Abstract

This study was conducted to compare the effect of adding different levels of olive pomace on some productive traits of ISA Brown laying hens, at the field of laying hens of the Agricultural Research and Experiment Station, Agriculture College, Al-Muthanna University, from 7/6/2022 to 4/9/2022 for a period of 12 weeks. A total of 72 hens, 18 weeks old, ISA Brown laying hens were used, it was randomly distributed to four treatments distributed to 3 replicates ( 6 laying hens each replicate), the treatments were as follows: T1: the control treatment. As for the treatments T2, T3 and T4, dried olive-pomace powder was added at levels of 1.5, 3 and 4.5% to the diet. The results indicated a significant superiority on the egg production and egg mass with a significant improvement in the feed conversion factor in all treatments of olive-pomace powder compared to the control treatment, there were no significant differences on the average egg weight among all experimental treatments.
