متن کاملComparing three superovulation protocols in dromedary camels: FSH, eCG-FSH and hMG
The objective of this study was to compare three superovulation protocols in dromedary camels. Follicular waves of dromedary camel donors (n=6) were synchronized using two GnRH injections. Superovulation was initiated 2 days after the second injection (day 0 of experiment). The experiment was conducted using change over design, where all females received three superovulation treatments one afte...
متن کاملOvulation, fertility and prenatal mortality in heifers treated with PMSG or porcine FSH.
Ovulation rate, fertilization rate and prenatal mortality were studied in yearling beef heifers treated with PMSG or FSH and in non-treated controls. Oestrus was synchronized in 50% of the animals in each treatment with an oral progestagen. The gonadotrophin injections were given during the normal oestrous cycle or during the progestagen-administration period. All heifers were inseminated 6 to ...

In the conventional methods, follicular stimulating hormone (FSH) is administered to donor cattle twice daily for 3 to 4 days. As this method is labor intensive and stresses cattle, improving this method has been desired. We previously developed a novel and simple SOV method, in which the intr...
