%X In the present study the effects of lecirelin acetate injections applied in different ways after artificial insemination on the pregnancy rate of cows were investigated. As a material, 180 cows showing the spontaneous oestrus between 50-120 days after parturation and having the sexual cycle at regular intervals and showing no clinical disorders during the treatment process were used. The cows were randomly divided into 4 groups as A, B, C and D. In the group A (n = 50) 50 ¦Ìg lecirelin acetate was injected to the sacrococcygeal epidural space of the animals immediately after the artificial insemination . The animals in the group B (n = 40) were injected with 2 ml physiological saline solution by the same route applied to the animals in the group A. The animals in the group C (n = 50) were injected with 50 ¦Ìg lecirelin acetate intramuscularly immediately after the artificial insemination. The animals in the group D (n = 40) were injected with 2 ml physiological saline solution by the same route applied to the animals in the group C. Statistically significant in difference (P <0.05) were observed between the pregnancy rates of groups A and B (64%) and (45%). It was detected that there was no significant difference (P>0.05) in the pregnancy rates of the groups C and D (60% and 52,5%, respectively). In addition, no significant difference (P>0.05) was observed between the group A (applied epidural GnRH) and C (applied intramuscular GnRH). As a result, it was concluded that either intramuscular or epidural administration of Lecirelin Acetate to cows showing spontaneous oestrus can be used after artificial insemination to increase the pregnancy rates
