⚡ TL;DR(Too Long; Didn't Read)

Findings suggest that; i) for the P4 concentrations, there was no marked difference between implant-treated and control groups, as remaining below 1 ng/ml all, and ii) short-acting deslorelin implant could not induce fertile oestrus cycles in coloured Mohair goats during the suckling (anoestrous) season.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:It is known that the pituitary FSH and LH stores are dramatically depleted during the anoestrous in seasonal breeders.
📊
Key Findings & Data:Suckling goats (n=21) of coloured Mohair breed were randomly assigned into two trial groups: Goats in Group I (n=11, Ovuplant®) received subcutaneously the implant (2.1 mg deslorelin), while animals in Group II (n=10, control) received no treatment.

Abstract

It is known that the pituitary FSH and LH stores are dramatically depleted during the anoestrous in seasonal breeders. Hence, the aim of this study was to evaluate the effect of deslorelin implant (a GnRH analogue) to induce oestrus in suckling goats. Suckling goats (n=21) of coloured Mohair breed were randomly assigned into two trial groups: Goats in Group I (n=11, Ovuplant®) received subcutaneously the implant (2.1 mg deslorelin), while animals in Group II (n=10, control) received no treatment. Along with the implant administration, serum progesterone (P4) concentrations were determined (every other day up to 12 d) by RIA method. Within 4 days of implant administration, there were significantly higher (P<0.001) rates (100%) of pro-oestrus signs (attractiveness without mating) in Group I, than those in controls (zero %). The signs sustained for 9 days without oestrus (mating) in the vast majority (10/11) of implant-treated animals. But, an exceptional goat was in receptive oestrus commenced from the third day following the onset of pro-oestrus. Even so, there was no pregnancy post-mating. The P4 concentrations between the groups remained below 1 ng/ml, regardless of implant treatment. Findings suggest that; i) for the P4 concentrations, there was no marked difference between implant-treated and control groups, as remaining below 1 ng/ml all, and ii) short-acting deslorelin implant could not induce fertile oestrus cycles in coloured Mohair goats during the suckling (anoestrous) season.

Özet

Hipofiz FSH ve LH depolarının, mevsimsel östrus gösteren ırklarda anöstrus sezonu boyunca etkili bir biçimde azaldığı bilinmektedir. Dolayısıyla, bu çalışmanın amacı laktasyondaki keçilerde östrusu uyarmak için deslorelin implant (bir GnRH analoğu) etkisini araştırmaktır. Toplam 21 hayvandan oluşan renkli Tiftik keçisi laktasyon döneminde rastgele iki farklı gruba ayrıldı: Grup I’deki keçilere (n=11, Ovuplant®) derialtı implant (2.1 mg deslorelin) verilirken, Grup II’deki hayvanlara (n=10, kontrol) ise herhangi bir uygulama yapılmadı. İmplant uygulamasıyla birlikte, RIA metoduyla serum progesteron (P4) konsantrasyonları belirlendi (günaşırı 12. güne kadar). İmplant uygulamasından sonraki 4 gün içerisinde önemli (P<0.001) düzeyde pro-östrus (teke ilgisi var, çiftleşme yok) belirtileri ortaya çıktı (Grup I: %100, kontrol: %0). Anılan belirtiler, implant uygulanan hayvanların büyük çoğunluğunda (10/11) 9 gün boyunca devam etti. Ancak, bu keçilerden biri pro-östrus başlangıcını izleyen 3. günde östrus göstererek erkeği kabul ettiyse de, çiftleşme sonrası gebelik şekillenmedi. Öte yandan, serum P4 konsantrasyonu implant uygulamasından bağımsız olarak her iki grupta 1 ng/ml’den daha az bulundu. Elde edilen bulgulara göre; i) P4 konsantrasyonu yönünden, implant uygulamasına bakılmaksızın gruplar arasındaki farkın belirgin olmayıp, her iki grupta 1 ng/ml düzeyinin altında kaldığı, ve ii) kısa etkili deslorelin implant uygulamasının laktasyondaki (anöstrus) renkli Tiftik keçilerinde fertil östrus sikluslarını uyarmada yetersiz olduğu kanısına varıldı.
