Effect of age on the weight of 1 d egg (lsmeans ± SE) and stored 21 d eggs (lsmeans ± SE) of each genotype 1. Different letters among similar columns (storage time) indicate different values. a, b, c: p < 0.05; A, B, C: p < 0.01. *: p < 0.05 and **: p < 0.01 indicate different values between columns of different storage time per each age. ns: no significance. 1 Genotype: ER: Ermellinata di Rovigo (a); RM: Robusta maculata (b); HB: Hy-line brown (c); HW: Hy-line white (d). Observations (n) per age (at 1 d; at 21 d): ER (30, 30, 24, 30; 30, 24, 18, 20), RM (25, 22, 22, 24; 20, 16, 20, 20), HB (30, 30, 24, 30; 29, 25, 25, 25), HW (30, 30, 24, 30; 28, 24, 24, 24).
