The increasing successful use of artificial insemination is facilitated by a greater knowledge of the biology of the sow during her estrous period. The realization of the importance of establishing an adequate sperm reservoir in the oviduct at an appropriate time relative to ovulation has led to advances in the management of artificial insemination. In particular, knowledge of when a sow is lik...

Artificial insemination provides a method to inseminate a large number of females to a single sire that has been selected and proven to be an industry leader for economically relevant traits. Thus, genetic change in a herd can occur quickly through the use of artificial insemination. With natural service, herd bulls are also selected for economically relevant traits but are limited on the numbe...

Six years after that Committee published its findings, the situation may be reviewed in a more detached manner. I write as on...

Assisted reproduction is a relatively recent phenomenon. Aside from a few isolated examples, which apparently did not raise legal issues, assisted reproduction did not really come into its own until the practice of artificial insemination became common in the mid-twentieth century. Perhaps the earliest recorded example of a gestational agreement (surrogate mother) took place in biblical times.1...
