| Abstract: | 43 weeks old "Roman" Parent chicken''s eggs,according to eggshell colour,were divided into 4 groups (i.e.brown,spot brown,pink and yellow)and conducted 3 egg settings to hatch.The results of variance analysis showed that fertilization rate and hatchability of brown shell eggs were the highest (88.8% and 86.27%).those of spot brown shell eggs were the second (82.2% and 77.27%),pink were the third(78.1% and 74.84%),yellow were the lowest(74.17% and 67.27%)respectively in the hatching eggs.Healthy squab chicken rate of brown shell egg was the highest(10000),spot brown shell egg was 98.4%,yellow and pink were 97.7% and 95.2% respectively.For above reasons,brown shell eggs should be chosen completely for in hatching.Spot brown shell eggs might be selected if the stud eggs were not enough.Pink and yellow shell eggs, could not be selected for hatching eggs. |
