AABP Executive Director Dr. Fred Gingrich is joined by three veterinarians from Heritage Veterinary Partners, Dr. Luke Strehle, Dr. Tera Barnhardt and Dr. Dan Cummings. Cummings also serves as the AABP Membership Committee chair. This episode is sponsored by Heritage Veterinary Partners, a community of rural mixed animal and food animal veterinarians. Find out more information about Heritage Veterinary Partners at this link.
Rural veterinary practice can be isolating, especially for recent graduates who have built a community network of colleagues while in school. Providing opportunities for networking with other veterinarians can overcome the challenges of isolation for rural veterinarians. Cummings discusses a paper published in the Bovine Practitioner which was a qualitative analysis of experiences of recent graduates and how Heritage Veterinary Partners has used these assessments to build a community across their practice groups.
We also discussed the HPAI H5N1 disease outbreak in dairy cattle. Barnhardt and Strehle discuss how they worked within their practice group as well as how they managed this disease for their clients. Gingrich reminds our listeners that there is a dedicated webpage for AABP members with links and information on this outbreak.
Visit Heritage Veterinary Partners in the exhibit hall at the 57th AABP Annual Conference in Columbus, Ohio, September 12-14!

AABP Executive Director Dr. Fred Gingrich is joined by Dr. Brad White from the Kansas State University Beef Cattle Institute to discuss a paper published in the Bovine Practitioner titled “Risk factors Associated with Case Fatality and Treatment Success following Initial Bovine Respiratory Disease Treatment in Feedyard Cattle”. This paper was a retrospective analysis of existing feedyard data to identify potential relationships between risk factors known at the time of initial treatment for bovine respiratory disease (BRD) and treatment outcomes. The three post-treatment outcomes evaluated were first treatment success, post-treatment deaths from any cause, and post-treatment deaths due to BRD.
The investigators found the overall first treatment success for BRD to be 67.8% with all-cause mortality of 10% and BRD related mortality of 6.3%. White discusses associations found with each post-treatment outcome evaluated which can be useful information as veterinarians evaluate the success of their BRD treatment, prevention and control protocols for their customers, and define expectations with clients.

AABP Executive Director Dr. Fred Gingrich is joined by Dr. Eric Moore from Norbrook Laboratories, and Dr. John Sharpe, a practicing veterinarian in Kansas and a 2023 graduate of Kansas State University.
This podcast is sponsored by Norbrook. Having the right antibiotics is critical to successfully treating seasonal diseases. Norbrook offers a variety of effective and value driven solutions such as Noromycin 300 LA, Norfenicol Injectable Solution, Tulieve Injectable Solution, Enroflox 100 Injectable Solution, and Cefenil RTU. To learn more, contact your Norbrook sales representative, your animal health distributor, or visit the Norbrook website.
Sharpe discusses the seasonal variation of disease patterns he sees in his bovine practice and how these patterns influence antibiotic use as well as the producer’s bottom line. He also shares his experiences with the implementation of GFI #263 which transitioned the remaining medically important over-the-counter antimicrobials to prescription status with veterinary oversight. We also discuss how he, as a veterinarian, walks through his decision-making processes for selecting an antimicrobial to treat an animal, herd or in protocol development. Moore provides some background on the frustration producers face when they experience treatment failure, how prevention is the most important part of a stewardship program, and what antibiotics do not do so that producers can understand how to use them properly and promote animal health.
Listen to the previous podcast with Dr. Eric Moore on implementation of GFI #263 here.
Make sure to visit the Norbrook booth at the AABP tradeshow at the upcoming 57th AABP Annual Conference in Columbus, Ohio, September 12-14, 2024.

