Abstract: Histomorphometrical studies were conducted to measure the growth changes in renal corpuscle (RC) and glomerular size in subcapsular, midcortical and juxtamedullary zones of postnatal porcine kidney. The study was carried out in the Department of Veterinary Anatomy, College of Veterinary Science, Rajendranagar on eighteen pairs of fresh kidney specimens collected from slaughter houses in and around Hyderabad. There was a significant increase in RC diameters in all the three zones as age advanced. Larger RCs were seen in the juxtamedullary zone of groups I and II while no significant change was observed in the mean diameters of RC between the three zones of Group III. There was a significant increase in glomerular diameters in all the three zones with age. The mean diameters of the glomeruli were highest in the Juxtamedullary zone in Groups I and II while there was no significant variation in the mean diameter of glomeruli among the three zones in Group III. Number of RCs decreased as age advanced in the Subcapsular and midcortical zones while there was no significant decrease in number of RCs in the juxtamedullary zone. The renal corpuscles were numerous in the subcortical zones of the kidneys.
