As the world grows larger, the question remains: Can we feed it?
The future of the food system at large, and the livestock industry in
particular, depends on two critical areas: addressing environmental impact and
identifying areas where sustainability can be increased — from livestock farmers
all the way to the consumer plate. Regenerative agriculture
techniques,
carbon
capture,
waste reduction and other techniques that strive to eliminate the impact of
farming are already gaining popularity.
For livestock farmers, however, sustainability could also involve breakthrough
work that occurs well before the life of a pig or a cow even begins. For more
than six decades, ongoing advancements have enabled farmers to produce
high-quality, affordable meat and milk more efficiently and sustainably —
through innovations in animal genetics and breeding.
The results — with respect to developing a more sustainable global food system —
are quite stunning. Today, dairy farmers produce 60 percent more
milk with
herds that, on average, are three times smaller than they were 70 years ago.
Also, compared to 1977, today’s farmers produce the same amount of beef with 33
percent fewer cattle, per data collected by the
USDA. And, according to the National
Pork
Board,
it takes five pigs to produce 1,000 pounds of pork; 60 years ago, it took eight
pigs.
This data indicates that scientifically driven, ethically sound animal genetics
and breeding technologies are the linchpin to a more sustainable food system.
Animals are healthier and more productive; farmers are better able to meet the
growing global food demand; and measurable reductions are taking place in
greenhouse gas (GHG) emissions, as well as in the use of water, land and other
natural resources.
Genetics-driven health and sustainability, in action
That’s exactly what is happening at Ebert
Enterprises — a sixth- and seventh-generation
family-owned and -run dairy farm in Algoma, Wisconsin. Jordan Ebert, who
at age 28 is the business development officer for his family’s farming
operation, explains in this
video
that data and technology are having a sizable impact on how they use genetics to
produce better, healthier and more productive cattle.
“The animal is at the center of our farm and our industry,” he says. “If the
consumer has a smiling face from a bowl of ice cream or a glass of milk, it all
stems back to the animal that makes that happen. If we focus our attentions on
improving the (animals’) lives, we’re going to have a more sustainable
industry.”
Animal breeding has occurred for thousands of years. But now it is much more
precise, thanks to advanced science and technology — with a key benefit of
creating healthier and more productive livestock that require fewer inputs. One
example is promoting tolerance to diseases such as Porcine Reproductive and
Respiratory Syndrome Virus (PRRS), which can wipe out entire herds; an
Iowa State University
study
estimated that PRRS costs the US pork industry about $664 million annually.
Because PRRS — an airborne virus — cannot be effectively prevented or treated
through traditional veterinary medicines or vaccinations, the only viable
solution is to raise animals that, through a gene-editing process, become
resistant to the effects of the disease.
It may sound futuristic, but gene-editing technology can help effectively create
disease-resistant animals. The innovative tool, known as CRISPR
Cas-9, is well-tested and proven
to be effective; in fact, it’s the same science behind research being used to
identify and combat serious diseases in humans, such as cancer and sickle cell
anemia. CRISPR Cas-9 is an arm of gene editing in which certain genes that make
animals susceptible to debilitating diseases can be “turned off.”
By accurately analyzing animals’ DNA and looking for markers linked to
susceptibility to pathogens, we can stop threatening diseases before they can
start impacting animals’ health and welfare. And that sets the stage for
generation after generation of healthy and more sustainable livestock for years
to come.
Transforming our global food system
Science-driven genetic and breeding innovations extend far beyond disease
resistance; as we at Genus continue to harness our
growing knowledge of genetics, genomic science and data, we are applying that
science to make discoveries that address real-world problems by lowering uses of
antibiotics in livestock, producing less
methane,
and developing even more protein from fewer animals.
But we need to build on the significant progress we have already made. By
quantifying and illustrating how genetic improvements reduce greenhouse gas
emissions, we can inspire further improvements in efficiency and sustainability
across the entire food system. In doing so, we can broaden the benefits to
farmers, consumers, and the environment.
As the world’s population grows, we must remain diligent to unearth innovations
that provide ample and healthy food sources. The result? A more sustainable food
system with less impact on environmental resources thanks to animals that are
resilient to climate change and disease, and can produce plentiful, healthy
protein for our ever-growing planet.
