abstract
The present study was undertaken to evaluate the biometry of female genitalia of Nellore sheep of Andhra Pradesh. Fifty non-gravid female genitalia of sheep of were collected from the abattoir immediately after slaughter to study the biometry of different parts of genitalia. The biometry was studied in the three groups viz., ewe lambs (n=25), ewes in follicular phase (n=13) and ewes in luteal phase (n=12). Dimensions of less than 10 cm were made by means of vernier caliper and those above 10 cm were recorded with the help of a thread that was calibrated against the measuring scale. The results showed a significant difference (P< 0.01) in different dimension of ovaries, uterine horn, uterine body and cervix between the ewe lambs in comparison with adult ewes; while there was no significant difference (P>0.05) in different dimension of ovaries, uterine horn, uterine body and cervix between adult ewe in follicular and luteal phase of the estrous cycle.
