[QUOTE="BSK, post: 5058182, member: 17"] The stress of the rut is driven primarily the adult sex ratio, but also to a lesser degree the buck age structure. When many more does are present per buck, the rut stretches out over a longer period; i.e. months instead of a weeks. This prolonged breeding activity increases the duration of chasing and heavy weight loss in bucks. And as for the buck age structure, mature bucks have the body weight to spare for the rut, and when they are present, they do more breeding than younger bucks do. This saves the younger bucks from heavy rut stress and the life-long reduction in performance that is seen from bucks that are more stressed while their young. Those two factors can be "managed for" (improved through harvest selection). However, one MAJOR rut stress factor that cannot be altered is the terrain. I have a growing body of evidence form trail-camera censuses that bucks who live/rut in very steep/rugged terrain do not live as long as bucks in flatter terrain. I strongly believe all the chasing in steep terrain is far more stressful than chasing on flat ground. This greatly increases stress and makes post-rut survival less likely. [/QUOTE]
