During phase II pregnancy diagnosis was found to be 100 percent accurate by ultrasonography and 55.55 percent accurate by abdominal palpation. The litter size estimation was 90.74 percent and 23.80 percent accurate by ultrasound examination and abdominal palpation, respectively during this phase. Pregnancy diagnosis by ultrasonography was found to be 100 percent accurate, abdominal palpation was 61.11 percent accurate and radiography was 94.44 percent accurate during phase III.
