Kinetics of increases in skin thickness following intradermal inoculation with ovalbumin of the 14 immunized cows.

<p>(A) Increases in skinfold thickness calculated by subtracting the thickness value measured before inoculation from the values measured after injection. (B) Spearman correlation between Peak SCC and skin test values measured at 24 or 48 h post-inoculation, considering either the 14 immunized cows (All) or only the 10 responders (R). ns: not significant (p > 0.05).
