Sustainability in nutrition and livestock production
Post by Clemson undergraduate Hannah Jellema
The
concept of sustainability, while most often used to refer to environmental
practices, can be used in many different contexts. In the past week I have seen
it applied to successful bull breeding practices, livestock finishing
processes, forest management practices, and to the production of organic goat
cheese.
Visiting
the Weschenfelder feedlot and meeting with the owner of the lot allowed us to
see the behind-the-scenes measures taken to ensure that the cattle being fed
are kept healthy and grow at an efficient rate. Each group of cattle sent to
the feedlot is fed a formulated ration that caters to the desires of the cattle
owners. Some groups are fed a higher protein diet than others, and certain
supplements are sometimes mixed in with the feed. For example, an anti-bloat
supplement called Rumensin was mixed in along with daily feed at the lot that
we visited. It was interesting to discover that something so innocent as bloat
could be detrimental to livestock. When thinking about the way human-managed
cattle have lived in the past, it is easy to see that their lives today are
pretty easy in comparison. However, it was still exciting to hear about research
going on at Montana State concerning more sustainable and animal-friendly
methods of finishing livestock. Devin, a researcher at the university, is
investigating the feasibility of using the wheat stubble on post-harvest lands
in place of feedlots. By grazing sheep on land that would otherwise sit
post-harvest, she was able to combine ranching and farming in a way that used
less resources while simultaneously providing a happier environment for livestock
to live in. The issue with this method is that it would require farmers to put
up expensive fencing around their fields. Once again, money proves to be the
main barrier between sustainable practices and cost-effective management.
Another aspect of sustainability
that we addressed this week was the successful management of forests. We met
with forester Jeff Hermans, who explained to us how controlled burns reduce the
risk of large, uncontrolled forest fires. By periodically thinning and burning
pines, land owners can prevent destructive fires that devastate the areas they
cross, sometimes creating barren landscapes that persist for decades. In this
part of the US it may take 100 years for a pine tree to grow to a height which
a pine tree in South Carolina can grow to in 25 years. Because of this, the
impacts of fire resonate much more seriously in Montana. Therefore, in order to
manage land to sustain future livestock projects, stand thinning and periodic
controlled burns prove to be useful tools.
My absolute favorite part of the
week was touring Amaltheia Organic Dairy in Bozeman. The owner of the
operation, Melvin, provided us with an opportunity to see how successful an
organic operation can be. Part of his success stems from the increasing market demand
for pesticide-free products. It is interesting to consider how much power
consumers have on the market, and ultimately over their impact on the
environment. It is also somewhat ironic that traditional methods of farming
used by people who lived in Montana in the past are once again becoming popular
due to an increase in demand for organic products. Since ranchers and farmers
can frequently increase their profit margin by switching to certified organic
means of production, it is often in their best interest to pursue
sustainability. This is not always the case when it comes to environmentally
friendly practices, but as consumers we all have the opportunity to encourage
resource-efficient production.
Finally, we capped off the week with
a visit to the Midland Bull Test facility, where each year over a thousand
bulls are tested on characteristics such as gain efficiency and fertility. The
owner of the operation, Steve, reinforced the idea that there is an aspect of
sustainability to bull breeding. Oftentimes, breeders focus so much on
selecting for popular characteristics related to size and productivity that
they ignore other important traits, such as healthy hooves that allow animals
to travel and graze successfully. By overlooking these aspects, producers may
produce lower quality bulls.
Throughout
the past week in Montana, the only thing that I was consistently reminded of
was that everything changes. From forest management techniques to feedlot
designs, there is always new research and information being put out into the
world. This means that today’s methods for doing things will only last so
long. Sometimes, new information can be
revolutionary and result in more sustainable practices, and sometimes it may
have the opposite effect. In all cases, however, it is important to consider the
needs of the stakeholders who are being affected by research and development.
