Summary In non‐pregnant adult sheep biological ‘half‐lives’ of IgG 1 and IgG 2 were approximately 8 days with those for lambs slightly less than 7 days. In contrast, in late pregnant ewes forming colostrum the ‘half‐life’ of IgG 1 was only 3·7 days. This value was significantly less (P < 0·01) than for IgG 2 and less (P < 0·001) than the value for IgG 1 in non‐pregnant animals.
