Experiences in Artificial Insemination of Beef Cattle in North Queensland
نویسندگان
چکیده
Artificial insemination was used in an attempt to breed three groups of Brahman cross cows on two properties in north Queensland. On one property the attempt was abandoned due to low incidence of detected oestrus in lactating cows. On the other property calving rates following insemination were 20.8% and 16.4% over two years. Vibriosis was one cause of low fertility. Semen was collected satisfactorily from properly prepared Santa Gertrudis bulls using an artificial vagina. Electroejaculation proved unreliable. The results are discussed in terms of the problems associated with artificial insemination of beef cattle.

Large-scale artificial insemination services in Queensland date from 1955. In that year a bull-proving project was inaugurated for the purpose of locating dairy sires of outstanding genetic merit from Queensland studs. The project requires the artificial insemination of at least 1,000 cows each year in the Nambour region of south-east Queensland. In September, 1957, an artificial insemination c...

Introduction Estrous synchronization and artificial insemination (AI) are reproductive management tools that have been available to beef producers for over 40 years. Synchronization of the estrous cycle has the potential to shorten the calving season, increase calf uniformity, and enhance the possibilities for utilizing AI. Artificial insemination allows producers the opportunity to infuse supe...
