Histochemical studies on cerebral and cerebellar cortices of pig (Sus scrofa)

Abstract

The histochemical aspects of cerebral and cerebellar cortices were studied in Large White Yorkshire cross-bred pigs at different age groups. The neuronal cells and neuropil of cerebral neocortex, the neuropil and Purkinje cell layer of cerebellar cortex showed positive for PAS, Alkaline phosphatase and Acid phosphatase activities in all age groups of pigs. However the PAS, Alkaline phosphatase and Acid phosphatase activity was stronger in finisher age group. Negative Alkaline phosphatase activity was observed in the cerebral and cerebellar cortices of preweaner age group. The amount of fat deposition in cerebral and cerebellar cortices was more in the finisher age group when compared to preweaner pigs.
