Abstract:
A total number of eighteen sheep foetuses were divided into three groups viz. early gestational age (1-50 days), mid gestational age (51-100 days) and late gestational age (101-till birth) with six foetuses in each age group. The spleen of sheep was first observed at 50 days of gestation in the present study. The spleen appeared reddish brown in color and acquired the shape of oyster shell at 56 days of gestation. The surfaces of the spleen were clearly demarcated at 56 days of gestation. The borders were thin and anterior border of spleen was positioned at 10^th rib whereas the posterior border was extended beyond 13^th rib at 93 days of gestation. The biometric parameters such as length, width and weight of the spleen was progressively increased with the age advanced in all prenatal age groups.
