I started a self maintaining study with 7 out of a herd of 19. I trimmed in September

and not again until June.  What I learned is the body in cooler climates must redirect

the energy to grow hooves and focus on coats and warmth.  I wondered if it could

be cold or lack of sunlight. 

I concluded that it is both.  In april I noticed the walls began to elevate above the sole.

And by May when we had better weather and longer days the feet grew a normal 3/8

inch a month.

The collage of feet above are 6 months out from the last trim.  The, winter muck snow

and ice made beautiful bevels around the capsule.  The frogs became weak and packed

down into thefoot.  The interesting thing about the frogs was the intertubular horn allowed

the frog tubules to separate like a batch of "angel hair noodles".  I was able to see the root

source and also the volume that emerges next to the bar at the bottom of the collateral groove.
