The thyroid glands were clearly visible, enlarged, and palpable in all the dead kids. The fetuses had a large swelling in the cranio-ventral neck region. Upon cutting skin in each fetus, the swelling revealed the extremely enlarged thyroid gland with two almost symmetrical lobes with both lobes approximately 15 × 8 × 5 cm in size.Histopathological hyperplastic goiter was observed in four kids and colloid goiter was diagnosed in three.Twins or triplets were observed to be predisposed to congenital goitre. All the stillborn kids were twins or triplets. On the other hand, single-born kids survived and showed a normal growth rate.
