The Veterinarian and His Role in Semen Shipment (Domestic, Foreign, Past, Present, Future)

Abstract

Importation of animals from foreign countries has made the growth of the livestock population possible in the United States. Cattle, horses, swine, sheep and birds imported from Europe since the time of the Pilgrims have provided the necessary genetic material to make the United States the world power in livestock production. As the development of herds progressed, seedstock of all types was shipped throughout the United States.