AABP Executive Director Dr. Fred Gingrich is joined by the chair of the AABP Milk Quality and Udder Health Committee, Dr. Pam Ruegg, to discuss a new resource available to AABP members that was developed by the committee.
This episode is sponsored by Boehringer Ingelheim and their 360 mastitis portfolio. Find out more information at this link. Join us in Columbus, Ohio at the 57th AABP Annual Conference and visit the BI booth in the trade show and attend the opening reception on Wednesday, September 11 sponsored by Boehringer Ingelheim.
The resource document we discuss provides guidelines for both the novice and experienced veterinarian. Find all committee resources on this page. These guidelines will assist veterinarians in a total milk quality program and include resources for monitoring udder health, mastitis detection and diagnosis, treatment of mastitis, and prevention of mastitis. Each topic discusses the body of knowledge needed by the practitioner and the capabilities needed to provide this service.
If you are interested in assisting the Milk Quality and Udder Health Committee, or any AABP committee, please go to the committee menu on the AABP website and select a committee to contact.

AABP Executive Director Dr. Fred Gingrich is joined by Dr. John Angelos, University of California-Davis, and Dr. Dustin Loy, Nebraska Veterinary Diagnostic Center, to discuss infectious bovine keratoconjunctivitis (IBK), commonly referred to as pinkeye. This is a multi-factorial disease that can sometimes be difficult to manage during outbreak situations.
Our conversation begins as a review of the major pathogens associated with IBK which includes Moraxella bovis and Mycoplasma bovoculi which are associated with the majority of cases submitted to diagnostic labs. Our guests also review the various risk factors associated with IBK including flies, mechanical trauma and viral infections. There are nine commercially available bacterin products, two conditionally licensed products, and autogenous vaccines to aid in the prevention of IBK in cattle. Our guests review some best practices for incorporating vaccination into herd health protocols as well as other prevention measures veterinarians may recommend to beef and dairy producers such as clipping pastures, fly control, mineral supplementation and managing viral risk factors.
When prevention fails, treatment protocols are important for veterinarians to develop for producers during both individual animal cases and herd outbreaks. Oxytetracycline and tulathromycin are two antimicrobials currently labeled in the U.S. for treatment of IBK in cattle. There are no Veterinary Feed Directive products labeled for IBK treatment, prevention or control and veterinarians should be aware that it is prohibited to write a VFD for an extra-label use of in-feed antimicrobials.
Veterinarians are an ideal resource to develop prevention and treatment protocols for managing IBK on beef and dairy operations. Continuing to monitor cases and risk factors can aid in managing this important disease.

AABP Executive Director Dr. Fred Gingrich is joined by AABP President Elect and AABP Annual Conference Program Chair Dr. Dave Sjeklocha. Sjeklocha thanks his program committee who are volunteer AABP members who develop the content for the conference.
The theme of the conference is “Challenge the Norm” and Sjeklocha states he picked this theme to encourage members to challenge themselves with what they are doing for their clients and continue to improve and advance their practice. The keynote speaker, Dr. Shawn Baker, will challenge the norm on assumptions about eating an animal-sourced diet and help our members advocate for the products that our clients produce. We will also hear from the AABP vice president candidates for 2025, Dr. Elizabeth Quesnell Kohtz and Dr. Jennifer Roberts, after the keynote address.
We walk through some of the highlights from the sessions including presentations on small ruminants, beef, dairy, clinical skills, practice management, student sessions and case competition, and research summaries. Sjeklocha also developed a cattle welfare track this year at the conference. This session will be for beef and dairy veterinarians and provide an opportunity for advancement in the field of animal welfare, an important part of our oath in caring for cattle.
The conference is typically planned 10 months in advance, but we leave two time slots open for hot topics. This year, we will hear a presentation on the draft updated AVMA Guidelines for the Depopulation of Animals, focusing on the cattle portion of the document. We will also have a panel presentation on Influenza A H5N1, providing attendees with experiences from a diagnostic lab, practicing veterinarian, and a producer who is a veterinarian and went through the disease. There will be ample time for question and answer during this panel presentation. Sjeklocha also describes the clinical forum breakfast presentations which are an additional two hours of CE facilitated by an expert and is discussion-based in a small-group format.
The AABP conference is not only about CE sessions, but networking and socializing opportunities as well. We have an opening reception sponsored by Boehringer Ingelheim, breakfast presentations from Diamond V and Zoetis, the scholarship presentation and Amstutz Scholarship Auction sponsored by Zoetis, Stampede 5K sponsored by Boehringer Ingelheim and the Saturday Awards and Business Lunch sponsored by AABP. We also will have a student reception sponsored by Endovac and the student Quiz Bowl sponsored by Vaxxinova/Newport Laboratories.
Reminder that the early-bird registration discount ends August 1, and online registration and hotel block closes August 22. We encourage all attendees to book in the AABP hotel block and only use the online AABP housing link to ensure your room confirmation. You can reserve your hotel and read the guide to hotels on this page.

