Reproductive efficiency of dairy cattle causes great frustration and potential lost income for dairy producers. Even under optimal conditions, the reproductive process is less than perfect because of multiple factors involved in producing a live calf.
In order to extend the genetics of superior dairy cows beyond the two or three calves a typical cow will produce, several reproduction technologies have been developed to increase the number of calves...
