Welcome to the Herd!

We’re excited to welcome Poonam Vinayamohan as a part of our team! Poonam graduated with a degree in Veterinary Medicine in 2015. She received her PhD from UCONN where her research focused on horizontal gene transfer. Poonam started as a postdoctoral scholar in The One Herd Lab in 2020, where she will be working on resistome in livestock.

Congratulations To Our Recent MPH-VPH Graduates!

A huge congratulations to Andrew Vaughn and Daysia Reese on the completion of their MPH-VPH programs this semester!

Andrew’s project investigated the prevalence of genes associated with Shiga-toxin producing E. coli within livestock trailers and
holding pens of harvesting facilities. He discovered they are prevalent in both environments, indicating a clear need for better cleaning and disinfection.

Daysia’s project focused on characterizing Salmonella at livestock markets in Ohio and Wisconsin. She found plenty of Salmonella, but not the particular strain of interest (Salmonella Heidelberg) that caused an outbreak in 2016 and was linked to contact with male dairy calves.


Our new research takes an in-depth look into early life calf care

This week, we started a new, qualitative research study that takes an in-depth look into newborn dairy calf management. Our team will be traveling around Ohio and our colleagues at the University of Guelph will be traveling around Ontario, Canada to host focus groups with dairy farmers to better understand early life calf care. These discussions will help us identify specific barriers producers face related to early life care, and the long-term goal of this research is to overcome these barriers to improve calf health and welfare.

Our first focus group provided rich data with a great group of dairy producers! We are looking forward to hosting more discussions and comparing calf management practices between Ohio and Canada. Stay tuned!

Manuscript Publication Alert: Journal of Dairy Science

Our new publication in the Journal of Dairy Science is hot off the press! In a prior trial, lactoferrin treatment halved the mortality risk in pre-weaned dairy calves with GI disease, but the treatment effect was smaller and non-significant in this follow-up study conducted on multiple farms across Ohio. Excellent work, team!

Dr. Habing Engaged in the “Ask the Expert” Event at Farm Science Review

Dr. Habing fielded some tough questions about the impacts of antibiotic use in livestock during the “Ask the Expert” event at the Farm Science Review. The “Ask the Expert” event is an annual, collaborative extension education effort among faculty and staff from the College of Food, Agricultural, and Environmental Sciences and the College of Veterinary Medicine. The 20 minute presentations from the experts address important veterinary medicine and farm management challenges facing Ohio farmers. 

Jessica Garcia Wins First Place (Again!) For Her Work On Bacteremia In Calves!

Jessica Garcia, veterinary student and member of The One Herd Lab, was awarded first place in the student research competition at the American Association of Bovine Practitioners Annual Conference in St. Louis, Missouri! Jess’s work shows bacteremia in calves with diarrhea is much less common than we thought based on earlier studies. This novel finding suggests antimicrobials should be used only for severe cases.

Jess also placed first at the OSU CVM College Research Day for her outstanding poster presentation earlier this year.

Congratulations, Jess!!

The One Herd Lab Was Well Represented At The AABP Annual Conference!

Dr. Habing and veterinary students, Miranda Hengy and Jess Garcia, attended the 52nd Annual Conference of the American Association of Bovine Practitioners, September 12-14, 2019 in St. Louis, Missouri.

Dr. Habing engaged with colleagues as he presented two posters on genomic characterization and trends in the antimicrobial susceptibility of Salmonella Dublin recovered from Ohio cattle.

Miranda also delivered a poster presentation on the use of a novel technique, Sepsityper kit with MALDI-TOF, to detect bacteremia in diarrheic dairy calves.

Jess shared an oral presentation on the prevalence of bacteremia in diarrheic dairy calves, and the potential association of clinical signs with bacteremia.

Conference abstracts and full posters are available here. Great work, Team!

USDA-Animal Health-Formula Funds Awarded To The One Herd Lab!

Our Herd was recently awarded nearly $13,000 in USDA-Animal Health-Formula Funds to support the work of Ph.D. student, Samantha Locke. Sam’s work will focus on creating effective cleaning and disinfection protocols to eradicate Salmonella biofilms.

Keep up the great work, Sam!

Kent Weaver Presents At The 2019 National Veterinary Scholars Symposium

Kent Weaver, second-year veterinary student, presented his summer research at Tufts University Cummings School of Veterinary Medicine Tufts University during the the 2019 National Veterinary Scholars Symposium, the annual scientific colloquium which showcases research accomplishments by veterinary students completing summer research internships. The goal of Kent’s study was to use semi-structured interviews to develop an understanding of how dairy producers approach disease prevention and treatment on organic operations.

To learn more, check out Kent’s abstract and poster. Great work, Kent!
