Gynaecopathological disorders of female reproductive systems of cows suspected for their culling at Birgonj of Dinajpur district

Abstract

This is the first study describing the infertility problem in Birgonj Upazila and is aimed to identify the causes of infertility problem and improve fertility to solve the deficiency of animal protein requirement as per capital needed. During the period of January to December/2011, a total of two hundred fifty eight (258) female genital tracts were collected from the slaughtered animal of different bazer under Birgonj Upazila and from the slaughter house of Birgonj municipality. Gynaecopathological disorder is a common problem of heifers and cows in Bangladesh. The most common gynaecopathological disorders are endometritis, pyometra, mucometra, cervicitis,gravid uterus,haemorrhage in ~ uterine horn, vaginitis, vulvitis, cystic ovary, par ovarian cyst,ovaro-bursal adhesion,haemorrhage in the ovary, atrophied ovary, hyperplasia of the ovary,hydrosalpinx mummified foetus and _ salpingitis.During postmortem examination 166 (65.11%) genital tracts pathologically disordered. The most common pathological lesions were atrophy of the ovary (21.31%), followed by cystic ovary (12.01%), hyperplasia of ovary (2.32%), par ovarian cyst (1.16%), ovaro bursal adhesion (1.16%), haemorrhage in ovary (1.55%), -endometritis (6.97%), pyometra (5.03%), mucometra (1.16%), cervicitis (6.58%), gravid uterus (4.26%) and haemorrhagic lesion in uterine horn (1.55%). Histopathological examination was carried out and found destruction of endometrium which is characterized by huge infiltration of reactive cells, destruction of some uterine gland. In case of pyometra presence of neutrophils, presence of proteinacious mass in edematous uterus. The cystic ovary characterized by the cystic wall appeared to be flattened that might have resulted from pressure exerted by the cysts. Cattle are one of the important domesticated animals and easily reared. The local breed (Bos indicus) can easily survive ion our environment but the foreign breed (Bos taurus) rearing needed so much carefully. Now a day the people of Birgonj Upazila reared crossbreed cattle which are rearing for both meat and milk purposes. The infertility problems of crossbreed animal was high so the farmer culling the animal from their herd which were slaughtered in the slaughter house in Birgonj . municipality and different hat and bazer of Upazila.