AABP Executive Director Dr. Fred Gingrich is joined by AABP Vice President and Preconference Seminar chair Dr. Callie Willingham to discuss the many opportunities for advanced learning in seminars at the upcoming AABP conference, Sept. 12-14, in Columbus, Ohio (preconference are Sept. 8-11, others are during conference). Seminars are small group meetings led by an expert faculty and are approved for 8 hours per day of additional continuing education credits.
We discuss how seminars that we have taken have advanced our practice skill set, provided opportunities for new or expanded services for clients, created billable hours, and allowed networking with colleagues and faculty with similar professional interests. This year there are eight seminars offered prior to the conference at the headquarters hotel, three seminars offered off-site with wet lab instructional opportunities, and three seminars during the conference. Each seminar is limited to 30 attendees which offers low attendee-to-faculty ratio for interactive learning.
Students are welcome to attend the seminars, as well as sign up for the Student Lameness seminar to learn proper hoof trimming and surgical techniques from members of the AABP Lameness Committee.
Seminars that have an inadequate number of registrations by August 1 are subject to cancellation. We encourage you to register for the conference and a seminar prior to that date. If you are registered for a seminar that cancels, your registration fee can be applied to an alternative seminar or is 100% refundable. Seminars are an AABP member benefit and therefore limited to AABP members who are registered for the conference. If you are taking a seminar that occurs prior to the conference and not attending the conference itself, there is a reduced seminar-only registration fee.
Find information about the seminars offered this year at this link. When you go to that link, you can click on the seminar title to view the faculty list, seminar fee and a detailed agenda of topics that will be discussed. Register for the AABP conference on this page.

In this episode, AABP Executive Director Dr. Fred Gingrich is joined by Dr. Richard Doak to discuss the National Milk Producers Federation (NMPF) Farmers Assuring Responsible Management (FARM) Program.
This episode of Have You Herd? is sponsored by Boehringer Ingelheim and their 360 coverage mastitis portfolio. For more information, visit this link.
Doak begins the discussion by explaining why it is important to have a national dairy farm audit program to demonstrate continual improvement to milk buyers and consumers. Doak has a unique perspective because he is a private practice veterinarian, provides third party audits, trains evaluators and serves on the task force for NMPF that is charged with reviewing and updating the standards which are ultimately approved by the NMPF board of directors. Version 5.0 of the FARM program begins on July 1, 2024 and it is important for veterinarians to review with producers the updated standards so they are prepared for their next audit. There are not a lot of significant changes in this version but there have been updates to the standards on lameness, colostrum feeding and humane euthanasia.
We discuss training and the importance of training. Doak mentions that training occurs every day on dairy farms and veterinarians are an important part of training to protect the safety of people and animals, prevent residues, and improve animal health. Although training occurs all the time, it must be documented for the FARM program. The five focus areas for training occur when the animals are most vulnerable and include newborn calf care, down cow management, humane euthanasia, fitness to transport and stockmanship. This training can mitigate risk for dairy farms and is another reason to provide and document the training.
AABP members who are interested in preparing their clients for FARM Version 5.0 can attend a seminar during the conference. More information about this seminar can be found here and the registration page for the conference can be found on this page.

