Biometric study on female reproductive tract of Nellore sheep

Abstract

The present biometric study on female reproductive tract of Nellore sheep was carried out at the College of Veterinary Science, Tirupati, using specimens collected from a slaughter house located in Tirupati. It was found that the mean length of ovary, oviduct, uterine horn, uterine body and cervix was 1.05±0.04, 12.78±0.86, 7.70±0.30, 0.73±0.05 and 2.81±0.28 cm, respectively. The mean width/diameter of ovary, oviduct, uterine horn, uterine body and cervix was 0.74±0.05, 0.12±0.01, 0.82±0.04, 1.14±0.05 and 0.89±0.02 cm, respectively. There was no significant difference in measurements between right and left sides in case of ovaries and oviducts. In case of uterine horns, the left one was significantly longer than the right one, while there was no significant difference in terms of diameter. From the results of the present study, it was concluded that the total length of female reproductive tract from tip of ovary to external os of cervix in case of Nellore ewe lambs is around 25.07 cm, and length of left uterine horn is higher than that of right horn.
