Effect of side of insemination on transuterine transport of spermatozoa in superovulated dairy cattle

Eleven superovulating Friesian lactating cows were inseminated deep into one uterine horn with one unit of frozen semen, containing 2.5 million total spermatozoa, with more than 40% postthaw progressive motility and with 14% morphologically abnormal spermatozoa. Semen was deposited into the right or...

Zusammenfassung:Eleven superovulating Friesian lactating cows were inseminated deep into one uterine horn with one unit of frozen semen, containing 2.5 million total spermatozoa, with more than 40% postthaw progressive motility and with 14% morphologically abnormal spermatozoa. Semen was deposited into the right or left uterine horns of alternate cows. There was no difference in the proportions of fertilized recovered ova from ipsilateral horns between right and left inseminations (P>0.05). The fertilization rate in the contralateral horns was higher (P
