Abstract

Gross anatomical features of develop- ing rumen was studied in 36 goat foeti of both sex. The primordia of the ru- men was noticed on 38 day of gestation between 11th to 13th rib. Rumen was displaced from 8th rib to 1st lum- bar vertebrae on 134 day onwards. It was roughly quadrilateral shaped through- out the gestation. The dorsal sac of rumen grew faster than the ventral sac. The cranial and caudal transverse grooves and right and left longitudinal grooves were observed at 46 days and coronary grooves were observed at 50 days of gestation. Well distinguished cranial and caudal pillars were observed on 46 days of gestation. Well developed right and left longitudinal folds were demarcated on 55 and 100 days, respectively. Biometrical parameters viz. length, height, width and diameter increased as age advanced.
