Abstract :
This study was conducted to evaluate the effects of different mineral premixes in performance of laying hens. This experiment was conducted with one hundred and forty four laying hens from 24 to 34 weeks in a completely randomized design. Mineral premixes include minerals recommended by Hy-line Company for commercial production of laying hens (control). Darosazan mineral premix, Tolidaru mineral premix and Aras Bazar mineral premix were used for 10 weeks. Results of this experiment showed that performance of laying hens was significantly affected in different experimental groups. Using of mineral that recommended by Hy- line company for commercial production of laying hens caused significant increasing in egg weight and egg mass (p < 0.05). Egg shell thickness and egg quality increased significantly by using of mineral recommended by Hy- line company for commercial Hy – Line W – 36 laying hens (p < 0.05).
