I have a wonderful French Charolais cow, who is a great calf raiser.
She is currently in an IVF facility in Quebec.
She was born 18 January 1998 in Clyde, Alberta, Canada.
She is in superb physical condition, although at this advanced age (16) she isn't producing very many eggs per flush.
We've decided to go to a 1X per month regime, to allow her more rest time between IVF procedures.
They've agreed to use a lunar phase calendar to time the egg retrieval and/or insemination.
My question is; where I might find out the most fertile time of the month for the procedure. Also is it the time of the egg aspiration or time of the insemination(24 hours later)), that is important in determining the fertility.
Thanks in advance.
I think that the most fertile time would be under a waxing Moon (between the new and the full) in a water sign (Cancer, Scorpio or Pisces). The Moon generally stays in a sign for two days so it could cover a 48 hour period.
Thank you very much for publishing such an informative table. Among the farm animals listed above, I like goats very much.
