Will someone please tell me how often will a cow come in heat? Also how soon will a cow come in after she has a calf? Thanks

With post calving heat it can be areal variable. Some as soon as 2 weeks post calving but generally probably around 30 days (or so).
One of the magic catches to all this is that as soon as you start planning around specific time frames the girls will change.

Do you find cow cycles are affected by drought, or other things ?
