POSTNATAL DEVELOPMENT OF LIVER OF COBB 500 BROILER STRAIN UNDER SMALL SCALE FARMING CONDITION

Abstract

The objective of this study was to investigate the postnatal development of liver in “Cob-500” broilers from day 1 to day 32. Four groups of Cob-500 broilers were taken at day 1, day 14, day 28 and day 32. Five apparently healthy broilers were taken in each group. They were killed in halal method, dissected in systemic way and liver were collected. Then their shape, size, weight of liver and diameter of hepatic lobule, number of hepatic lobule were recorded. Samples from different segments were prepared and stained with haematoxylin and eosin staining technique to study the histology under light microscope. The average length (mm), weight (gm) of liver and diameter (µm) of hepatic lobule, number of hepatic lobule were significantly higher in Cobb 500 at day 35than that at day28, day 14, and day 1.
