Effects of estradiol and oxytocin injection on the efficiency of artificial insemination in Iranian Zel ewes during the breeding season
In sheep industry, pregnancy rate after artificial insemination (AI) declines due to the complex anatomy of the cervix in ewes, such that it might prevent effective intrauterine insemination. At estrus, cervical relaxation occurs to some degree in ewes, which is regulated by the changes in the levels of reproductive hormones. This study aimed to evaluate the effects of estradiol and intravenous...
متن کاملOpportunities For Improving Reproductive Management And Efficiency Of The Swine Breeding Herd With Artificial Insemination
Current Status of AI Use The USA swine breeding herd has been reported to include 3.9 million sows. Approximately 60% of these sows were determined to have been mated by artificial insemination. Each sow received 6.5 doses of semen annually, for a total of 25 million doses utilized in a single year (1999, Boar Semen Conference).
