Morphometrical study of cervix in Lori sheep

The lambing rate after transcervical insemination in sheep is low mainly due to complexityof cervical canal. There are many anatomical and morphological differences in cervicalstructure between different breads of sheep. The aim of the present study was to investigate the anatomical characteristics of cervical structures in Lori sheep. For conducting of this research, 44 female genital systems of healthy Lori sheep (10 ewe lambs and 34 adult ewes) from Khorramabad slaughterhouse were selected and transfered to lab. After performing of cervix biometry, injection of silicone was done in order to prepare the cervix mould. In this study biometrical results in adult sheep were include: The mean length, weight, diameter and number of cervical folds of cervix were 59.90mm, 11.73g, 15.07mm and 5.73, respectively. Silicone moulds of cervix reveal the shape, position and size of mucosal folds in cervical canal.
