hens at different cage density. In this experiment, 88 Bovans laying hens aged 40 weeks old, were divided into 4 groups with 4 replicates. The birds were placed in to 50x40x40 cm cages in groups of 4, and 7 in the case of cages where cramped conditions were provided. The control groups were fed basal diets and treatment groups were fed basal diet supplemented with 0.2% organic acid (Sal-tech) for 60 days. At the end of the study, cage density did not influence the performance of hens, and greatest live weight, feed consumption, egg production, and egg weight were obtained with hens kept within a standard cage density and fed a diet containing organic acid. There were no differences between the hens kept in a higher cage density (7 birds/cage) consumed eigher organic acid or basal diet
