In the
fall, make a decision which field will “winter” your cattle.
In general, the least value of your pastures should become the winter
“sacrifice” pasture, where round bales can be unrolled for cows to eat (what
they sleep on becomes soil-building organic matter) and then, while grass comes
on in the spring, all the “pugging” of a wet pasture is contained in one field.
Plan on seeding summer annuals into the winter sacrifice pasture. You may need to disc it over to smooth
off all the pugging holes, but that makes a seed bed for sudangrass, sorghum-
sudan crosses, or millet that (if seeded by early June) will be big enough to
feed all your cattle during the heat of the summer when grass slows into
near-dormancy growth (this will be very much a problem with this year’s dry
spring conditions).
As soon as soil is firm, move cattle into better pastures. In fact, your smallest or irregular-shaped
pastures need the cattle first, and here is why: bigger pastures (rectangular
shaped) can be bale harvest most easily. With the weather conditions prevailing
this spring, grass hay could have been cut by the 15th of May. By
now they would have a good second growth and offer some early summer grazing
before the summer annuals would be needed.
It is unsound harvesting to cut your alfalfa first. Even the newest grasses will still push
heads two weeks ahead of alfalfa first-buds.
Of you leave grass fields to bale last, you not only will sacrifice much
of the protein content into the seed head, the plant may go dormant for most of
the rest of the season.
Properly
rotated vegetative grass may provide you six grazing passes per season per
pasture. This is twice the potential feed you
are likely to harvest from a three-cutting hay making system. It is our alfalfa-based approaches to hay
making that are causing us to undervalue and underuse the fertility capability
of a rotated, fertilized pasture system.
Unless you grow alfalfa to resell to dairy herds, do not worry about
cutting it full bloom. Early
cut alfalfa is just too low in digestible fiber to be an optimal beef cow
feed. “Rocket fuel alfalfa” in a beef
system is only of incremental benefit in feeding out finishing steers. Grass is truly a more balanced forage feed
than alfalfa, which grew to prominence only because when in combination with
high energy corn it could appear to be a “balanced” ration on chemical tests.
The most profit in a beef cow-calf herd is to fully utilize the
rumen. Cattle raised on forages
will develop a full digestive capacity from that forage, and with appropriate
genetic selection on your cow genetics you can get growth, milk production for
calves, and nice body conditioning without the need for a third to half the
ration being corn and oilseed based. Beef
phenotypes should be selected for the ability to finish by age, not on weight
gain from grain.
