BIOMETRY OF FEMALE GENITAL ORGANS OF BLACK BENGAL GOAT

Abstract

This study was conducted to establish the normal dimensions of the different segments of the female reproductive tract of the Black Bengal goats from June to December 2009 in the Department of Anatomy and Histology, Chittagong Veterinary and Animal Sciences University, Chittagong. The reproductive tracts of 56 adult non-gravid, female Black Bengal goats were collected, cleaned and freed from adhering tissues and measured. Different segments of the female reproductive tracts of Black Bengal goat, i.e. vulva, vagina, cervix, uterine body, uterine horns, oviducts and ovaries were measured using Metric rule, thread and hand lens. The mean lengths of the vulva, vagina, cervix uterine body, uterine horns and oviduct were 2.658±0.467, 7.132±1.22, 3.280±0.80, 2.548±0.84 and 12.287±2.00 and 10.08±0.697 cm respectively. The lengths of the left and right ovaries were 1.401±0.18 and 1.419±.214 cm, respectively. The diameters of the vagina, cervix, uterine body, uterine horn, left and right ovaries were 3.97±0.730, 1.741±0.30, 2.726±0.586, 2.816±0.52 0.70±0.10 and 0.717±.165 cm c, respectively. The average numbers of follicle in left and right ovaries were 3.892±1.691 and 4.14±1.705 respectively. The average number of curuncle in uterus was 55.767±4.535.The weight of left ovary was 0.5944±0.06 gm and that of right ovary it was 0.614±0.07 gm in Black Bengal goat. There was found a significance difference (p<0.05) between right and left ovaries for ovario-bursal adhesion. The mean weight, length and width in the present study were found higher in right ovaries than those of left ovaries.
