Biometry of Genitalia, Incidence of Gynecological Disorders and Pregnancy Loss in Black Bengal Goat : An Abattoir Study

Abstract

This study was aimed to determine the biometry of genital organs, incidence of gynecological disorders and pregnancy loss in Black Bengal goat (Capra hircus). Genitalia of 118 does were collected from local abattoirs. Biometric parameters of genital organs were measured and gross and histopathological examinations were carried out for detection of abnormalities. For gravid uterus, age of the fetus was determined by measuring crown-rump length. There was no significant difference in the length, width and weight of right and left ovaries (P>0.05). However, the number of follicles between left (5.3 ± 2.3) and right ovaries (7.4 ± 2.7) varied significantly (P<0.05). The mean length of right fallopian tube and uterine horn were not varied with those of left fallopian tube and uterine horn. The length of uterine body, cervix and vagina were 1.3 ± 0.1 cm, 3.3 ± 0.5 cm and 6.8 ± 1.3 cm, respectively. Overall, 29 (24.6%) genitalia had abnormalities. Fifteen genitalia (12.7%) had ovarian abnormalities including ovaro-bursal adhesions (6.8%), parovarian cyst (5.1%) and follicular cyst (0.9%). Uterine abnormalities were found in 12 genitalia (10.2%) and predominant uterine lesion was endometritis (6.8%) followed by adenomyosis (1.7%), hemorrhagic lesion on endometrial surface (0.9%) and cyst in broad ligament (0.9%). In addition, cyst in fallopian tube (0.9%) and vagina (0.9%) were recorded. The proportion of slaughtered pregnant goats was 15.3% (18/118). The pregnancy wastage was highest in the first month (50.0%) followed by second (33.3%) and third (16.7%) month. It can be concluded that ovaro-bursal adhesions, parovarian cyst and endometritis are the gynecological disorders of major concern in Black Bengal goat.

Proceeding

“…Out of the 200 samples, 49 samples were found to be infected with a prevalence of 24.50%. The present observation is compatible with that of Talukder et al (2015) in Bangladesh and Beena et al (2016) in UP, India. A total of 15 (7.5%) were found to be pregnant.…”

Conceptus-related measurements at early pregnancy in Black Bengal goat: an abattoir study

“…In the laboratory, genitalia were cleaned and freed from adjacent tissues and kept on the dissection table in normal position. The biometric parameters (length and diameter) of uteri were determined using measuring scale and slide calipers according to a previously described protocol (Talukder et al, 2015). The uteri were carefully dissected and conceptus enclosed in chorio-allantoic sac was taken out and kept in a tray.…”

Study of Incidence of Gross Urogenital Lesions and Abnormalities on Does Slaughtered at Nyagatare Slaughterhouse, Eastern Province, Rwanda

“…There are a number of studies on the prevalence of several abnormalities of the female reproductive tract of sheep [ 9 , 10 ] and goats [ 11 – 14 ]. Most of the reports on female reproductive abnormalities emanate from the Middle East [ 10 , 11 , 15 – 18 ], the Indian subcontinent [ 13 , 14 , 19 , 20 ], and sub-Saharan Africa [ 12 , 20 , 21 ].…”

“…The prevalence of female reproductive abnormalities in different breeds of sheep reportedly vary from 0.72% to as much as 52.7% [ 10 , 15 , 18 ] whilst that in goats vary from 8.08% to 38% [ 11 , 18 , 19 , 22 – 24 ]. Female reproductive tract pathology predominantly affects the uterus, followed by the ovary, the cervix, fallopian tubes, and vagina in that order [ 2 , 6 ] mainly due to parasites such as trypanosomes [ 25 , 26 ] and environmental pollutants such as arsenic [ 27 ] and neoplasia [ 6 , 17 ].…”
