Mean numbers of bovine RVA ASC per 5 × 10⁵/MNC obtained from GALT at 21 PID. G1: calves fed with colostrum (C) followed by milk supplemented with bovine RVA egg yolk with a final Indiana RVA IgY Ab titer of 4096 for 7 consecutive days after diarrhea appearance; G2: calves receiving C followed by non-supplemented RVA Ab free milk; G3: colostrum deprived calves receiving RVA Ab free milk. All calves were orally inoculated with virulent bovine RVA (Indiana G6P[5] strain) at 0 PID. For each tissue, when comparing mean ASC numbers of the same isotype, among treatment groups: different letter indicate a significant difference (Kruskal–Wallis rank sum test, p < 0.05). n = number of calves in each group. Error bars indicate SD. The “–” indicates no significant differences between groups.
