[Prairie_Beef] Natural cycle for beef?

[Kevin Carpenter]

Hi all.

I'm making my second pass through "Grass-Fed Cattle" (2006 by Julius
Ruechel).

He advocates syncing cattle up with there evolutionary schedules,
including a late spring/early summer birth cycle (around the time most
wild prey animals like deer tend to give birth).  Doing so is claimed to
have significant benefits, including (mostly) natural weaning cycles, the
ability to graze cattle on reserve winter pastures (even through snow),
little need to supplement feed during the winter, compensatory weight gain
in spring (e.g. Allow the cattle to burn fat in the winter - its why they
store it, and like a human after a diet, the weight will come back very
quickly when the food supply increases in the spring), etc.

He acknowledges that shifting to this schedule will cost most ranchers a
year of income, but the reduction in input cost should nicely compensate
for that (e.g.  No need to have haying equipment).

Since I'm just getting started, with 5 cows, 2 heifers now, and three more
heifers soon - I'm curious what people think of this approach?
