520.3.#.a: We investigated the effect of epidural versus intramuscular administration of alarelin acetate (gnrha; 25 μg) at artificial insemination (ai; day 0) and/or 7 days after ai on the pregnancy rate (pr) of holstein cows that exhibited estrus spontaneously after their voluntary wait period. cows (n = 117) were randomly allocated to treatment and control groups. in groups im0, im7, and im07 (n = 12 per group), cows received gnrha intramuscularly (im) at 0 or 7 days, or both, respectively. in groups ep0 (n = 19), ep7 (n = 13) and ep07 (n = 11), cows received gnrha at the sacrococcygeal epidural site (ep) at 0 or 7 days, or both, respectively. animals in the control group (con) received 5 ml of normal saline at 0 and 7 days. pregnancy diagnosis was performed by rectal palpation of the uterine horns 60 days post ai. results showed a significant difference in pr/first ai between im0 and ep7 groups (16.67% vs. 61.54%; p < 0.05). moreover, the results showed no significant differences in overall pr after two rounds of inseminations among all groups 60 days after the second ai. in conclusion, epidural injection of gnrha 7 days after ai versus its intramuscular injection at ai improved pr/first ai significantly in holstein lactating cows.
