Geometric mean isotype-specific and neutralizing Ab titers (GMTs) to Indiana RVA (G6P[5] strain) in serum collected weekly (lines). a) G1: calves fed with colostrum (C) followed by bovine RVA egg yolk supplemented milk with a final Indiana RVA IgY Ab titer of 4096 for 7 consecutive days once diarrhea appearance; b) G2: calves receiving C followed by non-supplemented RVA Ab free milk; c) G3: colostrum deprived calves receiving RVA Ab free milk. All calves were orally inoculated with virulent Indiana RVA strain at 0 PID. Statistical analysis of the Ab titers in serum was performed by ANOVA followed by DGC multiple comparison test through time, p < 0.05. The “–” indicates no significant differences between groups.
