2WK, weight at 2 weeks of age; 3WK, weight at 3 weeks of age; 6WK, weight at 6 weeks of age; 9WK, weight at 9 weeks of age; G26, weight gain from 2 to 6 weeks of age; G29, weight gain from 2 to 9 weeks of age; NA, nasal-anal body length; Tail, tail length. Values are expressed as least square means (LSMEANS) ± SEM. LSMEANS in bold are significantly different than the control (HGC) (critical P < 0.005) after Bonferroni correction within each sex.
