Table 2. Survival percentage (%), early, mid and late mortality (%) and infertility (%) of the eggs of the control, sham and albumen-deprived group.

Item (%)	control	sham	albumen-deprived	P-value
Survival	87.7a	69.3b	38.1c	<0.001
Early mortality	7.0a	25.4b	55.7c	<0.001
Mid mortality	0.0	0.0	0.5	NS
Late mortality	5.3	5.3	5.7	NS
Infertility	2.6	4.2	2.3	NS

Number of fertile eggs in control (n = 144), sham (n = 144) and albumen-deprived group (n = 240).

^a–cWithin a row, treatment means with different superscript are significantly different (P<0.001). P-values of effect of treatment are added in a separate column.

Survival (%) =  (number of hatched chicks/number of fertile eggs)*100

Mortality (%)  =  (number of dead eggs/number of fertile eggs)*100

Infertility (%)  =  (number of infertile eggs/total number of set eggs) *100
