Factors affecting the conception rate of ewes inseminated with frozen semen



Factors affecting the conception rate of ewes inseminated with frozen semen



Ovtsevodstvo (5): 39-40



Precoce ewes were inseminated with 0.2 ml thawed semen containing 90X106 to 100X106 motile spermatozoa using different methods as follows: (1) deep cervical deposition of semen using a vaginal speculum (37 females ); (2) as 1 plus application of 0.2 ml 1% cocaine solution to the cervix prior to AI (10 females ); (3) as 1 plus elevation of the ewe's rump by 80 cm during AI (21 females ); (4) as 1 plus stimulation of the cervix by an electric current of 3.7 volts during AI (5 females ); (5) deep cervical deposition of semen without using a vaginal speculum (64 females ). For the 5 groups resp., the CR was 40, 31, 29, 18 and 50%.
