ABSTRACT
The Artificial Insemination (AI) industry in 1980 is a dynamic and healthy industry with active competition. Approximately 60% of the dairy cows in the United States are bred by artificial insemination. The AI industry has a trade association, the National Association of Animal Breeders (NAAB), to coordinate activities of its members. The industry is largely self-regulated with Certified Semen Services monitoring compliance of members with minimum standards for identification, record keeping, disease control, and semen quality.
Artificial insemination has become the focal point of genetic improvement of dairy cattle. The widespread use of bulls by AI created a breeding structure that has enabled development of accurate sire evaluation as a basis of selection of sires for widespread use in the next generation. AI also has reduced the spread of venereal disease by bulls. The milk production of the average dairy cow has more than doubled since the first AI organization began operation in 1938.
