Donovan, A., Hanrahan, J. P., Kummen, E., Duffy, P. & Boland, M. P. Fertility in the Ewe following cervical insemination with fresh or frozen-thawed semen at a natural or synchronised oestrus. Anim.
The study aimed to determine the pregnancy rates of indigenous field sheep following different approaches to trans-cervical artificial insemination (TCAI). TCAI was performed in oestrus induced ...
Introduction Cervical artificial insemination (AI) with frozen-thawed semen in sheep has yielded unacceptably low pregnancy rates. The exception is in Norway where vaginal AI yields non-return rates in excess of 60%, ...
