How Hot is too Hot for the Buck?

I've read that bucks get frigid when they get too hot. Just how cool do you have to keep them to be sure they will perform mating duties?

Goats, overall, tend to be seasonal breeders.  I am not aware of temps being a strong factor.  Generally August to Dec tends to be breeding season....much depends on the specific breed.   And such generalities are sure to produce exceptions.  My Nigerian Dwarfs, for example,  have never heard of a breeding season.

John, he's talking about rabbits

My first thought, on reading the title, was of deer.

Oops!!!  I should have read the entire heading.  I have been dealing with brother and sister Nigerians .....three weeks old.  I am pretty sure it will be on TMZ and the front page of the National Enquirer.

They don't necessarily get "frigid," as they will be willing to breed; however fertility begins to decline at 75°F. with them becoming temporarily sterile at around 85°.F The more you use the buck, the longer he will maintain fertility. But after a week or so at 85°+with no breeding they typically become, what rabbit breeders call "heat sterile."
Of course that's not a "magic number" for all bucks. Environmental variables and genetics will also play a part in the buck's fertility.

Look into rabbits with big ears. Also lock for ways to cool off your rabbits. I have 80% shade cloth around them and wool blanket to block out the sun completely. Going to plant sun flowers to block out more light and some trellising plants. Also look into misters.
