Abstract

This study was undertaken to investigate congenital microphthalmia occurred at a pig farm in Gyeongbug province. 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. In histopathological finding, hypoplasia and edema of all organs were observed in all piglets, and significant of lesions related to infection of microrganisms were not observed. 3. The cause of microphthalmia was considered as hypovitaminosis A in the sown intaked only barley barn before and during early pregnancy.
