This study was conducted at one of the fields of Al-Wardiya district in Babylon Governorate where the field experiment lasted 16 weeks, with four periods of four weeks each. This experimental field was started from 20/ 11/ 2023 to 10/ 3/ 2024 in order to study the effect of adding different levels of Plantago ovata seeds powder to the diet of laying hens on their productive performance. A total of 105 white Lohmann laying hens, 65 weeks old, were used in the experiment, and the production period was divided into four experimental periods which are (66-69) weeks, (70-73) weeks, (74-77) weeks, and (78-81) weeks of the laying hens age. The feed was provided according to the standard requirements that mentioned in the managements guide of Lohmann white layer. The laying hens were randomly distributed into five treatments (21 hens per treatment), where each treatment included three replicates with seven hens per replicate. The treatments were classified as follows: T1: a control group free of any addition, T2, T3, T4 and T5: basal feed with 10, 15, 20 and 25 gm of powdered Plantago ovata seed /kg feed respectively. The data were analyzed using a completely randomized design and the averages were compared using Duncan’s multiple range test. Results showed a significant improvement (p≤0.05) in the percentage of egg production, cumulative number of eggs, egg weight, egg mass, and feed conversion factor in comparison with the control treatment. In particularly, T5 resulted in the most important outcome of this study.
