| dc.description | Bangladesh is an agricultural based country. Most of the people in this country
depend on agriculture. Livestock is an integral part of agriculture and cattle help
to provide important source of animal protein. In our country there are
two types of cattle reared; Bos indicus and Bos taurus. Now a day we found
that some people reared crossbred cows which are used for milk and meat
purposes. The 100% foreign breed animal cannot survive in our environment
easily. The local breed can easily survive in our environment but production
performances not as high as in foreign breed. So recent trend is to choose the
crossbred cattle rearing. Sometimes it was reported that the cross breed, local
breed and foreign breed are infertile due to defective breeding programmed,
inadequate knowledge of rearing system and their ration formulation. Inadequate
nutrition was the major cause of the ovarian atrophy and subsequent estrus
(Kumi-Diaka, 1981) and some bacterial infection. Gynaeco-pathological disorder
is most common which was characterized by the incidence of smooth ovaries
among crossbred cows and appeared lower in local cows (Hussain ef a/., 1987;
Farooq et al., 2000). | en_US |
| dc.description.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. | en_US |
