“…Synchronization of estrus in female goats has been achieved through administration of progesterone or its synthetic analogues, with a vaginal device or a subcutaneous auricular implant [19][20][21][22] . The combination of equine chorionic gonadotropin (eCG), prostaglandin F2α (PGF2α) and progestagen treatments eliminates variability in goats' ovulatory response, increases production of ovulatory follicles and ovulation rate, and improves fertility 19,[22][23][24] . İnce and Köker 25 reported that treatment with progestagen in conjunction with PGF2α and eCG was convenient for estrous synchronization of Turkish Saanen goats during the breeding season in Turkey.…”

The objective of this study was to compare the efficacy of diff erent estrus synchronization protocols on reproductive parameters in nulliparous Saanen goats at the end of the transition period. In this experiment, 71 nulliparous Saanen does were used and divided into four treatment groups as norgestomet implant plus GnRH (Imp-G), norgestomet implant (Imp), FGA sponge plus GnRH (Spo-G), and FGA sponge (Spo). The progestagen treatments were administered for 11 days. At progestagen withdrawal, all does were injected with 360 IU of eCG and 125 μg of PGF2α. At the end of the treatments, all the does were joined with fertile bucks. There were no significant diff erences (P>0.05) in reproductive parameters among the treatments groups. Does were in estrus within 29.2±0.36 h for all the treatments combined. It was concluded that, the use of norgestomet implants and FGA sponges in combination with eCG and PGF2α were eff ective for estrus response, onset of estrus, fecundity, prolificacy, and fertility in nulliparous Saanen does at an age of 7-9 months under local conditions at the end of the transition period also GnRH was found to be ineff ective in increasing the reproductive parameters. Keywords: Estrus synchronization, GnRH, Nulliparous Saanen goat, Progestagens, Transition period Geçiş Döneminin Sonundaki Nullipar Saanen Keçilerinde Farklı Progesteron Analogları ve GnRH Uygulamalarının Reprodüktif Parametreler Üzerine EtkinliğiÖzet Çalışmada, geçiş döneminin sonundaki nullipar Saanen keçilerine uygulanan farklı östrus senkronizasyon protokollerinin reprodüktif parametreler üzerine etkilerinin karşılaştırılması amaçlandı. Çalışmada 71 adet nullipar Saanen keçisi kullanıldı ve keçiler rastgele 4 gruba ayrıldı: norgestomet implant + GnRH (Imp-G), norgestomet implant (Imp), FGA sünger + GnRH (Spo-G) ve FGA sünger (Spo). Progesteron tedavileri 11 gün süreyle uygulandı. Progesteron tedavilerinin son günü tüm keçilere 360 IU eCG ve 125 μg PGF2α yapıldı. Tedavilerin sonunda tüm keçiler fertil tekeler ile çiftleştirildi. Tedavi grupları arasında reprodüktif parametreler açısından istatistiksel bir farkın olmadığı belirlendi (P > 0.05). Tüm tedaviler değerlendirildiğinde keçilerin 29.2±0.36 saat içinde östrus gösterdiği saptandı. Sonuç olarak, yerel çevre şartlarında yetiştirilen ve geçiş sezonunun sonunda bulunan 7-9 aylık nullipar Saanen keçilerinde norgestomet implant ve FGA süngerin eCG ve PGF2α ile birlikte kullanılmasının östrus oranı, östrus başlangıcı, fekundite, prolifikasyon ve fertilite oranları bakımından etkili olduğu; GnRH kullanımının ise fertilite parametrelerinde artış sağlamadığı belirlendi.

“…The body weights of does were 48.5 ± 8.11 kg (means±SD). Oestrus was induced and synchronized using the method by Özer and Doğruer (2011). Pregnancy tests were carried out on the 45 th day of pregnancy using a real-time ultrasonography device (Pie Medical, Falco, The Netherlands) equipped with a 5-7,5 MHz linear rectal probe transrectally after completion of the matings.…”

Fatty acids are very important biological substances due to their metabolic, structural and signaling functions. Omega-3 has different beneficial, harmful and neutral effects on adipokines. Adipokines have autocrine, paracrine and endocrine effects on metabolism. In the study 54 German Fawn x Hair crossbred goats were synchronized using intravaginal sponges. During the first period (mating-75 days), all animals were fed a diet supplemented with protected fat and during the second period of pregnancy (76 days-kidding), one of the groups was fed a diet supplemented with fish oil and other was fed a diet supplemented with protected fat. Serum leptin, ghrelin, adiponektin and omentin levels were measured by ELISA system. Distributed fed (roughage and concentrate) were sampled and dry matter, crude protein, fat, and ash were determined by AOAC (1988) analysis methods. The Acid Detergent Fiber (ADF) and Neutral Detergent Fiber (NDF) analysis were conducted using heat stable α-amylase and sodium sulphite. Fat source (fish oil or protected fat) affected feed consumption and the highest feed consumption was found in the group fed with protected oil first half of the pregnancy and with fish oil in the second half of the pregnancy and in the fish oil group during the pregnancy. It was determined that the use of fish oil during pregnancy did not affect ghrelin, leptin and omentin concentrations in serum. Adipokine levels of fish oil fed animals during any period of pregnancy were found to be high and it was also found that serum adiponectin levels in goats fed with diet containing fish oil in the first half of pregnancy and protected fat in the second half were statistically significantly high in adipokines.
