The primary effect of drought/limited forage on antler growth is body condition coming out of winter when new antler growth starts. Effects of this year's drought, if any, will be most evident in next year's antler growth - and can be canceled out by a mild winter. The effect in antler growth is seen most often in reduced mass at the bases and reduced beam length, and is usually pretty subtle. It is greatest in yearlings, then 2 year-olds, then geriatrics/regressors; dominant bulls are least affected. The pattern is similar, but with greater effects in deer.
