Abstract
This study was conducted at Department of Animal production, Faculty of Agriculture and Forestry, Mosul University from 16/12/2013 to 16/5/2014. This study had been done to determine the effect of adding Phytase enzyme by 300 g / tonne feed in reproductive efficiency and quality of eggs in broiler breeder Rose strain. A total of 240 chickens and 40 roosters at the age of 42 weeks. They were randomly assigned to eight treatments in tow replication for each 12 chickens and 2 roosters in each replication. The results showed that there were no significant differences (0.05> P) in egg yolk index, albumen index and haugh units and egg shape indicator. While affected significant eggs shell thickness. The results of adding the enzyme to the diets of low calcium, phosphorus and both of them were not affected significantly (0.05> P) the fertility and hatchability of total eggs and fertilized eggs, while significantly reduced the embryos mortality rate in the positive control treatment.
