Can Kelp Help?
While the majority of climate change research focuses on reducing and capturing carbon dioxide, less attention has been paid to methane emissions, despite the gas having 30 times the warming effect. Over a quarter of the United States’ total methane emissions are derived from enteric fermentation (cow burps) alone. Emerging research finds that feeding certain species of algae (seaweed, kelp or microalgae) to cattle can reduce their methane emissions by 80 to 99%. Unfortunately, most farmers and bovine nutritionists are unfamiliar with algae-based feed supplements, and the supplements are not always available and can be expensive.
A faculty member and graduate student in the Falk College of Sport and Human Dynamics are among a multidisciplinary team of over 50 researchers tackling this issue. Falk Family Endowed Professor of Food Studies Rick Welsh and graduate research assistant Michelle Tynan are part of the $10 million Coast-Cow-Consumer project, funded by the U.S. Department of Agriculture’s National Institute of Food and Agriculture’s (NIFA) Sustainable Agriculture Systems Program.
Welsh and Tynan have been surveying and interviewing conventional (non-organic) and organic dairy farmers, as well as dairy nutritionists, about their knowledge of algae-based feed supplements, the level of interest farmers and nutritionists have in feeding the supplements, and the barriers faced in implementation.
“Without dairy farmer and professional dairy nutritionists’ understanding and comfort with the technology, any potential benefits cannot be realized. Therefore, listening to and learning from farmers and other dairy professionals is key,” Welsh says.
Familiarity Key
Over the summer, Welsh and Marie-Claire Bryant ’22, who received an M.S. in food studies, held focus group sessions with organic and conventional farmers. They found that organic dairy farmers were more familiar with using algae-based feed supplements than conventional farmers, since many organic farmers already use it as a health care aid instead of conventional products, such as antibiotics. In focus group sessions, organic farmers explained their experience that feeding algae has improved cow fertility, reduced pink eye infections and lowered the incidence of mastitis of the udders.
Those sessions also revealed that conventional farmers were skeptical of the health claims, but could be interested as more science emerges and if using algae-based feed supplements is cost-effective.
Their reports also made it clear that farmers would adopt algae supplements to promote cow health—but not to reduce methane—unless a methane-reduction program was incentivized by the government, dairy cooperatives or milk manufacturing firms.
Nutritionist Survey
More recently, Welsh, Tynan and food studies graduate student Ryan Fitzgerald conducted a survey of dairy nutritionists at the Cornell Nutrition Conference. They found that most nutritionists do not recommend algae to their clients, not because they don’t believe it is effective, but because they don’t feel they know enough about it. The nutritionists wanted to see more peer-reviewed research showing the efficacy and safety of algae-based feed supplements.
Welsh and Tynan plan to continue surveying dairy farmers and nutritionists and will be working with other project members to understand the value of those supplements for improving farm income and herd health, as well as protecting the environment.
A Bonus Economy?
Popularizing algae-based feed supplements could also help another type of farmer—the lobster fishers of Maine, according to Welsh. Given algae’s ability to grow well in cooler Maine waters and its harvest period opposite the lobster season, it could provide an alternate source of income for that region. Algae (seaweed) is known for being able to sequester large amounts of carbon from the atmosphere, Welsh says.
Research on methane gas reduction is particularly pertinent now. President Biden recently announced new initiatives to address what his administration describes as “super-polluting methane emissions—a major contributor to climate change,” including emissions from beef and dairy systems. New York Gov. Kathy Hochul, in concert with the state’s Climate Action Council, also just announced goals to reduce greenhouse gas emissions by 40% by 2030 and 85% by 2050.
The Coast-Cow-Consumer project is now entering its second of five years. The project team includes researchers from Bigelow Laboratory for Ocean Sciences, Clarkson University, Colby College, Cornell Cooperative Extension, Kansas State University, University of New Hampshire, University of Vermont, William H. Miner Agricultural Research Institute and Wolfe’s Neck Center for Agriculture and the Environment.
“The opportunities for collaboration are as deep and wide as the ocean itself,” says researcher and graduate student Tynan. “We are hoping this research contributes to a sea change in methane reduction, sustainability and cow health.”
Memories We’ll Always Treasure
Each year, the Academy of Nutrition and Dietetics holds the Food & Nutrition Conference & Expo (FNCE). The Academy comprises the largest group of food and nutrition professionals in the world, and each year members from around the country travel to experience everything FNCE has to offer.
Unfortunately, the COVID-19 pandemic put a halt to FNCE. But after being held virtually for the past two years, the Academy and nutrition community was excited to welcome FNCE back in person this October in Orlando, Florida.
This year’s cohort of dietetic interns from Syracuse University were encouraged and supported by Falk College to attend FNCE. All 10 interns, along with multiple Falk nutrition faculty, traveled to Orlando for a weekend of networking, professional development, and fun!
FNCE 2022 did not disappoint and offered countless educational sessions, an impressive expo floor, and exciting networking opportunities. Each intern expressed immense gratitude for the opportunity to attend this inspiring event. As future dietitians, this was a valuable experience that inspired us as young professionals and reminded us of the important field we are working to enter.
When asked by our director to reflect on my experience, I noted that, “Connecting with other students and dietitians and hearing about their experiences and passions is inspiring and confirms that I am on the right track in becoming a dietitian.”
The conference was held from Oct. 8-11. After an exciting opening ceremony and hearing from Academy President and Syracuse University alumna Ellen Shanley, the conference began. There were sessions throughout each day, varying from topics such as sustainability to inflammation and malnutrition to cultural differences and accessibility.
There was truly no shortage of opportunities to learn. When the interns were not attending sessions or checking out research posters, we visited the expo floor. This year, more than 200 organizations attended FNCE. Brands and companies big and small showcased their products and services and to no one’s surprise, it was delicious!
Orlando showed its Orange spirit that weekend with representation from Falk College! Assistant Professor Jessica Garay presented research posters with student contributions titled “The Effect of a 3-month Lacto-ovo Vegetarian Diet Intervention on Diet Quality” and “The Effect of a 3-month Lacto-ovo Vegetarian Diet on Inflammation.”
Associate Professor and Undergraduate Director of Nutrition Kay Stearns Bruening presented a future practice poster titled “Focused interdisciplinary learning experiences improves awareness of interprofessional health profession skills.”
One of the most exciting events of the weekend was when the Syracuse University Dietetic Internship accepted the School Spirit Award. The interns and director Nikki Beckwith attended a reception with Academy President Shanley and heard words of professional advice from multiple academy board members. Nikki and interns were honored to accept the award from alumna Shanley and show their Orange pride!
The Syracuse community was so proud that one of our interns, Rebecca Garofano, presented this year. Rebecca and her research partner, Helen Midney, presented on their research titled “Food Solidarity: Lessons from a Farmworker Community’s Food Pantry Garden.” (In April, Garofano was honored with the Outstanding Dietetics Student Award by the New York State Academy of Nutrition and Dietetics.)
All nutrition students hear about FNCE and the amazing opportunity it provides, however after experiencing it firsthand, the Syracuse University dietetic interns agree that this is an understatement. Having the opportunity to travel as a program was a memorable experience. We left with knowledge and insight on diverse topics, connections to professionals in the fields, and memories we will always treasure.
Editor’s Note: Baker was joined in Orlando by nine other dietetic interns who are graduate students and will complete their internships in May: Asma Bukhari, Dahabo Farah, Rebecca Garofano, Natalie Krisa, Olivia Mancabelli, Maureen Philzone, Jennifer Pope, Sydney Teeter and Shenna Tyer.
