In my last post we brought our cow through from just having given birth back to normal conditions to begin cycling again.
Now it’s time to discuss how that works and see what’s going on beside mounting all over the place flattening grass.
There are quite a few names going to be tossed around so here’s a quick reference if you need it:
Oestrus-the actual heat event
Estradiol-what makes the cow show all the signs of heat
Corpus Lutuem (CL)- The yellow body formed after ovulation
Corpus Albicans- the white remains of a regressed CL
Graafian Follicle- what the egg is stored in from birth to the heat it matures in
Prostaglandin (PGF2α)- the hormone that resets the cycle by regressing the CL, found in Estrumate and similar products
