Round Bale Silage
Justin McCullough
Decision Case Study-
Agroecology Internship 2003
The Situation:
A young farmer is milking a small dairy heard in western Pennsylvania.
He has limited funds for building structures and does not have room
on his farm property to build silos or other kinds of forage storage
facilities. He has concerns about twisted stomach that has been
occurring in some of the neighbor’s cattle. Twisted stomach
can be caused by lack of rumen stimulation or rumen buffers. Today’s
grain feeds contain mostly shelled corn and other ground up grain
products and the silage is cut into small pieces that do not provide
much rumen stimulation or buffers. Longer pieces of forage in the
silage may provide the stimulation needed to prevent twisted stomach.
He has all the necessary hay making equipment including discbine,
tedder, and a silage special round baler, and a forage harvester.
He also has two 60’ Harvestor Silos that he uses for corn
silage. His employees include a 17 year old high school student
who helps him with the milking and during the summer months. During
the summer months he is available to do most farm work and is quite
capable in the tractor seat. Also available to him is his retired
neighbor who helps him during busy times with field work and is
also able to do most tractor operations, but is getting up in age
and can’t do strenuous labor and can’t stay out in the
heat for long periods of time. He is considering whether to fill
a silage bag or to purchase an inexpensive 3-point bale wrapper
and make round bale silage for his cattle, or any other options
that his local extension agent may suggest.
The Options:
Two of the options being considered use different pieces of machinery
and have different storage and forage texture aspects. Silage bags
require relatively large flat areas to be placed. The machinery
involved include a discbine, forage harvester, at least two forage
wagons, and a bagger machine. This option will require at least
three tractors all of which need to be in the 80-100 horsepower
range.
Making round bale silage
or balage requires much of the equipment the farmer already has.
The only thing that he will need to purchase will be a bale wrapper
which costs $8000 new or much less money for a used one. The other
equipment needed for the process he already has: a discbine, tedder,
and a silage special round baler. The wrapped round bales can be
stored almost anywhere and are transported very easily by a skid
loader or a bucket tractor with a bale spear on the loader.
The Question:
It is now the first of the year and the farmer is considering what
he should do for the next spring season? What do you think: should
he go with the silage bags or with the round bale silage?
