These microphthalmic piglets composed of 20 piglets farrowed by three different sows(1, 11 and 8 piglets by No.1, 2 and 3 sow, respectively) that were apparently normal during pregnancy and after parturition. Attempts were made to know epidemiological findings and histopathological changes of these piglets and the results were summarized as follows; 1. One piglet from No. 1 sow exhibited staggering and incoordination and remained alive, but 19 piglets from No. 2 and 3 sow died between 3 and 20 minutes after birth. 2.
