Effect of Prenatal heating treatments (SPIDES and/or TC) on egg weight loss % during the whole incubation period and egg weight at E18.
| SPIDES (S) | Significance | |||||
|---|---|---|---|---|---|---|

a,bOverall means with different superscripts within a row are significantly different (*P ≤ 0.05, **P ≤ 0.01 and NS nonsignificant).
SPIDES short period of incubation during egg storage, S0 eggs were stored for 20 days without SPIDES, S1 eggs were stored for 20 days and exposed to heat on the 5th, 10th and 15th day of storage, DOS day of storage.
