TOPOGRAPHIC RELATIONS OF PANCREAS DURING DEVELOPMENT IN KUTTANAD DUCKS (Anas platyrhynchos domesticus)

Abstract

A study was conducted to trace the topographic relations of pancreas during prehatch and posthatch periods in Kuttanad ducks using 18 embryos and 78 female ducklings from the day of hatch to 24th week of age. Though the primordium appeared on third day of incubation, the gland attained a visible size on 10th day. The gland was located in the duodenal loop and did not show impressions of any visceral organs during embryonic life. However, on the day of hatch itself, the ventral lobe showed impressions of both limbs of duodenum. Impressions of various visceral organs viz., gizzard and left caecum appeared on the surfaces of dorsal and ventral lobes only by second week of posthatch period. Generally, as the age advanced, the impressions of these visceral organs on pancreas became more extensive and prominent
