MICROMETRICAL STUDIES ON THE SEQUENTIAL GROWTH OF THE PRENATAL LIVER OF GOAT (CAPRA HIRCUS)

Abstract

The present study was conducted on the liver of goat foeti at various prenatal ages viz Group I (below 50 days), Group II (between 50-100 days) and Group III (above 100 days) containing 6 number of foeti in each group to study the growth of the same organ in terms of its micrometrical attributes. The mean values for thickness of capsule and diameter of central vein in right, left, caudate and quadrate lobes differed significantly (p<0.05) between groups II and group III. Again, the mean values for nuclear diameter of hepatocytes in right and left lobe differed significantly (p<0.05) between all the age groups. Caudate and quadrate lobes could not be detected in the animals of age group I. However, nuclear diameter of hepatocytes in these lobes did not differ significantly between groups II and III. The mean values for number of hepatocytes per field in left lobes differed significantly (p<0.05) between groups I and II. The number of hepatocytes per field in respect of right lobes did not differ significantly in all the age groups.
