Factors Affecting Superovulation and Embryo Transfer in Boer Goats*
Despite many studies, results of superovulation protocols are not consistent in farm animals. In this study, 151 Boer goats were superovulated to examine the factors affecting superovulation and embryo transfer (MOET). An optimal regime for superovulation treatment was identified as a 4-day treatment with decreasing dosages of 6-7 mg Chinese FSH or 240 mg Canadian FSH. The 4-day treatment with ...
متن کاملTranscervical embryo collection in Boer goats.
Two experiments were conducted, aimed at improving the practicability of the method for transcervical embryo collection in Boer goats described by Pereira et al. [Pereira, R.J.T.A., Sohnrey, B., Holtz, W., 1998. J. Anim. Sci. 76, 360-363]. Invention of a hammock-like restraining device, use of a wider-bore flushing catheter and a modified flushing mode contributed toward this end. The importanc...
متن کاملFactors Affecting Embryo Transfer Success in Recipient
Recipient age at transfer (less than 525 d old or more than 525 d old), season (fail, winter, spring, summer), method of synchronization (natural or induced), and transfer technique (surgical or nonsurgical transfer) were associated with success of embryo transfer in a log-linear analysis. In a separate analysis, no significant association was found between success of transfer and transfer to t...
متن کاملEmbryo transfer using cryopreserved Boer goat blastocysts
The aim of this trial was to evaluate the effect of embryo cryopreservation techniques on the survivability of embryos and fertility following transfer to Boer goat does. The oestrous cycles of 27 mature recipients Boer goat does were synchronised using controlled internal drug release dispensers (CIDR’s) for 16 days. At CIDR removal, does were injected with 300 IU eCG. The recipient does were ...
متن کاملFactors Affecting an Embryo Transfer Program
A commercially viable cattle embryo transfer (ET) industry was established during the early 1970s. Initially, techniques for recovering and transferring cattle embryos were exclusively surgical. However, by the late 1970s, most embryos were recovered and transferred nonsurgically. Successful cryopreservation of embryos was widespread by the early 1980s, followed by the introduction of embryo sp...
