Estrous Cycle

This video describes the basics of a cow's estrous cycle. If you're having trouble understanding hormone interactions during different phases of the estrous cycle or what physiological responses said hormones cause, or just would like a review on why the estrous cycle looks the way it does, you're in the right place!

In your diagram at the end, you forgot to make the estradiol surge for the first ovulation to allow LH to surge.

I've seen tonnnns of bovine repro videos (cause I find it super difficult to remember the concepts) but this one is way organized and awesome! Thank you!

The estrus cycle is a lot more harder than I thought

[@deepthi3409]

Much needed video mam so clear and straight to point.Thank youuu😇

[@mehditabatabaee5050]

Great job

[@anne-mariehuster9980]

This video is amazing. The only thing that isn't clear to me is why the Oestradiol only increases exponentially in oestrus - doesn't oestradiol increase exponentially no matter whether it has an effect on the GnRH or not?
Thank you for your help!

[@tfdangerproof9465]

i think the graffian follicle is the reason for estradiol production as long as the follicle is there...andd that's to make the cow show the heat signs

[@yufeigao2838]

Probably because Oestradiol is secreted by follicle which only grows during the estrus period.

Thank for the clear video. When are prostaglandin (PGF2a) produced ?

[@saimkhan6325]

Produce by placenta when corpus letum is regress mean there is no pregnancy there?
