¹RSD, residual standard deviation.

²Fixed effects of the variance analysis model, with initial parity of the sow as a covariate.

³From days 3 to 106 of gestation, the following are all followed in the gestating room.

a, b, c, and d values within a row that do not share a common superscript are significantly different (P ≤ 0.05).

CF, conventional feeding, PF, precision feeding.
