Research is currently focused on utilizing artificial insemination (AI) to enhance livestock productivity and genetic quality. By using semen from superior males, farmers can access desirable traits like improved growth and milk production without maintaining breeding bulls on-site.

In Nebraska, researchers at the University of Nebraska-Lincoln Panhandle Research, Extension, and Education Center, in collaboration with 2Bar Ranches, are studying methods to optimize breeding efficacy in beef heifers. The investigation is examining whether multi-sire semen—combining sperm from three different bulls—can increase pregnancy rates compared to single-sire semen, while also evaluating the performance differences between fresh and frozen semen.
