ovarian response - Opis:
- Response to the superovulatory hormone treatments varied for the type of breed and doses of superovulatory hormone used. Ovarian response of 42 crossbred HF (50%, 75%) and pure dairy cows were evaluated based on ultrasonographic count of CL and embryo recovery for quality assessment. Ovarian response rate was significantly higher (P<0.05) in the crossbreds than in the pure bred cows. The maximum response achieved (CL count, mean ± SE) was 14.6±1.1 and the least with 11.2±1.1, 75% HF at 650IU and pure HF at 800IU, respectively. Significantly higher (p<0.05) number of UFO were collected at a dose of 500 IU while transferable embryos were higher at 650IU in both the 50% HF and 75% HF cows. Pure bred cows responded fairly with more CL and produced higher number of transferable embryos at a dose of 800 IU FSH. In conclusion, the optimal dose for maximum response (CL count) exhibited in cross breed HF cows is 650 IU.
