Atropine, a parasympathetic-blocking drug, has been found to reduce the volume of semen with little or no effect on the total number of spermatozoa ejaculated by the boar (Dziuk & Norton, 1962). Differences in composition of the semen from atropine-treated and control boars indicated that atropine suppressed the secretion of the urethral glands (Dziuk & Mann, 1963). In the bull, atropine has been found to reduce both the volume of semen and the number of spermatozoa per ejaculate (Signoret, 1962; Baker, VanDemark & Graves, 1963), whereas pilocarpine, a parasympathetic-stimulating drug, has significantly increased the volume of semen and total spermatozoa per ejaculate (Baker et al., 1963; J. P. Signoret, personal communication). The purpose of the present study was to determine the effects of pilocarpine
