1Number of piglets suckling and lactation length were used as a covariate in the analysis

2Parity effect was included in the model

3Parity effect and treatment effect was included in the model

a, bWithin a row, values with no common superscript differ significantly (P < 0.05)

x, yWithin a column, values with no common superscript differ significantly (P < 0.05).
