“…The current result was consistent with some reports in which the proportion of high-quality embryos is inversely associated with the responsiveness of cattle for superovulation (20,22). When comparing with other studies conducted with different FSH protocols, transferable embryo proportions in present study were lower than in breeds of Sistani (49%), Angus (52%), Finnish Ayrhire (61%), Holstein (54%), Korean native (62%) and Japanese Black (53%), (6,26,31,34,37,41). However, similar results were reported in Nelore cows (1, 7).…”

Summary:The present study was designed to determine whether a single epidural injection plus intramuscular (im) injection of FSH in order to reduce the number of injection treatments required to induce supurovulatory response, as well as to determine the effects of this treatment on Anatolian Black cow (Bos Taurus). The results will be compared to those obtained by administration of twice daily injections of FSH. Twenty-one Anatolian Black cows were used in this study. Anatolian Black cows received Cue-mate containing 1.56 g progesterone. The cows were divided into three groups (D1, D2 and E) based on the dose and administration route of FSH. In group D1 a total of 490 IU FSH and in group D2 a total of 700 IU FSH was given intramuscularly in decreasing doses for twice daily for 4 days. In both groups superovulatory treatments were initiated on day 7 of the cycle. In group E, FSH was given 175 IU epidural plus 175 IU im injection on day 7 of the cycle. On the 9th day of the cycle, the Cue-mate was removed and the cows received 500 µg prostaglandinF2α in all goups. The cows were artificially inseminated (AI) using semen obtained from native Anatolian Black bulls twice; in the evening of day 11 and in the morning of day 12 with 12 hours intervals. Superovulated cows were non-surgically flushed 7 days after AI. Embryos were morphologically evaluated and classified according to the criteria recommended by the IETS. No significant differences were observed in the mean number of Corpus luteum (CL) among groups which were 3.7 ± 0.56 in D1; 3.4 ± 0.55 in D2 and 6.0 ± 1.14 in E . There was no difference in transferable embryo yield among groups (10/42, 23.8% in D1; 14/32, 43.8% in D2 and 19/82, 23.2% in E). Untransferable embryo yield was not also significantly different among the groups (32/42, 76.2% in D1; 18/32, 56.2% in D2 and 63/82, 76.8% in E). The UFO rate was similar in all groups (17/77, 22.1% in D1; 13/71, 18.3% in D2 and 28/132, 21.2% in E). Recovery rate was found to be significant among groups (59/77, 76.6% in D1; 45/71, 63.4% in D2 and 110/132, 83.3% in E). To conclude, a single epidural injection plus an im injection of FSH application can be obtained acceptable results compared to twice daily injection of FSH for superstimulatory response. However transferable embryo rate of Anatolian Black cow was found to be low in both single epidural injection plus im injection and twice daily FSH applications. Further studies are required to obtain more concrete results on increasing transferable embryo yields in different breeds.Key words: Cow, embryo, epidural injection, FSH, superovulation.İntramuskuler uygulama ile birlikte epidural boşluğa uygulanan FSH'nın Yerli Kara inekte süperovulasyona olan etkisi Özet: Bu çalışma süperovulasyon oluşturmak için tekrarlanan dozlarda yapılan FSH uygulama sayısını azaltmak, FSH'nın tek uygulama şeklinde epidural-im olarak uygulanmasının süperovulasyon oluşturma yönünde etkisini belirlemek ve bu uygulamanın Yerli Kara inekte etkisini ortaya koymak amacıyla tasarlandı.

“…Whereas other reports have shown there is no effect of gonadotropins doses (FSH) on embryo quality (Barati et al, 2006). There are several reports which indicate that Bos Indicus breeds have been shown more sensitivity to exogenous goandotropins than Bos tauruts cattle (Randel, 1984) and lower doses of FSH for could be applied to Bos indicus cattle compared to Bos Taurus cattle (Lewis, 1992;Barros et al, 2003;Barati et al, 2006;Nilchuen et al, 2011) The development of practical approach to achieve enhanced responses to superovulation protocols still requires further research, especially in indigenous cattle breeds such as Omani cattle breeds Inducing superovulation is usually done by multiple injection of follicle stimulating hormone (FSH) in 12 hour intervals to achieve high ovulation rates. Induction of super ovulation and the yield of maximum number of good quality embryos are most important factors for the success of embryo transfer.…”

The experiment was conducted to investigate the Ovarian response and embryo quality using different doses of follicle stimulating hormone (FSH-P) in North Omani Cattle breed (NOC) in order to determine the suitable dose. Eighteen donor NOC were divided into three groups (G1, G2, and G3) comprising of six cows in each group and treated with 20 (G1), 25 (G2) and 30 mg FSH (G3). Ovarian response was recorded as development of corpus luteum (CL), unovulated follicles (UOF), unfertilized ova (UFO), recovered embryo (RE) and transferable embryos (TE). Embryos were flushed seven days after the first AI and classified according to the developmental stage and quality. Results showed that, cows superovulated with FSH (G3) increased significantly (P<0.05) number of CLs and number of RE (6.83 and 5.33 /flushed cow) compared with the G1 of FSH (3.17 and 2.00/flushed cow) and G2 (4.67 and 3.00/flushed cow). While using FSH in (G2) increased significantly (P<0.05) the number of TE (excellent and good) quality, decreased average number of UOF and UFO (2.84, 3.33 and 0.67/flush) compared with FSH G3 (1.83, 5.67 and 1.50/flush). While no significant difference was observed in TE number between G1 and G2. G3 groups producing embryos at early stages of development (4 and 8 cells) and this was undesirable for embryo transfer program as this treatment (30 mg) produced more number of fair, poor and degenerated embryos compared with 20 and 25 mg FSH. Consequently, 25 mg FSH dose increased number of TE, decreased number of UOF and UFO, and that was the suitable dose for superovulation of NOC.

“…Previous studies documented that reproductive performance of dairy (Sartori et al, 2002) and beef (Wolfenson et al, 2000) cattle can be influenced by season of the year. It is reduced during the hot summer months, which can be the result of changes in follicular growth, corpus luteum function, expression of oestrous behaviour, superovulatory response, quality of embryos and fertility (Armstrong et al, 2001;Webb et al, 2004;Barati et al, 2006). Alberghina et al (2013) detected significant effects of ambient temperature and relative humidity on selected blood metabolites related to the functional metabolism of dairy cows.…”
