| Abstract | ||
| The study examined growth and morphological alterations of the kidneys in Awassi sheep at two critical developmental stages; pre-birth (3–4 months of gestation) and post-birth (3–4 months after birth). The findings indicated that the kidneys of embryos gestating for 3 -4 months were diminutive and slender, encased in a removable fibrous capsule. The brains were pale, and the renal pyramids were just beginning to take shape. It is typical for the right kidney to be higher than the left. The right and left kidneys were about the same dimensions (length, width, thickness, and weight) at this point. But when they were born, the kidneys of lambs increased a lot in all morphometric metrics, making them look like beans since they got bigger, thicker, and smoother. The fibrous capsule was more securely attached to the renal parenchyma, and the cortex and medulla were clearly different from each other. The renal pyramids were well-formed, and the renal pelvis was easy to see, which meant that the kidney was getting bigger. The data suggest that the growth of sheep's kidneys remains proportionate bilaterally, with significant alterations occurring pre- and postnatally due to inherent growth processes. This study provides valuable insights into the morphology and dimensions of the kidneys in Awassi sheep during their growth. It can be used as a reference for research that looks at the anatomy of different animals, how they grow, or birth problems in tiny ruminants. | ||