AABP Executive Director Dr. Fred Gingrich is joined by Dr. Isaac Jumper, Assistant Professor at Mississippi State University College of Veterinary Medicine to discuss the paper “Case-control study to identify management practices associated with morbidity or mortality due to bovine anaplasmosis in Mississippi cow-calf herds” published in the Bovine Practitioner and available open-access in the online first edition. Jumper starts by discussing bovine anaplasmosis and the challenges associated with its control in cow-calf herds.
The objective of this study was to determine if management practices, such as feeding chlortetracycline (CTC), are associated with illness or death from bovine anaplasmosis in Mississippi cow-calf herds. We discuss some of the epidemiologic terms used in the paper and the results of the study. This study found that providing CTC was associated with case herd status and Jumper provides some possible explanations for this finding. Veterinarians should routinely review protocols, especially antimicrobial protocols for treatment, prevention and control of disease, to optimize antimicrobial stewardship and animal health.

In the 200th episode of the AABP Have you Herd? podcast, AABP Executive Director Dr. Fred Gingrich is joined by Dr. Jessican Klabnik, a theriogenologist on faculty at Auburn University College of Veterinary Medicine. Klabnik was one of the authors on a paper published in the Online First edition of the Bovine Practitioner. This case series paper evaluated the surgical success and reproductive performance of bulls undergoing surgery for correction of penile deviation.
Klabnik reviews penile deviation syndrome in bulls which can include spiral, ventral or sigmoid deviations due to an abnormality in the dorsal apical ligament. Surgical correction or culling are the only management considerations for these bulls; however, there is a lack of peer-reviewed data on the outcomes from surgical correction. Klabnik discusses some of the challenges with collecting data from these 25 cases with 10 cases meeting the inclusion criteria for the study.
The surgery does not have a high risk of complications and was deemed successful in seven out of the ten bulls evaluated. Of these seven, six bulls achieved intromission and five sired progeny. Although this study represents a small number of cases, the surgery appears to have a 50:50 success rate, but due to the low risk of complications, bulls that do not successfully return to herd sire capabilities can still be culled for salvage value.
This case series report can help to guide veterinarians performing bull breeding soundness exams when they observe a penile deviation, and also help veterinarians in private practice or referral institutions when evaluating bulls as surgical candidates.

AABP Executive Director Dr. Fred Gingrich is joined by AABP member Dr. Dave Krahn to discuss a disease that may be unfamiliar to many listeners – infection from hematogenous mycoplasma species. Krahn has been a practicing dairy veterinarian in central Wisconsin since graduating from veterinary school in 1989.
This episode of Have You Herd? is sponsored by Addison Biological Laboratories, manufacturers of MAXI/GUARD Pinkeye Bacterin and Moraxella bovoculi bacterin to protect your herd before pinkeye season. For more information, visit https://addisonlabs.com/.
We start our conversation by reviewing the characteristics of the hematogenous mycoplasmas and clinical signs that may be attributable to infection. Diagnosis of the disease is done via PCR and a presumptive diagnosis can be made via a blood smear to look for the organism on red blood cells. Krahn worked with university partners to do a study on his client’s herds as well as a prevalence study in Michigan and Wisconsin which found that 100% of farms were positive for one or both of the organisms. The within herd prevalence for hematogenous mycoplasmas was 75%.
Krahn has implemented protocols for use of pasteurized colostrum for feeding calves and individual needle use for all injections to control the spread of the disease. He reports that herds show a resolution of clinical signs within 4-6 months after implementation of control measures.

AABP Executive Director is joined by Dr. Justin Kieffer, a Clinical Veterinarian Associate Professor at The Ohio State University to discuss a paper published in June 2023 in Translational Animal Science. The paper evaluated a water-based medium-expansion foam as a method for depopulation of adult cattle. Kieffer defines depopulation and euthanasia as well as describing the differences between the two terms. Euthanasia methods can be used for depopulation, however limitations can make them difficult to implement in cattle should a large scale depopulation event be required. Kieffer discusses currently approved depopulation methods for cattle described in the AVMA Guidelines for Depopulation of Animals and the limitations of currently available methods.
This study evaluated if a water-based foam could be used to depopulate cattle in a specially designed trailer. Kieffer mentions that a small pilot study was first performed with the animals under general anesthesia to validate their methods before moving to the large study in un-anesthetized animals. This study was approved by the Institutional Animal Care and Use Committee (IACUC) at Ohio State. Biologgers were used to track activity and electrocardiograms. Average time to fill the trailer with foam was 90 seconds, cessation of movement was 2.5 minutes and time to cardiac death was 8.5 minutes which is similar to euthanasia methods such as gunshot or penetrating captive bolt.
Kieffer reviews some of the advantages identified with this method as well as considerations for what method of depopulation may be employed on a farm. Consideration should be given to the effect on human mental health during these events. He also mentions some the importance of research in this area to ensure that in the event a mass depopulation event occurs, we have the tools needed to perform the procedure.

