STUDY ON GYNAECO-PATHOLOGICAL DISORDERS AND ISOLATION AND IDENTIFICATION OF MICRO-ORGANISMS FROM THE UTERINE DISCHARGES OF COW

Abstract

Cattle are one of the important domesticated animals and easily reared. The local breed of cattle (Bos indicus) can easily survive in our environment but the foreign breed (Bos taurus) rearing needed so much carefully. Now a day the people of Dinajpur Districts rearing crossbreed cattle which are rearing for both meat and milk purposes. The crossbreed animal infertility problem was high so the farmer culling the animal from their herd and which were slaughtered in the slaughter house in Sadar Thana.This is the first study describing the infertility problem in Dinajpur Districts and is aimed to identify the causes of infertility problem and improve fertility to solving the animal protein requirement as per capital needed. During the period of April/2009 to March/2010, a total of three hundred ten (310) female genital tracts were collected from the Dinajpur Sadar Thana slaughter house. During postmortem examination 199(64.19%) genital tracts pathologically disordered and 73(23.55%) pregnant were found. The most common uterine lesion was endrometritis (31.29%) followed by cystic ovary (8.37%), hyperplasia of ovary (6.77%), pyometra (4.84%), parovarian cyst (4.84%), hydrometra (4.52%), hypoplasia of ovary(4.19%), ovarobursal adhesion(3.55%), vaginal cyst(1.29%) and Haemmorage in uterine in horn (0.66%).Histopathological examination was carried out and found destraction of endometrium which is characterized by huge infilteration of reactive cells, destraction of some uterine gland, in pyometra case presence of neotrophil, presence of protenacious mass in oedematous uterus and ovary, in cystic ovary characterized by the cyst wall appeared to be flattened that might have resulted from pressure exerted by the cysts. In bacteriological examination,50 uterine fluid cultured and found that 30% infected by Escherichi coli and 8% infected by Salmonella spp.
