Abstract/ Executive Summary:

The anatomical studies of the kidneys of Rhode Island Red (RIR) and White Leghorn (VvlH) chicken during their postnatal stages of growth and development were investigated in the present study. The chicken were grouped into day old, day 30, day 90, day 180 and day 360.The gross structures of the kidney (weight, relative weight, length, breadth and thickness) during their growth period were estimated by using the measuring balance and scale. The histological structures of the kidney (the nephrons, the number of glumerulae and the presence of collagen and elastic fibers within the kidney) were also studied by light microscope using hematoxylin and eosin stain, Van Gieson and Verhoeffs stain. The gross structures were significantly higher in the RIR than the WLH chicken whereas the histological structure (number of glomerulae) were higher in WLH than RIR chicken. From these data it may be suggested that these differences did not depend on the developmental stages of growth and development but depend on the genetic variation of the chicken.

Program Area: Animal Health and Management

Commodity: Chicken

Objectives:

To clarify the anatomy of the kidney of RIR and WLH chicken during their postnatal stages of growth and development.

Methodology:

In order to study the normal anatomy of the kidney's of RIR and WLH chicken at different ages, a total of 30 chicken from these two genetic breeds (15 from each breed) were subdivided into five age groups, viz. day old, day 30, day 90, day 180, and day 360 chicken (each group provided with six chickens) were investigated at the department of Anatomy and Histology, Bangladesh Agricultural University, Mymensingh. The chickens used in this research were collected from the poultry farm of Bangladesh Agricultural University. Body weight of each bird was recorded just prior to slaughter. The weight, relative weight, length, breadth and thickness of the kidney were recorded immediately after obtaining the kidneys from the healthy chickens. The relative weight of the kidneys were calculated as follows: Relative weight of the kidney = weight of the kidney! body weight. The aseptic measure was taken during collection and processing of the samples for avoiding unusual contamination. The tissues from the kidneys were fixed in Bouins solution. All the tissues were dehydrated with a series of graded alcohol and routinely embedded in paraffin wax. The tissues were sectioned at 6 micrometer. Three stains were used; 1. Mayer's hematoxylin and eosin for general histological studies, 2. Weigerts elastica Van Gieson for collagen fibers and 3. Weigert Verhoeff's stain for elastic fibers. All the tissues were observed with a light microscope and the photographs were taken for sampling the histological feature of the kidney.

Achievement/Findings:

From the present research findings it may be concluded that the gross anatomical parameters of the kidney were higher in RIR than WLH chicken whereas the histological parameters of the kidney (number of glomerulae) were higher in WLH chicken than RIR chicken. These difference did not depend on the developmental stages but depend on the genetic variation of the chicken.
