How acorns help is that the deer leave winter in much better shape so they can put more resources into antler growth instead of going the damage control route...
When you understand the science of how and why deer grow larger antlers, the above statement makes a ton of sense. With all due respect to Baker, because I know that HE already knows this, the clover deer are eating as they grow antlers is not what determines the relative growth thereof. Think about it; if all a deer needed to grow really big antlers was perfect nutrition while they were growing, every yearling buck on quality range would grow the biggest antlers of his life. Why is it they don't grow their biggest antlers until later in life? It's because they are balancing the requirements of body growth and antler growth, when they are younger. It isn't until a buck has reached full maturity in his physical frame that he can afford to divert huge amounts of calcium from his skeletal system to growing out-sized headgear. During that time, the protein, calcium and other nutrients needed to grow antlers is quickly recovered by an optimum diet.
To put it in simpler terms; Baker sees bucks growing large antlers on his managed property because they have everything their bodies need to grow, from the moment they are conceived. They grow those antlers because their bodies are in optimum condition during the process; they replace the lost nutrients from optimum nutrition during the antler-growing period. It's important to understand that body condition created by optimum nutrition is the cause of larger antlers, not the food consumed during the time antlers grow. This is why you frequently see larger-racked bucks the year after a very good acorn crop; those bucks had better body condition the following spring with which to grow bigger antlers.
Achieving the same thing in a free range herd, particularly one with a significant winter stress period, would not be so easy. Even if the deer were in a large enclosure, fed an optimal diet all year long, the simple requirement of burning calories to keep warm instead of growing a larger body size would mean smaller antlers (relative to body size) would be grown the following year.
This is where woody browse (as found in the young shoots of early successional growth) can be so valuable to northern deer. It is the handful of calories in each bud nipped off that keeps deer from suffering the body mass reduction that accompanies starvation, or limits those effects. This results in larger, healthier fetuses, and the potential for bucks with larger body mass that can contribute to bigger antlers. Personally, I am focused on healthy fawns and large-bodied deer. If that results in bucks with more substantial headgear, that's not an unwelcome fringe benefit.
