Re: Antler Growth
If a deer has met all nutritional requirements, especially with crude proteins, it can grow that much in a day. Remember; its "peak" antler growth, and we are talking beam and other circumference diameters in addition to main beam and tine length.
This is especially true for bucks whose bodies are fully developed beyond 4 years of age. Prior to that point their bones aren't fully developed; so they "borrow" calcium from their bones for antler growth. Its a self imposed osteoporosis that they recover from well, and scientists are learning from.
I'll see if I can find an easy to read paper on it.
