Question: When a superovulated cow exhibits heat before or after the predicted date should we still breed her?
Answer: Yes,if she is two days early or one day after the predicted date it is possible to retrieve transferrable quality embryos.

Question: If a donor shows some signs of heat at the predicted time of heat but does not stand,should we still breed her ?
Answer: Not unless she actually stands to be mounted . When they only show secondary estrous signs at the time of heat the donors usually do not ovulate. Just inject PG to initiate a new cycle .

Question: Who sells the "best' FSH? Are there "weak" or "stronger" batches of FSH?
Answer: There are no measurable differences in donor responses between batches or brands of FSH .Any small differences between FSH manufacturers or brands are eliminated by the large variable ability of cows to respond to injected FSH. We even found in controlled experiments very little difference between FSH ( a small protein with a half life of only a few hours) and PMSG ( a large protein with a half life of 15 days) .
