Histologic and morphometric alterations in the parotid salivary gland of 14 male Gyr Zebu were carried out coupled with a histochemical study of the mucosubstance of this gland. Animals ranging in age from 1–2 months to 17–21 months were utilized. The gland was found to represent a compound tubular gland which is entirely serous in older animals, but with mucous endpieces in younger animals. The morphologic and morphometric data indicate that this gland reaches anatomic maturity at about 13 months of age, an age which correlates with the onset of spermatogenesis in this species. The histochemical nature of secretions is discussed for various components of the gland.
