Les mâles de 1 an et demi qui avait 3 pointes d'un côté ( donc ceux avec le plus grand potentiel)
Si on base une étude sur cette affirmation, elle n'a pas grand valeur, en tous cas selon l'étude qui suit:
Yearling buck antlers, can they predict adult antler size?
When it comes to yearling buck antlers, there are two schools of thought: the “once a spike, always a spike” crowd and those who disagree. Some believe that spike or small antlered yearling bucks are “inferior,” meaning they lack the potential for future antler growth compared to those yearlings that produce larger antlers. A recent article published in the Journal of Wildlife Management in 2008 titled “Juvenile-to-Adult Antler Development in White-Tailed Deer in South Texas” might finally put an end to the debate.
Most of the previous studies on antler development have been conducted on captive deer. The objective of this research was to determine if a whitetail male’s first set of antlers was a good predictor of antler growth at maturity (≥4.5 yr old) in wild populations. The study was conducted on 12 different sites over an 8 year period. Males were captured as fawns or yearlings and individually marked for identification. They were then recaptured annually to gather antler measurements as they aged. Hundreds of deer were captured and followed until they were 5.5 years old or older. So what did they find? By the time a white-tailed male reaches 4.5 years of age, there is no difference in antler measurements regardless of the size of their first set of antlers as a yearling. The study compared yearlings with ≤3 antler points to those with ≥4 antler points. While all measurements remained smaller in yearlings with ≤3 antler points at 2.5 and 3.5 years old compared with those with ≥4 antler points, by the time they reached maturity at 4.5 years old, those differences disappeared. In fact by their third set of antlers, ≤3 antler point yearlings appeared to be accelerating their antler growth at a faster rate than the ≥4 antler point yearlings. Judging the future potential of a buck based on his first set of antlers is like the NFL drafting 6th graders. At either age, you really do not know how big the individual will be at maturity. Some individuals just take more time to realize their full potential.
