Farm Description
Our farm consists of less than
40 acres. We raise registered performance horses, registered dogs, pastured poultry and
registered Boer meat goats on a small farm in Northern Missouri.
Goal
Our goal is to reestablish a
grass-legume pasture, to restore balance to the plant community on the
farm, improve pastures, and increase the stocking rate using
multi-species Management-intensive Grazing. My
husband and I would like our small farm to be profitable, to support our
lifestyle choice, and to function without causing permanent damage to
the ecosystem. We wish to be sustainable.
Project Description
In 1998, we received a SARE
(Sustainable Agriculture Research and Education) Grant from the Missouri
Department of Agriculture to explore biological weed control using meat
goats. Our weed-choked, eroded pastures will not support enough
livestock for our farm to be profitable. The pastures must be improved
and Management-intensive Grazing (MiG) with goats, horses, and poultry
appears to be the best way to do it. Current challenges to improving
pastures include: a tree-shaded bottom; an impenetrable thicket of
multiflora roses, berry brambles, and creeping vines; steep, eroded land
overgrown with thorny locust, scrub cedar, sumac, buckbrush, and
hardwood sprouts; and hay ground choked with thistle, cocklebur,
milkweed, ragweed, and other noxious weeds.
Common methods of weed control
include using herbicides or burning. Both methods have long-term
consequences such as groundwater and air pollution, and provide only a
short-term solution to the problem of unwanted plant species.
Mechanical removal is expensive due to fossil fuel and labor costs and
is impractical or impossible on our steep pasture and soft bottom
ground. My husband and I prefer biological weed control.

The Project
Initially, we conducted a weed
survey and created a map that showed where palatable forages existed.
To start restoring their pastures, we began building MiG paddocks and
portable shelters for our goats. We also reinforced our perimeter
fences to securely contain all of our livestock. The goats were used
intensively on target areas and were kept where they were needed with
electric fencing. After dividing the farm into four equal sections with
electric fencing we then cleared the weeds and brush though MiG of meat
goats. After the goats had cleared the paddock of undesirable growth we
moved the goats into the next paddock and released our horses into the
previously grazed section. The MiG increased the stocking rate of the
farm and produced desirable changes in plant populations and soil
conditions.
Measuring
Success
As a result of this three year
study, we determined that our farm benefited in three major ways:
Ecologically: Using
goats to clear and control weeds will return pastures to productive use
without using herbicides, fossil fuels or burning. Manure from the
goats will be spread over the ground as the animals are rotated from
paddock to paddock, adding nutrients to the soil.
Economically:
Improving unproductive pastures will allow a higher stocking rate for
horses and pasture poultry, and will provide the potential for increased
income. The meat goats can be used for weed control, and then sold to
provide additional income for the farm.
Socially: Grazing weedy
pastures with goats will reduce noxious weed populations on the farm and
prevent weeds from spreading to neighboring farms. Neighbors will not
have to worry about herbicide drift or nitrate runoff. The community
will gain a local source of pastured poultry, goats, and horses.
Outreach
In an effort to promote the use of goats
for weed control and to share information with other producers, we
sponsored farm walks each year of our project. We cooked and served
goat meat to introduce the community to a novel meat. We continue to
take visitors through our operation and advise them on the duplication
of similar MiG operations on their farms.
We continue to participate in goat field
days, sponsored by the University Extension, by providing animals and
giving demonstrations. I was a featured speaker at the National Small
Farm Trade Show and Conference held in Columbia, Missouri in 2000 where
I spoke about using meat goats to control weeds. In 2005, I was awarded
a seat at the Sheep & Meat Goat Training Program at the Missouri
Livestock Symposium. I maintain a library of materials on the subject
of meat goats and share this information with others.
Results
In the first year of this
project, we took soil samples and surveyed the weeds and grasses growing
in the pastures. The initial soil sample results were better than they
anticipated. In the past, the land had been overgrazed and mismanaged,
however, the soil had not suffered severe deficiencies and there was no
serious erosion. However, the initial weed and grass survey was very
discouraging. The main grass present was fescue and the survey found
many species of weeds dominating the pasture, including poisonous
species. In the wooded areas, little or no valuable timber was
discovered. Existing undergrowth was crowding and stunting desired
species.”

By using MiG, we gained a
tremendous amount of knowledge about goats and managing our pastures.
We learned that goats eat weeds first, then leafy brush and only consume
grass when there is no preferred browsing available. By utilizing this
knowledge, we have been able to profit from previously undesirable plant
growth. Instead of completely eliminating the unwanted species, we have
learned to manage it and turn it into a profitable food source for our
animals. We allow the goats to graze first, letting them eat weeds and
brush and then remove them before the growth is killed out. Then we
turn the horses into the paddock and allow them to eat the remaining
choice grasses. They are removed before the grass is cropped too
closely, and then the goats are returned to finish off the weeds that
have been exposed by the selective grazing of the horses. The pastured
poultry is used to control parasites and distribute manure in the
paddocks.
Conclusion
After MiG of goats, we have seen
a definite reduction of weeds and undergrowth. Overall pasture condition
has improved; undergrowth has been reduced or entirely removed. We see
increased vigor in the pasture grasses and additional, palatable species
are now present due to the reduced competition. We have tripled the
stocking rate of goats on this farm and have doubled the stocking rate
of the horses and introduced day range poultry for added diversity. Our
use of anthelmentics (de-wormers) has decreased and we believe this is
due to rotational grazing and the reduction of parasite re-infestation
through multi-species grazing. Farm revenue has increased annually
since the onset of this project.
