Bu çalışmada, ineklere
suni tohumlama sonrası farklı yollardan lesirelin asetat enjeksiyonlarının
gebelik oranları üzerindeki etkisi araştırıldı. Materyal olarak postpartum
50-120. günler arasında kendiliğinden östrüse gelen, düzenli aralıklarla
seksüel siklus gösteren ve bu süreçte herhangi bir klinik bozukluk göstermeyen
farklı ırk ve yaştan 180 inek kullanıldı. Çalışmada kullanılan inekler rastgele
4 gruba ayrıldı. A grubunda bulunan (n= 50) hayvanlara suni tohumlamadan hemen
sonra 50 µg lesirelin asetat, B grubu (n=40), hayvanlara 2 ml serum fizyolojik üst
epidural boşluğa uygulandı. C grubu (n=50), hayvanlara suni tohumlamadan hemen
sonra kas içi 50 µg lesirelin asetat, D grubuna (n=40), 2 ml serum fizyolojik gene
kas içi olarak enjekte edildi. Lesirelin asetatın üst epidural boşluğa
uygulandığı A ve B grubunda hayvanların gebelik oranları (sırasıyla % 64, % 45)
arasında farklılığın istatistiki açıdan anlamlı olduğu (P<0.05) görüldü. Kas
içi uygulama yapılan C ve D grubunda gebelik oranları (sırasıyla % 60, % 52,5)
yönüyle arasındaki farkın anlamlı olmadığı (P>0.05) belirlendi. Ayrıca, üst epidural
ve kas içi GnRH uygulanan gruplar arasında da istatistiki bir farkın (P>0.05)
olmadığı tespit edildi. Sonuç olarak, yapılan
çalışmada kendiliğinden östrüse gelen ineklere tohumlama ile birlikte epidural
yolla uygulanan GnRH enjeksiyonlarının gebelik oranlarını artırmada faydalı
olacağı kanaatine varıldı.

Effect on Pregnancy Rates of Injected Lecirelin Acetate (GnRH analogue) after Insemination in the Cows

Öz

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 µg 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 µg 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.
