The Use of Linear Array Real-Time Ultrasonography for Pregnancy Diagnosis in Pigs,ich will not be followed by therapeutic measures such as induction of oestrus, is only of economic interest when farrowing rate are lower than 80%; it may, however, lead to a reduction in net return (returns minus costs, labour included) at higher farrowing rates. So both the accuracy of pregnancy d
