| Abstract | ||
| This study was conducted in the Poultry Research Station Animal Resources Research department-state Board of Agricultural Research-Ministry of Agricultural in Abu Ghraib, which included one experiment to study the effect of supplementing different levels sources of Phytase enzyme to the Japanese Quail diets of birds on quality of eggs produced. Eighty hundred female quail birds (Coturnix Coturnix Japonica) 50 days of age, the experiment period from 31/8/2011 to 21/12/ 2011 (16 weeks). Quail birds distributed randomly to 16 treatments with various sources of Phytase, each source contain three levels divide to 16 treatments with 2 replicates (25 quail birds per replicate).The results of the second experiment showed, The treatment of T4C and T5C showed significant superiority (P<0.05) for the quality of yolk and white egg, while there are no significant differences between the treatments for relative weight of shell and SWUSA, when there are significant increase in shell thickness for the treatment of T6A. | ||
