Comparative Histomorphochemical Studies on Uropygial Gland of Kadaknath and White Leghorn Breeds of Poultry

Abstract

The present study was conducted on ten each uropygial glands of 6 to 8 months old healthy Kadaknath and White Leghorn breeds of poultry. The tissue samples were stained by H and E for normal histological structures, Verhoeff’s stain for collagen and elastic fibers, PAS (Periodic Acid Schiff’s) for glycogen and Alcian Blue PAS method for acid mucopolysaccharides. The uropygial gland in Kadaknath and White Leghorn was composed of two lobes. Each lobe had a single duct and these ducts were joined together by isthmus. The thickness of capsule was more in White Leghorn than Kadaknath breed. The lumen of tubules showed higher concentration of secretary product in Kadaknath breed. Numbers of tubules were higher in Kadaknath. No aggregation of lymphocytes was found in the preen gland of White Leghorn, whereas in Kadaknath, there was large number of lymphocytes aggregation alongwith lymphatic nodules. Melanin pigmentation was the characteristic feature of Kadaknath which was found towards the central cavity and in between ductules. The capsule of White Leghorn showed intense PAS activity, while moderate activity was found in Kadaknath breed of poultry. Intense ACPase reaction was noticed in capsule of uropygial gland of Kadaknath and White Leghorn breeds of poultry.

​​Comparative Micro and Macro Anatomical Observation on Preen Gland of Kamrupa (Gallus domesticus), White Leg Horn (Gallus domesticus) and Daothigir Fowl (Gallus domesticus) of Assam

“…The thickness of capsule of preen gland was more in Daothigir ( The preen gland of Kamrupa, W hite leg horn and Daothigir was bounded by connective tissue capsule. These findings concurred with the findings of Kanasiya et al, (2017) in Kadaknath and W hite Leghorn breeds of poultry and Ushakumary et al, (2011) in Guinea fowl. The thickness of capsule of preen gland of Daothigir, W hite leg horn and Kamrupa were 40.32±1.61µm, 38.41±2.31 µm and 36.51±µm, respectively.…”
