Why Are There Annual Cycles In Antler Growth?
Believe it or not, the 23 degree tilt of the Earth¹s axis is the ultimate cause for the annual cycles in deer antlers. This tilt is what causes
Earth's annually recurring seasons. Deer have adapted their physiology and
behavior to these seasonal changes, including antler growth. The environmental cue that regulates antler growth is the amount of day length, or photoperiod. The physiological cue is the male hormone testosterone. The way this works
is complicated, but changing day lengths are sensed by the eyes, which sendd this message, via the optic nerve, to the pineal gland. The pineal
gland - a pea-sized organ at the base of the brain - produces many different hormones. One hormone produced is luteinizing hormone, which
controls the amount of testoserone produced in the testes. The antler cycle lags behind the changes in day length because the hormonal changes take time. During fall, decreasing day lengths cause
melatonin production to increase, resulting in decreased production of both luteinizing hormone and testosterone. Decreasing testosterone levels
then cause the antlers to shed

I figured this would be informative but it seems more people are conserned with controversy and gossip these days than real hunting information[rofl]

So then, the bucks who have mated the most or the least will ultimately loose their antlers first?

I believe so, I read a long time ago that the dominant bucks that are rutted out and bred first are generally the first to drop their antlers.

Grit to answer your question yes.

It all depends on the photoperiodism and the drop in test. Once the test drops the horns will come off.

Chris Quite possibbly yes. Every property and deer is different.

The best time to kill a dominant buck is during the month of October when they are marking territory and establishing rublines. As the season gets later and the rut gets in full swing it gets tougher and tougher.

You know, it's funny. The buck I have been after all season is rubbing every tree in my area. I keep expecting to get a pic of him with out his antlers but he is still hanging on to them. He has lost a lot of weight from what I can see in the pics. If he makes it through today I think he will shed very soon. I was thinking he has been rubbing to get rid of the antlers. I have litterally found 50 huge new rubs in the past 5 days. He is hitting trees 10" in diameter and really tearing them up. Wonder if he is rubbing so much to drop them.

So let me hear this again this theory that is being preached as gospel? I don't buy that for one minute because not every buck looses there antlers like this that are breed out until they are pushed off by the growth of the new horn. It makes sence to me when something rises it's going to push on something upward.

The bone becomes brittle in the cold because of the lack of blood that once flowed to the bone that brought it the minerals for growth. That could explain why when a deer falls to the ground after being shot the horn just falls off or breaks off no matter how you want to look at it.

Lets face it someone studied this and come up with a theory is all and it's not written in stone. I seen good bucks at the end of march who still had there bone and I'm sure they had done their share of breeding.

Man always wants to come up with answers and then write about it to make thereself look like they have some knowleage. For this very reason the medical community dispells common beleifs everyday about diseases they felt were true and then later found out that they weren't when they advocated that they were.

Someone made a statement to believe nothing of what you here and only half of what you see.

To make statements from what others write and then believe it I'm not so sure thats good enough?

Thats why I call hunting and fishing books comic books. Yes I read them but don't believe a lot of things with them because in my experiances I fould not all things to line up the way they say.

To each his own Cat. This has biological backing though.

What I'm saying is they could be wrong as well and based on what some of us have seen things are not always the same. They say its backed up but still to a degree it's a theory they say that is the cause though correct?

I know I have thought some things then something happend for me to say well so much for that theory that went out the window.
 
#20 ·
Well could it be a combination of things as well too? Not one thing in stone as we sometimes believe. I know I saw something I thought was strange this year and didn't realize what I saw until the other day it dawned on me that it was a shed buck as well. He was maybe 110 and I looked at the deers head not studying its face and saw the the round spots and now realize that it was a shed? That certainly wasn't any big buck or breeder for that matter I felt. This was back before thanksgiving and because it was so early didn't think about a shed at all.
 
#21 ·
Yes Cat it definitely is a combination of things. And Yes this is a theory. Poor nutrition can also cause a buck to loose his horns early.

I've been hunting a long time and I spend a lot in the woods and read alot.

It's not my own never said it was
