Simple Pregnancy Testing

• Simple pregnancy testing (DRGTTEST.net) The standard management procedure is to make a pregnancy test four weeks after mating in order to establish whether a sow is pregnant or not. This can be modelled in a Bayesian Network (BN).
• Enhanced pregnancy testing ( DRGTTST1.net) A more realistic example includes the heat detection at three weeks after mating, and allows for the possibility of different herd levels for the pregnancy rate.
