“…In many studies, superovulation response has been achieved in cows with single-dose FSH treatment involving different adjuvants. In these studies, hyaluronic acid (HA, wt 2%) (Tribulo et al, 2011;Tribulo et al, 2012), PVP (wt 25% to 50%) (Takedomi et al,1995;Yamamoto et al,1995) or gelatin (wt 3.2%) (Hill et al,1985) have been used. It has also been re-ported that polyethylene glycol (PEG, 3% to 140%) supplemented with Novocain can be used (Kosovskij et al, 2016).…”

Bu çalışmada adjuvan kullanılarak tek doz Subkutan (SC) FSH uygulamasının ve adjuvan kullanılmadan tek doz epidural FSH uygulamasının kan FSH düzeyleri ve süperovülasyon yanıtı üzerine etkilerinin belirlenmesi amaçlanmıştır. Holştayn inekler (n:18) süperovülasyon prosedürü için üç gruba ayrıldı (n = 6). Gruptaki (İM) hayvanlara 4 gün süreyle 12 saat arayla İntramusculer (IM) azaltıcı FSH (Stimufol, 500 μg domuz FSH ve 100 μg domuz LH, Ulg FMV, Liège, Belçika) dozları verildi. (E) grubundaki hayvanlara epidural aralığa FSH (500 µg) verildi. (SC) grubundaki hayvanlara, 10 mL Montanide ISA 206 adjuvanı içinde FSH eklenerek hazırlanan bir karışım Subkutan (SC) ile uygulandı. Overdeki CL sayısı ultrasonografik yöntemle ölçüldü ve 4 CL varlığına göre süperovülasyon belirlendi. FSH ölçümü için tüm hayvanlardan V. jugularis'ten kan örnekleri alındı. Serum FSH (pFSH) seviyeleri ELISA ile belirlendi. Grup 1'deki tüm hayvanlar, süperovülasyon prosedüründen sonra süperovülasyon tepkisine (4>CL) sahipti. 2. grupta sadece bir hayvan yanıt verdi. Grup 3'te, altı hayvandan dördü yanıt verdi. Kan örneklerinin FSH analizinden sonra, IM ve SC uygulamaları arasındaki fark istatistiksel olarak önemsiz iken, IM ve epidural uygulamalar arasındaki fark istatistiksel olarak anlamlıydı. SC ve epidural uygulamalar arasındaki fark önemsizdi.

“…Hace varios años, se informó que una única inyección de un extracto crudo de hipófisis diluido en un vehículo gelatinasalino, indujo una respuesta superovulatoria similar a la de un protocolo de tratamiento de 5 días, dos veces al día (Hill et al, 1985). Sin embargo, el número de embriones transferibles obtenidos con este tratamiento fue bastante bajo.…”

Despite the fact that research efforts in recent years have led to little or no increase in the number of transferable embryos after superovulation, the protocols that control the emergence of the follicular wave (Bo et al., 1995; and the time of ovulation have allowed the treatment of groups of donors, whatever the stage of the estrous cycle in which they were and has allowed artificial insemination and the transfer of fixed-time embryos (FTAI and FTET, respectively), without the need to detect estrus. The purpose of this work is to review the attempts made for alternative treatments that improve the super-stimulatory response and the simplification of the superovulation protocols in cattle.

Determination of porcine plasma follitropin levels during superovulation treatment in cows

Porcine follicle stimulating hormone (pFSH) and porcine luteinizing hormone (pLH), are widely used to induce superovulation in cows. An advantage of this treatment is that the LH:FSH ratio can be varied to optimize the growth of the ovarian follicles. However, due to the relatively short half-life of FSH, the superovulatory treatment requires numerous injections. A performant radioimmunoassay system (sensitivity=0.2 ng/ml plasma) was used to determine plasma pFSH levels in cows that were superovulated with 2 daily injections of 4 Armour Units (A.U.) of pFSH for 4 d. From plasma profiles, the half-life and the disappearance of pFSH were estimated at 5 h and at 10 to 12 h, respectively, confirming the necessity of using two daily injections.
