Abstract:
The present study was conducted on the kidneys of six each of adult broiler chicken and broiler ducks. Histologically, the kidneys of all studied birds consisted of two zones, the cortex and medulla. In both species, the cortex made up majority of the area of the kidney. Three types of nephrons were noticed in the cortex of chicken viz. small reptilian type nephrons towards the surface of cortex, large mammalian type nephrons near the medulla and intermediate type nephrons in the deeper parts of cortex while in duck the first two types only were seen. Proximal and distal convoluted tubules were present within the cortex. In the case of duck, cortex presented numerous small cortical nephrons and only a few large mammalian type nephrons. These results revealed that histologically the renal cortex in broiler chicken and broiler duck showed difference in the pattern of arrangement and in the size of various components.
