Kansas State University with Beef Cattle Institute (BCI) and Butterfly Network Collaborate in Research on Lung Point-of-Care Ultrasound (POCUS) for Chute-side Decision Making to Manage Bovine Respiratory Disease (BRD).

September 23, 2024

BRD is the number one cause of mortality and morbidity in cattle around the world. New  research done by BCI on Butterfly’s Ultrasound-on-ChipTM iQ+ Vet technology enables  cattle operations all over the world to utilize this data in real time, creating a new  decision making process to diagnose and manage BRD.

Burlington, MA., NEW YORK, NY, and Manhattan, KS – Butterfly Network, Inc. (NYSE: BFLY),  a digital health company transforming care with handheld, whole-body ultrasound, and Kansas  State University with BCI announce results to a comprehensive research project around using  point-of-care ultrasound (POCUS) in chute-side decision making for Bovine Respiratory Disease  (BRD) in feedlot cattle. The research project and proof of concept prior to the study were all  done with the Butterfly iQ+ Vet. The ultrasound-on-chip technology enables the research to be  applied in real life conditions making this research applicable to cattle operations all over the  world.  

Bovine respiratory disease (BRD) is the most frequent and economically impactful disease of  post-weaned beef cattle. When considering all direct and indirect economic losses, on top of  increased mortality, BRD poses substantial economic burdens to the industry, estimated at  $800 million to $900 million annually. (Chirase and Greene, 2000). Another more recent study  estimated that BRD continues to be the most significant production problem facing the beef  industry, accounting for the majority of morbidity, mortality, and production losses in feedlots  with estimated annual economic losses in excess of $2 billion (Powell, 2013). 

One of the major challenges is confirming accurate diagnoses in the field as multiple syndromes  can cause similar clinical signs of disease in cattle. Multiple pathogens contribute to BRD  development, and differentiating BRD from other pulmonary syndromes is important in selecting  appropriate therapy. Determining the extent of disease progression influences animal  management decisions. BRD occurs frequently and improved ability to accurately evaluate  cattle disease states improves antimicrobial stewardship and animal welfare management.  

Advancements in diagnostic and treatment technologies are essential for promoting animal  welfare, enhancing productivity, and ensuring the economic sustainability of cattle production. For commercial use technologies need to have the ability for implementation without  unnecessary restrictions on operational flow by providing real-time results and the ability to work  in a variety of cattle handling environments. 

Several studies were conducted focusing on enhancing BRD diagnostic and prognostic  accuracy in an effort to improve management practices for feedlot cattle, emphasizing animal  welfare and antimicrobial stewardship. An initial study showed promising results using point of  care ultrasound (POCUS) to distinguish BRD (bronchopneumonia) from another type of  pulmonary disease (interstitial pneumonia). Increased diagnostic precision chuteside would  allow customization of therapeutic program to match the specific disease syndrome.  Differentiating interstitial pneumonia from other respiratory illnesses is important due to the  influence on treatment strategies and management decisions. Antimicrobial therapy is common  in bronchopneumonia cases due to their infectious nature, whereas interstitial pneumonia  typically requires anti-inflammatory or supportive treatments to address the underlying  pathogenic mechanisms. (Woolums, 2015) 

“Accurately identifying disease in cattle is challenging, and chuteside tools to augment health  assessments can be valuable to animal health caretakers. More precise estimates of the  animal’s disease status can lead to better therapeutic and management decisions. The ability to  gain real-time insights at the time of treatment is a great tool for cattle producers and  veterinarians.” said Dr. Brad White,  

Two studies were completed evaluating the prognostic value of POCUS in cattle treated for  respiratory disease. In one study, several ultrasound parameters such as B-line count, lung  consolidation, B-Line area, and moth sign presence leading to an ultrasound lung score were  associated with the likelihood of treatment failure in cattle at the initial time of treatment for BRD.  This information is valuable as alternative therapies could be evaluated in animals more likely to  be a treatment failure. In a study evaluating animals with multiple previous treatments, ultrasound parameters like B-Line, B-line area, and presence of moth sign were associated with  the likelihood of an animal being non-recoverable. These results could be used to distinguish  cattle that may need to be managed differently to provide optimum care. The substantial  economic impact of chronically ill cattle shows the need for effective management, making the  use of chuteside diagnostic tools crucial for improving prognosis and treatment decisions.  (Feitoza, L., et al, 2024) 

The research underscores the importance of precise chute-side diagnostics in enhancing  prognostic accuracy, improving animal welfare, and supporting antimicrobial stewardship. Initial  findings have been presented at several national meetings and final results are in process of  submission to peer-reviewed journals.  

“The use of the Butterfly iQ+ Vet in the feedlot and cattle care setting demonstrates Butterfly’s  commitment to extending our powerful Ultrasound-on-Chip™ technology into more markets  where innovation is needed,” said Jenna Mutch, Vice President, Veterinary of Butterfly Network.  “With iQ+ Vet, we move outside of our core point-of-care veterinary ultrasound market to better  address the care setting for the cattle market, which has long awaited a more affordable, user friendly, durable, and fast solution. The use of traditional piezo-electric crystal is limited by  tempertaure, environment, speed, durability, and the need to clip and use gel . We listened to  the unique needs of our cattle customers, did proof of concept testing, and then put the iQ+ Vet to the test in the 2 studies successfully scanning and aquiring images and cine clips of over  1200 head of cattle in over 24 hours worth of live scanning time. ” 

Butterfly iQ+ Vet is the world’s only single probe, whole-body, multi-species imaging solution.  The iQ+ Vet is the second-generation of Butterfly’s veterinary ultrasound device and brings  sharper imaging, a new procedural guidance tool, and hardware improvements that make the  solution more powerful, versatile, and easy-to-use on all species in the environment needed to  successfully diagnose.
