Normal dairy cows were “stressed” by simple isolation from the herd and chasing by a dog. Quarter milk samples showed, in some instances, a marked rise in cell count, the quarters responding having, in general, a history of infection though the counts were normal before stressing. An injection of 50 units of ACTH produced similar though less marked effects.
