Abstract

Reduction of the number of days open is economically desirable for the dairy producer. A test is currently being marketed which claims to accurately detect the open cow at 3-7 days post breeding via the detection of a unique protein detected in the serum of the pregnant cow. Evaluation of this test revealed a sensitivity of .51 and a specificity of .55. These results indicate that the test, as performed in this study, did not accurately assess the open status of dairy cattle.
