“…The use of freshly diluted semen could give the best result: 70 to 82 % (Donovan et al, 2001 and and 82.2% (Hill et al, 1998;Ehling et al, 2003). A similar level could be reached with cooled and stored semen /74-76% (Gergátz&Gyökér, 1997) and 56.7% (Fernandez-Abella et al, 2003) as well as with chilled and stored semen /between 37.5% (Fernandez-Abella et al, 2003) and 64.2-73.33% (Stefanov et al, 2006)/.…”

“…About 50 to 100 million spermatozoa is needed in one dose to vaginal insemination, but 25 to 50 million are suggested for cervical insemination and 15 to 20 million is enough for laparoscopic AI (Kukovics, 1974;Jávor et al, 2006;Gergátz, 2007). However, several scientists have used much higher numbers: 106 (Fernandez-Abella et al, 2003), 50 to 300 (Ehling et al, 2003) and 400 (King et al, 2004) million spermatozoa in one dose of semen.…”

“…roscopic AI with fresh semen enables sperm number to be reduced to <50 million sperm per dose (Ehling et al, 2003), which limits the number of doses per ejaculate to <100 ewes to achieve pregnancy rates >70% (Sayre and Lewis, 1997). This coupled with the seasonality of sheep production requires a large number of rams to enter AI to facilitate a genetic improvement program.…”

“…It also provides a controlled semen placement, but irritations of the endometrium by manipulating the endoscope in the uterus or by the use of a pneumouterus in a non-surgical deep intrauterine insemination procedure are minimised. Laparoscopic intrauterine insemination is successfully used in sheep for different purposes (Gourley and Riese 1990;Moses et al 1997;Ehling et al 2003;PereyraBonnet et al 2011). In pigs such a method has been used only to a limited extent so far (Fantinati et al 2005;Brüssow et al 2006Brüssow et al , 2011.…”
