Title : Cerebellar hypoplasia and hydrocephalus in lambs
Authors : E. ORU
Summary : Cerebellar hypoplasia and hydrocephalus were investigated in a total of 11700 births whose 472 abortion / stillbirth cases from 26 sheep flocks during 2 lambing seasons. These brain anomalies were only diagnosed in 6 flocks mainly performing extensive breeding. The prevalences of cerebellar hypoplasia and hydrocephalus in abortion/stillbirth cases were 2.33% and 1.69% respectively and were relative high for congenital defects. Three histological (microscopic, intermediate and severe) types of cerebellar hypoplasia were identified, the most frequently observed being the intermediate type (56.25% of hypoplasia cases). Three microscopic and 2 intermediate types were encountered also in alive lambs as well as one case of hydrocephalus. These results suggest that the 2 brain anomalies were probably linked to inherited disorders coupled to some toxic and infectious causes.
