Introduction

  • The aim of pregnancy diagnosis in cattle is to allow accurate determination of the animal’s pregnancy status. This is undertaken as a herd and individual animal management tool and allows appropriate intervention where required to improve reproductive performance and efficiency.
  • The ideal pregnancy test:
    • High sensitivity (correctly identify pregnant animals).
    • High specificity (correctly identify non-pregnant animals).
    • Be inexpensive to perform.
    • Results will be available at the time the test is undertaken.
    • Allow assessment of the viability of the fetus.
    • Allow sex determination of the fetus.
    • Be suitable to undertake under field conditions.
