I only have experience with westerns, all of which are captive bred (many were bred by myself).
I put all of my year+ old hogs through a brumation whether or not I intend to breed them; simply because that is what they would naturally experience. 3-4 months of no fasting isn't really a feeding issue, as much as it is just a normal process for westerns. (Not sure if Mexicans have the same sort of yearly brumation as westerns).
Love to hear more about your experiences with westerns vs. Mexicans; I know they are very similar.
I never asked how many you had worked with, rather I stated the sample of westerns I have had experience with and stated that I had not experienced the same results as you have. That wasn't a stab at you or your response, I just stated that I had not found the same results. If you have worked with hundreds of hogs more than I, than it is intirely possible you have found different results.In fact, I know that Gregg Madden specifically recommends a hot spot temp higher than 90 degrees. Should we ask him how many heterodon he's worked with too?
