*Note*: Body weight variation represents the difference between the body weight at week 2/4 PI and the body weight at week 0 PI; relative body weight gain represents the percentage of the body weight variation relative to the initial body weight at week 0 PI. The different superscript letters within a row denote significant differences between different groups (*P* < 0.05). The different superscript letters in parentheses within a column denote significant differences between different time points (*P* < 0.05)*Abbreviation*: QX, QiXing rabbit breed propagated by the Sichuan Animal Science Academy, China; IRA, IRA rabbit breed; WPI, week post-infestation; Exp, experimentally infested animals; Con, non-infested control; SD, standard deviation
