                            <p>Bu çalışmada farklı kriyoprotektanların, yavaş dondurma yöntemi ile dondurulup çözdürülmüş Saanen keçisi embriyolarının canlılığı üzerine etkilerinin belirlenmesi amaçlanmıştır. Çalışmanın hayvan materyalini 15 baş Saanen ırkı keçi ve 3 baş teke oluşturdu. Keçilere siklusun dönemi gözetilmeksizin 12 gün süreyle fluorogeston asetat (20 mg) emdirilmiş intravaginal sünger yerleştirildi. Sünger uygulamasının 9. gününden itibaren 3 gün süreyle 12 saat arayla azalan dozlarda folikül uyarıcı hormon (FSH) (5050; 30-30; 20-20 mg) kas içi yolla enjekte edildi. Sünger çıkarıldıktan 24 saat sonra doğal aşım yaptırıldı. İlk aşımdan sonraki 7. gün laparatomik uterus yıkaması yapılarak embriyolar elde edildi. Toplanan embriyolar 3 farklı kriyoprotektan [etilen glikol (EG), gliserol ve dimetil sulfoksit (DMSO)] kullanılarak yavaş dondurma yöntemiyle donduruldu. Çözdürülen embriyolar 38.5 ºC’de %5 CO2’de inkübasyona bırakıldı ve 24, 48 ve 72. saatlerde canlılık muayeneleri yapıldı. Çalışmada süperovulasyon cevabı (≥4 Cl) %93.3, embriyo toplama oranı %72.3, transfer edilebilir embriyo oranı ise %58 olarak belirlendi. Dondurulup çözdürülen embriyoların 24, 48 ve 72. saatlerdeki canlılık oranları EG’de %64.86; %56.76; %54.05, gliserolde %54.55; %45.45; %36.36, DMSO da ise %46.88; %40.63; %28.13 olarak belirlendi. Embriyoların 72. saate ulaşmalarında EG ile dondurulanların gliserol ve DMSO ile dondurulanlardan istatistiki olarak daha iyi olduğu tespit edildi (P&amp;lt;0.05). Saatlere göre blastosistlerin yaşama oranları EG’de %76; %64; %60, gliserolde %54.6; %45.5; %36.4 ve DMSO’da %42.1; %36.8; %21.1 olarak belirlendi ve 72. saatte EG ve DMSO arasında farkın önemli olduğu görüldü (P&amp;lt;0.05). Yapılan çalışma sonucunda çözdürme sonrası 24, 48 ve 72. saatlerdeki canlılık oranları EG ile dondurulan embriyolarda diğer kriyoprotektanlarla dondurulanlardan daha yüksek olduğu belirlendi</p></trans-abstract>

The study was conducted on 15 Saanen goats and 3 bucks. Fluorogeston acetate (20 mg) impregnated intravaginal sponges were inserted in goats for 12 days regardless of the sexual cycle. Starting on the 9thday of intravaginal sponge administration, follicle stimulating hormone (FSH) was injected intramuscularly, every 12 hours at decreasing doses (50-50; 30-30; 20-20 mg) for 3 days. Goats were mated naturally 24 hours after removal of the sponges. Embryos were recovered by laparotomic uterine flushing on the 7th day after the first mating. Collected embryos were frozen by using 3 different cryoprotectants [ethylene glycol (EG), glycerol, and dimetil sulfoksit DMSO)] with slow freezing technique. Thawed embryos were incubated at 38.5 ºC and 5% CO2. The viability of embryos was evaluated at the 24th, the 48th, the 72nd hours after thawing. Superovulation response (≥4 Cl), embryo recovery rate and transferable embryo rate were found to be 93.3%, 72.3% and 58%, respectively. Viability rates of frozen and thawed embryos at the 24th, the 48th, the 72nd hours were found respectively to be 64.86%; 56.76%; 54.05% in EG group, 54.55%, 45.45%; 36.36% in glycerol group and 46.88%; 40.63%; 28.13% in DMSO group. Viability rates of the frozen embryos with EG were statistically better than embryos frozen with glycerol and DMSO (P&amp;lt;0.05) at 72nd hour. Survival rates of blastocysts frozen were 76%; 64%; 60%; 54.6% in EG group 45.5%; 36.4% in glycerol group, and 42.1%; 36.8%; 21.1% in DMSO group and at 72nd hour the difference between EG and DMSO group was significant (P&amp;lt;0.05). In conclusion, viability of embryos at the 24th, the 48th, the 72nd hours after thawing in EG group was significantly higher than the embryos frozen with other cryoprotectants</p></abstract>
