The study was conducted on the heart of 36 morphologically normal goat (Capra hircus) embryos/ fetuses, irrespective of sex. The embryo/fetuses were divided into three groups viz; Group-I (early prenatal period; d†50 days of gestation), Group-II (mid prenatal period; e†51 days and d†100 days of gestation) and Group-III (late prenatal period; e†101 days till parturition) comprising of 12 animals in each. Longitudinal and transverse pieces of different components of heart were collected and fixed in the Zenker’s solution for DNA, Neutral buffered formalin and Bouin’s fluids for PAS and AMPS and cold acetone for lipid, alkaline phosphatase and acid
phosphatase studies. The PAS, AMPS and lipid activity was more in the wall of ventricles in early prenatal period, whereas