AABP Executive Director Dr. Fred Gingrich is joined by Dr. Jeffery Hall, a technical services veterinarian with Huvepharma and the coordinator for an AABP seminar titled "Practice Applicable Beef Cow Nutrition.” AABP recognizes the challenge of attending seminars before the conference and has expanded our CE offerings to include seminars outside of the annual and recent graduate conferences. The purpose of these seminars are to offer a small group setting where attendees can go home and immediately offer a new service or improve and expand a service they are currently offering to clients.
We walk through the topics that will be taught during this seminar and their importance to veterinarians. Hall describes how veterinarians can get involved with the vitamin and mineral nutrition program for the beef cow producer clients and make an impact on health, productivity, economics and immune function. This seminar is also being taught by Dr. Chris Chase, who will review the impacts of nutrition on immunology. Dr. Dave Rethorst will discuss cow-calf nutrition and impacts on fetal programming as well as some ration balancing skills for veterinarians. Attendees will also learn about feeding cows and evaluating feedstuff opportunities during drought situations.
This seminar was conducted at the 2023 AABP Annual Conference in Milwaukee, Wis., and has been expanded to a two-day course based on feedback from participants. Additional topics included in this seminar will cover fly control and coccidiosis control for cow-calf ranches. Hall also discusses the wet-lab portion of this seminar where attendees will learn how to perform a liver biopsy on live beef cows. Attendees will be able to go home and implement this service to their cow-calf clients as well as interpret and make management recommendations to their clients.
This seminar will be held at The Ohio State University Marysville Large Animal Ambulatory Clinic June 27-28, 2024. This facility recently underwent a remodel with an excellent handling system to perform the wet-lab. The seminar has been approved for 15 hours of continuing education in jurisdictions that recognize RACE approval. A hotel block has been reserved for attendees to secure rooms. The cost of the seminar is $450 and includes lunch each day.
Attendance is limited to 20 attendees and we encourage interested AABP members to register today. For more information and to register for this seminar and book your hotel room, visit this link.

AABP Executive Director Dr. Fred Gingrich is joined by Dr. Clint Stonecipher, a rangeland management specialist with the US Department of Agriculture - Agricultural Research Service - Poisonous Plant Research Laboratory. Stonecipher was the first author of the paper published in Volume 58 Number 1 in the Bovine Practitioner. Salvia reflexa is a plant in the mint family sometimes known as lance leaf sage and often is seen on dry range pastures. Stonecipher reviews this case report which affected two herds with mortalities due to the hepatotoxic effects of this plant. We walk through the clinical presentation and the diagnostic investigation. Stonecipher also discusses a survey as part of this publication where plant specimens were analyzed in 12 different states and submitted to the poisonous plant research laboratory. He also provides some tips for veterinarians who are investigating suspected intoxications and how to work with the laboratory for diagnostic submissions.

AABP Executive Director Dr. Fred Gingrich is joined by guest Dr. Sharif Aly, an epidemiologist at the Veterinary Medicine Teaching and Research Center in Tulare, Calif. Aly graduated from Cairo University and practiced in Egypt before coming to the United States for advanced studies in preventive medicine and epidemiology. His team developed and published the BRD 100 and BRD 10K studies to identify various risk factors for Bovine Respirator Disease (BRD) in dairy calves.
Aly explains the incidence of BRD in calves and how it has failed to improve despite improvements in tools for detection and prevention. We review the risk of various areas on BRD including colostrum management, housing, season, environment and nutrition. He also discusses the role of on-farm diagnostics and the California and Wisconsin scoring systems that veterinarians can use with producers to manage BRD risk in dairy calves, including the BRD scoring system developed into an app for on-farm use.

