COMPARISON OF SOME EGG QUALITY CHARACTERISTICS IN LOCAL STRAINS IN IRAQ .

Abstract

The aim of this study is to compare some egg characteristics among three local strains chickens in Iraq (broiler dam line Fawbro ( CD ) and strains of brown (BR) and Barred (BA) ) . The eggs were collected from 75 chickens of each strain at 28 weeks age. The study included assessment of recipes egg quality as following: Egg weight (g), yolk weight(g) , yolk height ( ml. ) , Albumen weight (g) , Albumen height ( ml. ) , Shell weight , shell thickness , and from this parameters the yolk index .The result indicated that there were a significant ( p<0.01 ) effect for the genotype of the strain ( CD) in compare with strain ( BR ) and strain (BA ) in egg weight , yolk weight , albumen height , yolk ratio , albumen ratio and shell weight . while there were no significant differences among the three strains in yolk height , shell thickness and yolk index.
