Consumer-driven reproduction

摘要

This vet promotes reproductive technologies for consumer-oriented beef production. Brad Stroud may be a small town veterinarian, but his expertise in the development and use of bovine technologies is widely acclaimed in the international arena. The Weatherford, TX, native produced the first live commercial calves from a clinically infertile cow utilizing a procedure he developed called the "Modified GIFT (Gamete Intrafallopian Transfer) Technique" back in 1988. This involves harvesting ova - unovulated eggs - with a laparoscope via a flank puncture, then surgically transferring them into the oviducts of reproductively healthy females so normal fertilization and embryonic development can take place. About 40 live calves were born as a result of thisprocess. Logistical barriers, however, discouraged Stroud from pursuing further commercial development. And, in 1991, Stroud was among the first veterinarians to commercially produce "test tube" calves utilizing in vitro fertilization.
