Artificial insemination in swine.

This article analyses the advantages and disadvantages of artificial insemination with semen purchased from a center as well as from the herd boars on the farm. Intensive swine production could benefit greatly by adapting artificial insemination with herd boars, particularly from savings in labor and boar numbers. The techniques for semen collection, extension, and insemination are described, and sources for equipment given. Expected results of artificial insemination are quoted from experiments and international field experience.
