Traits	Mean	SD	CV, %	Min	Max
AFE	174.75	7.94	4.55	159	200
EN1	16.15	6.93	42.89	1	36
EN2	25.42	3.92	15.41	2	51

EN4	28.21	8.71	30.86	1	47
TEN	122.94	23.51	19.12	42	180

AFE represents age at first egg; EN1, EN2, EN3, EN4, and TEN represent total egg numbers in each of the five stages (from onset of laying eggs to 195 d, from 196 to 227 d, from 228 to 307 d, from 308 to 354 d, and from the onset of laying eggs to 354 d, respectively); SD represents standard deviation; CV represents coefficient of variation
