SÜTÇÜ İNEKLERDE GONADOTROPİN SALGILAYICI HORMON (GnRH) ENJEKSİYONU İLE GEBELİK ORANLARININ YÜKSELTİLMESİ ÜZERİNDE ÇALIŞMA

Year 1986, Volume: 2 Issue: 1, 27 - 35, 01.03.1986

Abstract

Bu çalışmada, sütçü ineklerde aşım sırasında uygulanan Gonadotropin
Salgılayıcı Hormon (GnRH) 'un gebe kalma oranı üzerindeki
etkileri araştırıldı.
Materyal olarak 69 adet inek kullanıldı. Deney hayvanları iki guruba
ayrılarak 33 ineklik birinci guruba aşımdan hemen sonra 25 ug
Gonadorelin (Factrel) ikinci guruba ise 0.5 ml Placebo enjekte
edildi. Aşıını izleyen 19- 21. günlerde östrüs ve 60. günde de gebelik kontrolları
rektal muayene ile yapıldı.
Factrel enjekte edilen ineklerdeki gebelik oranı (% 81.81), kontrol
gurubuna kıyasla (%63.88) daha yüksek olarak saptandı.
Deneme guruplarının yaşlara göre değerlendirilmesinde, 5 yaşın üzerindeki
hayvanlarda gebelik oranı farkı daha yüksek olarak ortaya
çıktı.
Doğum ile aşım arasındaki sürenin etkisi ise postpartum 60. güne
kadar ve 60. günden sonra olmak üzere 2 gurupta incelendi ve 60. güne
kadarki tedavi ve kontrol gurupları arasındaki gebelik farkı, 60. günden
sonrakilere kıyasla daha yüksek bulundu.
Sonuç olarak, postpartum erken dönemde tohumlanan ineklerde
GnRH uygulamaları ile gebelik oranlarının arttırılabileceği kanısına varıldı.

Improvement of pregnancy rates in dairy cows with GnRH injections

Year 1986, Volume: 2 Issue: 1, 27 - 35, 01.03.1986

Abstract

In this trial, the efficacy of Gonadotropin Releasing
Hormone (FactrelR), administrated at the time of mating, on the pregnancy
rate of dairy cows were studied.
Sixty- nine cows were used as materials. Animals were divided in to
two· groups and 25ug Factrel were injected to the first group of 33 animals and Placebo to the second group of 36 animals.
Rectal exploration was performed. for estrous controls and pregnancy
examinations were done post- mating 19- 21 and 60 days respectively.
The pregnancy rates of Factrel injected group (81.81 %) were
found higher than the controls (63.88%). The value was found significantly
higher between the two groups (P :<; 0.01).
The results were evaluated among the age groups. The differences
in the pregnancy rate were found higher in younger cows ( <; 5 ages).
There was a marked improvement in the fertility rate in hormone
treated cows after the relatively short interval ( <;; 60 days) between
calving and mating.
As a conclusion, the pregnancy rates could be improved with GnRH
injections at the time of mating in the early postpartum cows.
