GB. The area in and around my place was monitored by biologist from Texas Parks and Wildlife as well as from Texas A&M. We were asked to take spikes out for a two year period, shooting everything we seen with anthers 5 inches or longer. Most of the spikes killed were two years old, or older.
Prior to the study I seen herds of 7-8 bucks running together, all spikes. After the first year of killing spikes we didn't see many bucks at all, but continued to kill every spike we seen, anything with a fork was allowed to walk. For a couple of years following we seen a lot of smaller forked deer, at this point we were encouraged to go into an extensive supplemental high protein feeding program. Today I rarely see a spike, the racks are much heavier and we are seeing a lot of 8-10 points, and on occasion a 12-14 point. The yearlings are forked the first year, and a three year old may sport a 6-8 point rack. I hate to sound redundant, but again, it is all in maintaining good genetics to produce quality deer. Several years ago I killed a 19 pointer, could arguably even be classified as a 21 pointer, so removing the spikes, and supplemental feeding has payed off in my opinion. I will try to scan the picture and post it if I can figure out how to do it.
As mentioned before, deer hunting in Texas has become big business. Everyone wants a BIG buck, it the interest of producing the bigger deer it is absolutely necessary to remove those of inferior quality.
