| Understanding normal fetal growth rates of the vertebral column, and between species, provide a basis to establish reference values for evaluation of body development and estimation of fetal age by ultrasonography. Goats are also widely used in biomedical perinatal research and are still considered a key to understanding the skeletal development. This study was carried out to clarify growth of length of vertebral column at segmental, regional, and total level of vertebral column in the fetal goats during different gestational age. The length of each vertebral segment of 25 goat fetuses, aged between 6 and 20 weeks were measured for each vertebra using a digital caliper. Our study demonstrated differences among various fetal ages in terms of regional,... |

| The study has been conducted on the prenatal development of testis on 70 goat embryo/foeti, categorized into group-I (0-30 days), Group-II (31-60 days), Group-III (61-90 days), Group-IV (91-120 days) and group V (121days-till birth), having 14 embryos/ foeti in each group. The genital ridge was observed at 23 days of gestation. It contained an accumulation of mesenchymal cells, immature RBC's, differentiating fibroblasts and primordial germ cells. The formation of sex cords was evidenced on 44th day of gestation. It contained small mesenchymal cells and large cells arranged in a chain like manner. The convolution of the sex cords started between 61-90 days of gestation, which increased with the increase in the gestation period and at 125 day of gestation... |
