When do pelts start to prime?

[223sav]

Wondering what some thoughts are as far as when pelts start to get prime. There would seem to be lots of factors, such as location, daylight length, temperature etc. Is there a ballpark temp that it has to reach for the animal to begin putting on it's fur coat, or is temp not part of it.
I thought I read where the deer rut has to do with daylight, realize that has to do with reproduction, but are there similar things with a coyote's cycle.
Any thought's would be appreciated.

223, it's amount of daylight and your normal temps.

The amount of daylight triggers the growth of fur or hair and the primeness of not only the hair or fur but the hide also. Closing the pores in the hide to keep body temps in vs. in the heat letting the body temp out.

Amount of light is a constant and reliable factor that all furbearers can live and survive by.

Well put Randy that pretty much sums it up.

I read it is the amount of sunlight entering their eyes, sets off a hormone or something that causes the fur to prime up. As the season gets later, shorter days, less sunlight. The mountain ones are supposed to prime sooner, so maybe temperature is also a factor.
