Studies on laparoscopic intrauterine insemination of barki ewes (using different insemination doses)‎ as compared with cervical insemination

Abstract EN

The present study aimed to investigate the efficacy of laparoscopic intrauterine insemination as compared with cervical insemination in Barki ewes as well as to set the optimum number of spermatozoa per laparoscopic insemination.

A total of 33 oestrus-synchronized Barki ewes were divided into four groups, the first three groups were inseminated laparoscopically with either 10 x 107 (group 1), 20 x 107 (group 2) or 40 x 107 sperm/dose (group 3).

The 4th group was cervically inseminated.

The results showed that lambing rate after laparoscopic intrauterine insemination using 20 x 107 spermatozoa (75.00%) was superior to either laparoscopic insemination using 10 or 40 x 107 spermatozoa or cervical insemination using 80 x 107 spermatozoa (37.50%, 62.50 and 55.56%, respectively).

Conclusively, intrauterine insemination using the technique of laparoscopy is a relatively simple, field applicable and convenient mean of achieving high lambing rates.

Furthermore, 20×107 motile spermatozoa is the recommended laparoscopic insemination dose in Barki ewes.