AABP Executive Director Dr. Fred Gingrich is joined by Dr. Pat Gorden and Dr. Michelle Buckley from Iowa State University to discuss two publications from the Bovine Practitioner Volume 57 Number 2, 2023. Links to the published papers are at the end of the podcast show notes.
Our guests review the use of internal teat sealants and some of the challenges with producer use of internal teat sealants. We also review the importance of equivalence studies for practicing veterinarians, who are the target audience for papers in the Bovine Practitioner. The first study discussed was an equivalence study comparing two different internal teat sealants. The take-home message from this study for practicing veterinarians is that both products studies demonstrated equivalent results when comparing the outcome variables studied.
The second paper evaluated the persistence of the internal teat sealant in the mammary gland during the dry period. This paper was from one herd and looked at migration of the teat sealant from the teat into the cistern of the mammary gland using radiographs as well as strip yields after freshening. The authors also investigated if location of the internal teat sealant impacted risk for new intramammary infection during the first 120 days in milk.
Both of these studies are relevant to the practicing dairy veterinarian as they work with clients to implement dry-off protocols to decrease the risk of mastitis and improvements in milk quality.

AABP Executive Director Dr. Fred Gingrich is joined by Dr. Gerard Cramer, Associate Professor at the University of Minnesota and current chair of the AABP Lameness Committee. This podcast is sponsored by Boehringer Ingelheim and their 360 mastitis portfolio. What’s in your cattle tool care kit? Experience the power of complete mastitis care at choose360coverage.com.
The topic of the discussion is to walk through a research project that was funded by the AABP Foundation to investigate a model for inducing sole ulcers in dairy cattle. Sole ulcers are one of the major causes of lameness in dairy cattle and yet we still have much to learn about the pathogenesis of this disease to improve prevention and treatment strategies. Cramer discusses the importance of proof-of-concept studies to benefit future research and how they approached the welfare implications of this study. Three induction model challenges were implemented in this study included lying time restriction, dry matter intake restriction and a lipopolysaccharide challenge. Cramer reviews the results of the study and the difficulties in successfully inducing sole ulcers in this group of cows.
We also discuss some of the limitations of this study and future research opportunities to improve our ability to prevent and treat sole ulcers in dairy cows which can improve the welfare of cows. The AABP Foundation supports advancements in the health, well-being and productivity of cattle through scholarship programs, educational opportunities, and applied clinical research that benefits present and future cattle veterinarians. Research projects that are funded by the AABP Foundation must be applicable to practicing cattle veterinarians, have limited opportunity for funding elsewhere, and can serve as seed money for future larger-scale projects. The AABP Foundation research projects are supported entirely by member donations. Please support this type of research by donating today at this link.

In this episode, Dr. Fred Gingrich is joined by AABP members Dr. Michelle Barrett and Dr. Becky Funk. Both guests have served on the Amstutz Scholarship Committee and Funk is the past-chair of the AABP Foundation.
Our guests discuss the scholarship application process, how scholarships are reviewed, and offer tips for filling out the application. Students who qualify for a scholarship should consider applying using the links on the Students menu of the AABP website. We discuss the requirement for a CV/resume for some scholarships, and what to consider including in that document. Questions are also asked for all of the scholarships and answering these questions is part of the review process.
Letters of recommendation are also considered by reviewers. Tips for asking for a reference as well as how to provide a good letter of reference for a student are great pointers for those applying. Finally, we remind students to make sure to not wait until the deadline date and time to finalize your application. This includes making sure your dues are renewed well in advance of the deadline and checking the scholarship/grant portal to make sure your letters of reference are submitted by the deadline. Incomplete applications are not reviewed.
A special thank you to all of the donors to scholarship funds and AABP member volunteers from committees who review the scholarship applications. If you are interested in joining a committee, please contact [email protected]. Donate to the AABP Foundation scholarship funds at this link.
