摘要：

A low-input and simple liquid semen vaginal artificial insemination (AI) protocol developed at Virginia State University was evaluated on four commercial small farms during the peak of the breeding season. Pregnancy rates of 20%-70% were achieved. These results suggest that use of the described AI protocol would provide an effective means of enhancing the genetic potential of herds and maximizing profits for small-scale sheep producers. Cooperative Extension personnel can promote the use of liquid semen vaginal AI as a practical and effective tool for genetic improvement and facilitate its use among interested farmers.
