Abstract
The present study was conducted on the placentome of 6 gravid uteri of Barbari goat during mid-stage of pregnancy (51 to 100 days) were procured from slaughter house. Each foeti was measured for its crown rump length (CRL) in centimeters with the help of nylon thread. The weight, crown rump length and approximate age of the foeti has been measure. The small pieces of the placentome were collected and processed by routine paraffin embedding technique. The sections were stained with haematoxylin and eosin stain for general histoarchitecture, Wilder's reticular stain for reticular fibres, Masson's trichome stain for collagen fibres and Verhoeff's method for elastic fibers (Luna, 1968). Histologically, the goat placenta exhibited the typical characteristics of cotyledonary type with the discrete area of attachment between maternal and foetal tissue i.e. the placentome. The two components of the placentome were firm attach during mid-pregnancy. Cryptal epithelium occurs in small patches during mid-pregnancy. The cells of the Cryptal epithelium consisting of simple squamous to cuboidal cells with numerous giant cells that increase in subsequent stages. The intercrypt columns comprised of a syncytial mass with some uninucleate and frequently occurring binucleate and multinucleate giant cells. Binucleate cells predominated during mid-stage of pregnancy while multinucleate cells increased as pregnancy advances. Symplasmic bodies frequently occur within the crypts and increase during mid-pregnancy. Cotyledons are subdivided into villus and arcade areas, with villi branching progressively throughout mid gestation.
