It will be late spring before calves are born from the susceptible window
I was told that the susceptible window was 40 days to 120 days after conception. Midges are around July (possibly June ?) to October. So, say being born 1st January, that puts 40 to 120 days finishing around the end July with a month of midges at the end of the window. 1st Feb around the end of August. 1st March around the end of September. Why will it not be until late Spring before susceptible calves are born ? Have I got this completely mixed up ?
