This study was designed to compare the benefits and costs of two different synchronized artificial insemination programs on two groups of beef first calf heifers. A financial budget was developed that would include cost of synchronized insemination per animal and the added value of a bred heifer compared to an open one.

The two synchronized programs were called controlled internal drug release (CIDR) and Ovsynch. They used a specific timeline and drugs to complete the synchronization process. A single low birth weight high calving ease bull was used for both groups to enforce conformity between the groups. Costs of all inputs, including labor, were budgeted and calculated on a per animal basis. The CIDR program had a higher pregnancy rate than the Ovsynch. Because the test groups were so small there was not enough data to produce legitimate statistical analysis. This process is very time intensive for a beef cattle operation and this may explain why large beef operations do not practice these methods very often.
