Abstract:
This study was carried out to investigate the effects of different levels of black seeds in diet of laying chickens on egg yield parameters, feed efficiency and egg shell quality. In this study, 24 week old laying hens were randomly distributed into four groups with four replicates of 5 birds each (20 laying hens per group) and were fed diets containing 0% (Group A, control), 1% (Group B), 2% (Group C), or 3% black seeds (Group D) for 49 days. Laying performance, egg quality and feed efficiency were evaluated. Eggs were examined for interior and exterior quality. Egg weights, yolk and albumen index, shape index, albumen weights, yolk weights, shell weights and shell thickness were measured in the daily collected eggs. Any level of black seed supplementation had no effects on live weight, egg production, feed consumption, feed efficiency, yolk index and albumen index. At the 6th and 7th weeks of the feeding study, weights of the eggs from the laying hens fed the Diet D were significantly greater than those from the laying hens fed the Diet A (p<0.05). And also the diet supplemented with 3% black seeds influenced the albumen weights of the eggs positively, compared to the control group (p<0.05). This study showed that supplementation of black seeds to the diet at the level of 3% increased egg weights from laying hens.
