| Abstract | ||
| This experiment was conducted at the Poultry Farm of College of Agriculture, University of Baghdad by using 150 Lohmann hens and 15 Lohmann roosters, 24 weeks old. Birds were randomly allocated into five treatments of 30 hens and 3 roosters each. Each treatment was constituted of three replicates with 10 hens and one rooster each. Treatment groups were as follows: Control group (C), T1 and T2 represent the supplementation of anise powder to ration at levels of 2 to 4 Kg / ton of diet, respectively, and T3, T4 represent the addition of anise oil to the birds ration at the levels of 250 or 500 ml / ton of diet, respectively. Characteristics included in this experiment were: mean body weight, feed counsumption, rate of egg production, egg weight, egg mass, feed conversion ratio, cumulative egg production, and percentage of fertility, hatchability from total eggs, hatchability from frtile eggs, and embryonic mortality. Results revealed that dietary supplementation with different levels of anise seeds or oil resulted in significant improvement in the means of egg production, egg weight, egg mass, feed conversion ratio and cumulative egg prodction during the most weeks of experiment and significant improvement in the total means of egg production, egg weight, egg mass, feed conversion ratio, cumulative egg production and percentages of fertility, hatchability from total eggs, hatchability from fertile eggs and livability. However, there were no significant differences between experimental treatments with respect to mean body weight and feed consumption during most weeks of experiment and as regards total mean of body weight and cumulative feed consumption. In conclusion, the addition of anise seeds or oil to laying hens ration resulted in clear improvement in many aspects of productive performance for these birds. Therefore, anise seeds or oil can be used as one of important nutritive supplements to the laying hens diet for improving the reproductive efficiency for these birds. | ||
