Culling Study Complete

[TX300mag]

The most comprehensive study on culling to date has been completed. This podcast is fascinating. I'm interested in hearing your thoughts.

I won't sun up conclusions, but The Comanche Ranch in south TX (over 100K acres) just completed a 13 year study. One group culled yearlings with inferior antlers, another group culled 3.5 year old with inferior antlers, and control group did not have any bucks culled.

These deer were caught, measured, and either released or culled. This was done by helicopter and scientific study, not hunter observation and kills. They believe they accounted for nearly every buck on each area. The top 6% of bucks on the first group were left to breed.

Well over 1000 bucks were culled during the first seven years.

Thanks docpoco. I was listening on the way to work this morning while driving so I wasn't in a position to take notes. I'm going to listen to it again to really soak it all up.

And then I'm going to go alter the genetics of the 161,000 place I'm hunting with my spike tag. [emoji1363]

First off this is a must listen! Thanks for sharing.

My takeaways;
-Culling doesn't work...duh
-extremism on the culling side can eventually run your herd into extinction
-Genetics can be greatly suppressed by the environment
-Age is key to big antlers, environment fully expresses them
-wait until they are at least 3.5 to kill
-Breeding value is a new term to me and is probably the most informative aspect of this podcast

Basically this is a case for older age class if antler size is of importance.

*not once did they mention soil [emoji13]

Episode 31 sounds relevant as well, "eating deer in a CWD world". That's my next listen.

I listened to that one a couple days ago. My take was that money is no object in the pursuit of antlers in TX!

Seriously, Deer U podcasts are a good resource for habitat managers.

Yeah, I can't imagineer what that study cost.

Breeding value is a game changer. 30% of the time traits flip/flopped where large antlered bucks sired smaller antlered males and 30% flip/flopped the opposite.
